18 Years Factory Cold Rolled Steel Tinplate - API 5L Steel Line Pipe Plate – Haihui
Short Description:
18 Years Factory Cold Rolled Steel Tinplate - API 5L Steel Line Pipe Plate – Haihui Detail:
Modern pipeline steel is a low-carbon or ultra-low-carbon microalloyed steel, which is a product with high technical content and high added value. Most of the new technology achievements in the metallurgical field in the past 20 years have been applied to the production of pipeline steel. The development trend of pipeline engineering is large pipe diameter, high-pressure rich gas transportation, high cooling, high corrosion use environment, and subsea pipeline wall thickness. Therefore, modern pipeline steel should have high strength, low Bauschinger effect, high toughness and brittleness resistance, low weld carbon content and good weldability, and resistance to HIC and H2S corrosion.
The pipeline steel plate is used to manufacture welded line pipes, because seamless line pipes are made of round bar, not steel plates. Medium thick plate is generally used to produce thick wall straight seam welded pipe, and the coil steel is used to produce electric resistane welded(ERW) pipe and spirally submerged arc welded(SSAW) pipe. Nowadays, more and more clients require pipeline steel plate to produce line pipes because the steel plates can be used to manufacture bigger diameter pipes, in addition, the price of welded pipes is usually lower than that of seamless pipes.
Line pipe steel plate is key material for production of ERW line pipe, LSAW line pipe, SSAW line pipe, which are used in pipe line construction in oil, gas and water transport, it can be used in manufacturing pressure fluid transmission construction.
Extremely low arctic temperatures, extreme pressures in the deep ocean, acid media: even the most fierce conditions have no negative effect on our linepipe plates. Linepipe plates are able to work in depths of up to 2,800 meters below the sea surface.
We also offer roll-bonded clad offshore structural steel plate with a corrosion-resistant cladding for the highest demands in sour-gas application. As a specialist in modern thermo mechanical rolling technology with accelerated cooling, we are among the world’s industry leaders.
