Welded line pipe dealer
Line pipe are either made of Seamless or ERW. ERW line pipe are made from welding of end of coil following API 5l Standard. IF Welding for low frequency and Ultra IF for High frequency is used. For oil and gas storage, the best recommended type is ERW longitudinal, owing to its quality, ease of transport and cost.
API 5L Steel line pipe generally in carbon steel. Mostly used for Transportation of Petroleum product working in extreme situation with high temperature and high pressure. Ace Metal Exim Stock API 5L grade B Pipe in India.
Advantage of Line pipe as below:
- Smooth Surface
- Strong and lighter Wall thickness
- Cheaper than Seamless Line pipe
Welded pipe can also be supply in high-frequency induction (HFI) resistance pressure welding technique for longitudinal welding. The endless strip passes through rolling stands where it is shaped to an open pipe, which runs through a high-frequency inductor consisting of a metal coil with single or multiple windings. As a result, high-frequency ring current is induced into the pipe that closes preferably at the strip edges which converge in the welding point. The temperature required for welding is generated by resistance heating of a narrow zone along the strip edges.
