About carbon steel pipe tubing
Tubing is used to transport fluids and gases in a variety of pneumatic, hydraulic, and process applications. Tubes are usually cylindrical in shape, but may have round, rectangular, or square cross-sections. Tubing is specified in terms of outside diameter (OD) and, depending upon the material of...Read more -
Advantage of galvanized spiral pipe welding process
Galvanized pipe welding processes can be divided into spiral welded and straight seam welded, and galvanized spiral welding process is relatively wider number of applications, but also more complex. Galvanized spiral pipe welding method is first out of the forward end portion of the electrode abo...Read more -
304 stainless steel seamless pipe annealing temperature on alloying elements
Production 1000MPaCP standard cold rolled steel annealing cycle is reheated to the annealing temperature of the critical zone, then cooled and maintained at about 400 isothermal deg.] C, above the martensite start temperature (Ms). 1. The volume percentage of ferrite and carbon content area that ...Read more -
3PE coating pipes
Pipe has three layer PE antisepsis structure: the first layer with epoxy powder (FBE> 100um), the second layer with adhesive (AD), 170 ~ 250um, the third layer with polyethylene (PE) 2.5 ~ 3.7mm. integration of them and solid steel pipe make form a good coating. Diameter range 60mm-1420mm, wal...Read more -
304 stainless steel seamless pipe thermal stress
304 stainless steel seamless pipe due to internal thermal stress caused by a thermal embrittlement of 304 stainless steel seamless pipe at the seams due to different coefficients of expansion eye when heated produce a lot of heat stress, especially during rapid temperature changes due to thermal ...Read more -
3LPP coating application in submarine pipeline
With the continuous development of offshore oil and gas fields, pipelines for transporting the amount of offshore oil and gas is growing. Currently coating structure submarine pipelines used mainly 3LPE and FBE. 3LPE long-term use temperature generally does not exceed 70 ℃, short-term up to 80 ℃....Read more
