3PE Coated Steel Pipe 3LPE Coating Pipes Winsteel Group

Apr 01, 2019 · 3PE coated steel pipe is commonly used in the pipeline project. As carbon steel pipe is widely used in pipeline systems for transportation of oil, gas, water and other fluids. In such cases, they should have high resistant to corrosive from chemicals, moisture, harmful environment and etc. So it is necessary to make pipes coating to anti-corrosion. China Pipeline Seamless Steel Pipe Manufacturers If you're going to buy high quality pipeline seamless steel pipe in stock, welcome to get more information from our factory.Because of professionalism, the high-quality ASTM A213 Steel Seamless Pipes Tubes, seamless welded pipe, Steel Pipe JIS G 3459 we offer can always show outstanding advantages, and the application solutions and technical

High Frequency Induction Welded Pipe, HFI pipe - Sunny Steel

The 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 J55 Oil casing pipe weldability analysis Worldiron steelJul 12, 2019 · The harsh environment of oil casing requires not only high quality of the pipe itself, but also of the welding. API 5CT J55 is a commonly used oil casing pipe material. This artcle aims to analyze its weldability by analyzing alloy elements and carbon equivalent of J55 piping. NICKEL ALLOY PIPE AND FITTINGS Stainless Steel Pipe Nickel alloy pipe and fittings has good welding performance, compared with the ferritic stainless steel and austenitic stainless steel, it is neither like ferritic stainless steel weld heat affected zone, as grain coarsening and make the plastic toughness sharply lower,
