Data is everywhere and the modern world runs on data. For most kinds of data communications, different end users can communicate with each other through the assistance of some servers that mediate the process. However, this can cause increased response times, lapse in data security, and additional server costs. Moreover, if the server is down for some reason, entire data communication comes to halt. With peer-to-peer communication, you can eliminate the need of an intermediate server to communicate and exchange data with each other directly. For cross-platform communications using web browsers, one such technology is WebRTC.
For real-time media communications like voice, video and data transfer natively between browsers and devices, WebRTC is the only protocol available and most brands are adopting the technology to build applications that enable communications between different device types.
What is WebRTC?
WebRTC application development is an API-based Communication between mobile applications and web browsers developed by Google in May 2011. It is standardized jointly by the World Wide Web Consortium (W3C) and the Internet Engineering Task Force (IETF) and allows developers to create basic web apps that use the camera or microphone, or more advanced video-calling and screen sharing applications.
Some of the popular applications and platforms using WebRTC are:
Google Meet and Google Hangouts
Facebook Messenger
Discord
Houseparty
GoToMeeting
Zoom meeting
How does WebRTC work?
The WebRTC technology is made up three major components:
Media Capture and Stream
Media Capture and Stream, fetched using the getUserMedia function, allows the developers to access the digital cameras, webcams, microphones, or shared desktops from a peer’s device.
Peer Connection
Peer Connection, accessed by creating an RTCPeerConnection object, is used to establish a WebRTC connection between two or more peers. All WebRTC interactions can only begin by establishing this connection between the participating peers. RTCPeerConnection handles audio and video transmissions, encryption, and bandwidth configuration
Data Channel
Data Channel, accessed by creating an RTCDataChannel object, initiates data transfer between two peers to exchange arbitrary data, such as files, with one another.
How can WebRTC benefit your Business Growth?
In the next five years, as published in the reports by PRNewswire, the global WebRTC market is expected to grow at a rate of 46%. During the recent pandemic, the entire world was forced to work from home whenever applicable. At such moments, the benefits of working remotely were discovered and this trend led to wide scale adoption of WebRTC applications. With real-time communication, you give your customer three major abilities:
Power to interact
Power to communicate
Power to collaborate
When you use WebRTC to develop applications and devices that solve your customers’ needs in a unique way, you create a monopoly. Here are some of the examples where WebRTC can help certain businesses flourish:
Home furnishings: Using virtual assistants such as Alexa, Google, Siri, and Cortana, people are turning their house into smart homes with devices talking with each other and turning on or off based on the voice commands. For a home appliance brand, having IoT enabled devices and keeping the data communication between them secure, it is worthwhile to invest in WebRTC.
Healthcare: In cases where the patient cannot be physically brought for a doctor’s appointment or when consulting a doctor overseas, organizing a video call is a viable option. The end-to-end encryption ensures the conversation remains secure between the patient and the doctor.
Delivery: As more and more brands are considering adding drones in their delivery fleet, they need to make sure the video feed from the drone remains uninterrupted and secure. WebRTC is a great option to ensure both criterias.
Heavy industries: In factories and industries, repair and maintenance of heavy machinery may sometimes require the technician to travel frequently. Using the video call technology powered with WebRTC, equipment troubleshooting or machine supervision can be managed virtually.
Education: Teachers and educators can easily conduct online classes and disseminate notes and study materials easily using the WebRTC technology.
Event managers: By organizing virtual festivals and celebrity events and live streaming it, you can increase ticket revenues while eliminating geographical borders. WebRTC can allow fans to watch their idols live from the comforts of their home and celebrities can conduct meet-and-greet programs easily.

Causes of wrong edges of large-diameter spiral steel pipes (SSAW):
In the production of large-diameter spiral steel pipes, misalignment occurs from time to time, and there are many influencing factors. In production practice, steel pipes are often degraded due to dry misalignment and out-of-tolerance. Therefore, it is necessary to analyze the causes of wrong edges of large-diameter spiral steel pipes and preventive measures.
1. The sickle bend of the steel belt is the most important factor causing the wrong edge of the steel pipe.
In the forming of spiral welded pipes, the sickle bend of the steel strip will continuously change the forming angle, resulting in the change of the weld gap, resulting in seams, staggered edges and even overlapping edges. The quality of the steel pipe is seriously affected. Therefore, observe the sickle bend of the steel strip after uncoiling. By controlling the vertical roll, the disc shear can cut off part of the sickle bend. The continuous control and correction of the forming angle are to reduce the sickle bend of the steel strip during the production process. An effective way to produce wrong sides.
2. Due to the poor shape and dimensional accuracy of the head and tail of the untrimmed steel strip, it is easy to cause the steel strip to bend hard and cause the wrong side to be caused by the butt joint.
3. When the reinforcement of the welding seam of the head and tail butt welding of the steel strip is large, if the over-forming is not handled properly, it is easy to cause a large misalignment.
4. The poor condition of the edge of the steel strip is another important reason for the wrong edge.
Spiral steel pipe production process:
(1) The raw materials are strip steel coils, welding wires, and fluxes. Strict physical and chemical inspections are required before investment.
(2) Butt joint of strip steel head and tail, using single wire or double wire submerged arc welding, after coiling into steel pipe, automatic submerged arc welding is used for repair welding.
(3) Before forming, the strip undergoes leveling, edge trimming, edge planing, surface cleaning and conveying, and pre-bending treatment.
(4) The electric contact force meter is used to control the pressure of the cylinders on both sides of the conveyor to ensure the smooth conveying of the strip.
(5) Externally controlled or internally controlled roller molding is adopted.
(6) The weld gap control device is used to ensure that the weld gap meets the welding requirements, and the pipe diameter, the amount of misalignment and the weld gap are all strictly controlled.
(7) Both internal welding and external welding adopt American Lincoln electric welding machine for single-wire or double-wire submerged arc welding, so as to obtain stable welding quality.
(8) The welded seams are all inspected by the online continuous ultrasonic automatic flaw instrument, which guarantees 100% non-destructive testing coverage of the spiral welds. If there is a defect, it will automatically alarm and spray the mark, and the production workers will adjust the process parameters at any time according to this to eliminate the defect in time.
(9) Use an air plasma cutting machine to cut the steel pipe into individual pieces.
(10) After cutting into a single steel pipe, each batch of steel pipes must undergo a strict first inspection system to check the mechanical properties, chemical composition, melting condition of the weld, the surface quality of the steel pipe and the non-destructive inspection to ensure that the pipe manufacturing process is qualified. Only later can it be officially put into production.
(11) The parts with continuous sonic flaw detection marks on the welds are re-examined by manual ultrasonic and X-ray.
eliminate.
(12) The pipes where the butt-welded seams of Fe-steel and the J-joint intersecting with the spiral welds are all inspected by X-ray television or filming.
(13) Each steel pipe undergoes a hydrostatic pressure test, and the force adopts a radial seal. The test pressure and time are strictly controlled by the steel pipe hydraulic microcomputer detection device. The test parameters are automatically printed and recorded.
(14) The pipe end is machined to accurately control the verticality of the end face, the bevel angle and the obtuse edg.

Piling spiral steel pipeSSAW is a spiral seam steel pipe made of strip steel coils as raw materials, often extruded and formed by automatic double-wire double-sided submerged arc welding. So, what is the piling spiral tube like during construction? How is the piling spiral tube produced? The following spiral tube manufacturers will introduce to you.
1. Penetration of piling pipe
1) Before construction, the control of sample piles should be rechecked one by one according to the original design drawing and the proposed axis line, and the measurement records should be made. Piling construction can only be carried out after the recheck is correct. After the pile-driving spiral pipe pile is transported to the site, it is hoisted with one-point lashing when it is hoisted to the pile position to insert the pile, and the pile-driving spiral pipe pile is aligned with the previously released pile position to ensure that the penetration is accurate and vertical. Before pile driving, a special pile cap must be placed on the pile head, and a hardwood damping pad must be placed on the pile cap. Placed on the top of the pile, it will self-sink, and a large amount of penetration will penetrate into the soil. After it is settled to stability, hammering will be carried out;
2) At the beginning of piling, the piling opportunity will be driven empty due to the large penetration. When starting the hammering operation, the test driving should be slowly interrupted until the pile enters a certain depth of the ground, and continuous hammering shall not be allowed. Piling process
In the process, the verticality of the guide rod of the pile driver and the pile must be corrected at any time, and the pile hammer, pile cap and pile must be kept on the same longitudinal axis;
3) After the pile-driving spiral pipe pile is driven into 1 ~ 2m, the verticality should be re-corrected. When the pile is driven to a certain depth and the quality of the piling is good, then continue to be beaten until it is 60cm~80cm above the water surface to stop the hammering. Connect the piles and repeat the above steps until the design elevation is reached. If the pile position is found to be inclined during the construction process (>1/100L L: steel pile length), it should be adjusted in time or pulled out the steel pipe pile and re-construction;
4) The buried depth of pile driving spiral pipe pile: 10m through the riverbed, and the sinking amount within one minute of percussion does not exceed 5mm.
2. Connect the pile
The pile-driving spiral pipe pile body connection adopts the butt welding of the pile body up and down. Before welding, the deformed and damaged part of the lower pile pipe must be trimmed, and the rust, water or oil sludge sand at the end of the upper pile pipe must be removed and polished.
Make good welding joints so that the gap between the upper and lower piles is 2 ~ 4mm. At the same time, multi-layer welding is used. After each layer of welding seam is welded, the welding slag should be removed in time, and the appearance inspection should be carried out.Add welding block to strengthen the connection of the upper and lower piles. After welding, it must be cooled for more than 5 minutes before hammering and piling.
3. Welded pile cover
After the construction of the pile-driving spiral pipe pile is completed, sand is manually poured into the pile to the top of the pile, and the pile cover is welded on the upper part of the steel pipe pile, and at the same time, 8 to 12 anchor steel bars of 20 mm are welded on the outer wall.
Pile driving spiral pipe production process:
(1) The raw materials are strip steel coils, welding wires, and fluxes. Strict physical and chemical inspections are required before investment.
(2) Butt joint of strip steel head and tail, using single wire or double wire submerged arc welding, after coiling into steel pipe, automatic submerged arc welding is used for repair welding.

(12) The pipes where the butt-welded seams of Fe-steel and the J-joint intersecting with the spiral welds are all inspected by X-ray television or filming.
(13) Each steel pipe undergoes a hydrostatic pressure test, and the force adopts a radial seal. The test pressure and time are strictly controlled by the steel pipe hydraulic microcomputer detection device. The test parameters are automatically printed and recorded.
(14) The pipe end is machined to accurately control the verticality of the end face, the bevel angle and the obtuse edg.
Tips: ERW welded pipe is formed by rolling strip and welding the seam, with tighter dimensional tolerances and less weight. The weld seam is heat treated after welding that no untempered martensite remains, and the weld flash can be removed from both inner and outer surfaces. ASTM A53 ERW steel pipe is a typical carbon steel pipe. It is largely used to convey fluids at low / medium pressures such as oil, gas, steam, water, air and also for mechanical applications.
