Dsaw welding
DSAW welding of principle: Submerged arc welding is the use of arc welding heat, And manual electrode arc welding is different: submerged arc welding wire is exposed above without paint, however, what usually see manual welding electrode above is with a very thick layer coatings, submerged arc fl...Read more -
Difference between Hot Stretch Reducing Pipe and LSAW Steel Pipe
Difference between hot stretch reducing pipe and LSAW steel pipe are basically has the following two points: 1, Resulting in differnce on product quality due to the different processes, hot stretch reducing also carried out a process after high-frequency welding process that lsaw steel pipe can n...Read more -
Density of Carbon Steel Pipe
Density is one of the numerous properties of steel. It is calculated by dividing the mass by the volume. Steel comes in many different forms. Density is calculated by dividing the mass by the volume. The density of carbon steel is approximately 7.85 g/cm3 (0.284 lb/in3). There are many uses for s...Read more -
Deoxidation iron requirements of seamless steel pipe
Deoxidation iron requirements of seamless steel pipe: Size: In the case of continuous charging, the size of the direct reduced iron is very important parameter. Small in size (1 ~ 2mm) materials may quickly oxidized when contacting the slag, it may be pumped flue. Size is too large (> 30mm) at...Read more -
Cooling rate of X80 pipeline steel welding heat affected zone
For long-distance natural gas pipeline, using high grade pipeline steel is the main way to save costs. Canada’s pipeline industry practice proved that: compared with the X60, adoption of X70 pipeline wall thickness can be reduced 14%;Compared with X70, adoption of X80 pipeline wall thicknes...Read more -
Cold rolled steel pipe
Cold rolled steel pipe is produced through cold-rolled process. Cold-rolling is at room temperature for a further rolled to a target thickness of the thin plate. And comparison of hot-rolled steel, cold rolled steel plate thickness is more accurate, and the surface is smooth, beautiful, but also ...Read more -
Cold drawn seamless steel tube process
Cold drawn seamless steel tubes process: round tube → heating → perforation → Heading → annealing → pickling → oiled (copper) → multi-pass cold drawn (cold rolled) → blank tube → heat treatment → straightening →hydrostatic testing (testing) → mark → storage. Cold drawn steel tube is with ...Read more -
