Seamless steel pipes are composed of various elements in steel. These elements are combined in different proportions to form different mechanical properties of seamless steel pipes. The amount of any element will directly affect the mechanical properties of seamless steel pipes.
Read moreThe basic reasons for defects in cold drawn seamless steel pipes are:
Read moreThe size tolerance of seamless steel pipe is mainly the diameter tolerance and wall thickness tolerance.
Read more1. The fixed-length spiral steel pipe may not be bundled.2. If there are threaded buckles at both ends of the spiral steel pipe, it should be protected by a thread protector. Apply lubricating oil or anti-rust agent to the threaded fasteners. Both ends of the spiral steel pipe are breached, and nozzle protectors can be added at both ends according to requirements.
Read moreStraightening is an important process in the production of seamless and welded steel pipes. Especially API standard oil casing and oil and gas pipes, steel casing pipes and special pipes for mechanical equipment, which have high quality requirements.These kinds of steel pipes not only have strict requirements on steel grade and weld quality, but also have high requirements on straightness of steel pipes.
Read moreThe welding seam leveling machine processes the weld seam of the stainless steel welded pipe on-line, and repeatedly rolls the inner and outer weld seams of the welded pipe synchronously, so that the weld seam transitions smoothly with the base material, making the seam welded pipe seamless and highlights the advantages of the welded pipe.
