CN102430901A - P110 steel level high frequency straight

A P110 steel level high frequency straight welded pipe manufacturing method comprises (1) taking hot-rolled coil as raw material; (2) shaping the coil into a straight seam pipe by continuous shaping techniques, welding the straight seam on the pipe by a high frequency inductive welding machine to produce a primary pipe, and after the welding, timely removing external and internal burrs of the China High Frequency Induction Welded Pipe, HFI Pipe In High Frequency Induction (HFI) Welded Pipe production process, hot rolled steel coils are fed with a high capacity accumulator in order to achieve continuous welding. HIGH-FREQUENCY WELDING is a welding process in which the heat source used to melt the joining surfaces is obtained from high-frequency (HF) alternating current (ac) resistance

Cold Rolled 2 X 4 Rectangular Steel Tubing , Welded Pre

Cold Rolled 2 X 4 Rectangular Steel Tubing , Welded Pre Galvanized Steel Pipe . Product features - Moisture-proof, anti-corrosion, non-fading - Simple and generous shape, excellent shock resistance - Special size and materials can be ordered . - Design according to customers' requirements . Differences between Hot Rolled and Cold - Permanent SteelAug 20, 2020 · The outer diameter of hot-rolled seamless pipe is generally greater than 32mm and the wall thickness is 2.5-75mm. The diameter of cold-rolled seamless pipe can be up to 6mm and the wall thickness can be up to 0.25mm. The outer diameter of thin-walled pipe can be up to 5mm and the wall thickness is less than 0.25mm. Distinguish hot-rolled steel pipe,welded steel pipe and Distinguish hot-rolled steel pipe,welded steel pipe and cold-formed steel pipe from the appearance. Hot-rolled steel pipe:It is relative to cold rolling, cold rolling is rolling below the recrystallization temperature, and hot rolling is rolling above the recrystallization temperature. Welded steel pipe:refers to a steel pipe with seams on the surface that is welded into a round or square shape with steel strips or steel

Fracture of high frequency straight welded pipe - United Steel

Mar 28, 2018 · The fracture of high frequency longitudinal welded steel pipe, hydraulic (pneumatic) components are used to design mechanical properties, brittle fracture and the use of temperature dependent components. It is found that when the temperature is lower than a certain temperature, it is found that the data will become brittle and the impact absorption work decreases obviously.
