API 5L Seamless line Pipe J55

Q:What is the difference between seamless steel pipe and welded pipe?: Such as hydraulic equipment pipeline connection. The weld seam of common steel pipe is its weak link, and the quality of weld is the main factor that affects its overall performance. People who have lived in the north have experienced the experience of freezing pipes and pipes in winter, and the places where they burst are usually welds. Welded pipe is not seamless steel pipe.

Q:What's the difference between stainless steel seamless tube and stainless steel welded pipe?: Stainless steel welded pipe is also a hollow section of steel, but it is welded through the plate into the steel pipe, so there is a welded steel pipe welding gap.

Q:Theoretical weight of 25*25*1.5 square steel tubes: The theoretical weight of 25*25*1.5 square steel tubes is 1.075kg/m.

Q:How seamless steel tube is formed?: Seamless steel tubes are formed by cold drawing and hot rolling.

Q:What kind of argon arc welding wire is used for 16Mn steel pipe?: 16Mn steel weldability is very good, general use TIG with J50 welding wire, hand arc welding with J506, J507 and other welding rod

Q:What does GALV mean in a steel tube?: GALV is the abbreviation of English galvanized (Galvanized), which means galvanized steel pipe.

Q:Difference between cold rolled steel pipe and common steel pipe: 1, from the dimension accuracy above, cold-rolled steel pipe size is good, high precision2. from the outward appearance, the surface of cold-rolled steel pipe is bright, and the surface of hot rolled steel pipe has obvious oxide skin or red rust

Q:Is there any difference between HFW steel pipe and ERW steel pipe?: Resistance welding, as the name suggests, resistance welding is a method of welding by welding electrode after exerting pressure on electrode and utilizing electric current through the contact surface of connector and adjacent zone. High frequency welding: high frequency current through the metal conductor, will produce two kinds of peculiar effects: skin and proximity effects, high frequency welding is the use of these two kinds of effects of steel pipe welding, the effects of the two is based on the high frequency welding metal.

Q:Which is more load-bearing, the same thickness of steel pipe and steel bar?: The magnitude of the axial force acting on the steel member is only related to three factors, namely, the strength of the material, the sectional area of A and the longitudinal stability factor of F.

Q:Is the steel frame on each floor supporting formwork (floor) called full scaffolding?: After the use of full scaffolding, more than 3.6 meters of interior wall decoration is no longer calculated decorative scaffolding, and the interior wall of the scaffolding is still in accordance with the provisions of the scaffolding.

The company's main products are: the low-pressure boiler seamless steel pipe, oil casing seamless pipe, ship seamless steel tubes, seamless steel pipe, petroleum cracking, chemical fertilizer equipment, seamless steel tubes, structural seamless steel pipe, seamless steel hollow pumping rod with eight series. According to GB, ASTM, APL5L, AP15CT, DIH, JIS and other standard production seamless steel tubes.
