The production process of welded steel pipe can be divided to LSAW- Longitudinal Submerged Arc Welded, SSAW Spiral Submerged Arc Welded and Straight seam Electric-Resistance Arc Welding. The process of welded steel pipe. Raw material testing, milling, pre-bending, forming, pre-welding, inte...

The production process of seamless steel pipe can be generally divided to hot rolling, and cold rolling. The production process of hot rolling pipe: billet preparation and checking - pipe billet heating - punch - pipe rolling - diameter steel pipe heating again - set or reduce diameter - heat tr...

1.What is the meaning of sch10? Pipe schedule (sch) is not the wall thickness, it's the wall thickness series.The actual wall thickness of the pipe with same diameter is different in different pipe number. Sch10 is just one type of pipe schedule. 2.What is the actual wall thickness of sch10...

1.What is galvanized steel pipe? Galvanized steel pipe is ordinary steel pipe coated with a layer of zinc. It can be divided to hot deep galvanizing and cold galvanizing. Cold galvanized pipes have been banned. 2.What is the production processing of galvanized steel pipe? There are two pro...

A: Stainless steel pipe is a hollow long round steel, mainly used in industrial transportation pipelines and mechanical structural parts such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrumentation, etc. In the south of China, Wenzhou & Wuxi cit...

As a manufacturer of steel pipes, sometimes people will ask us: do you know where to buy used steel pipes? The answer we give is: we don’t suggest to buy used steel pipes. Although the used steel pipes is little cheaper than the new steel pipes, they can’t guarantee the quality. And after ...

First we shoud know what is dom steel pipes. To produce specialty tubing, this procedure uses a drawbench to pull tubing through a die and over a mandrel, allowing excellent control of the inside diameter and wall thickness. dom steel pipes is work hardening that occurs. During cold drawing, t...

Tubing is a pipeline that transports crude oil and natural gas from the oil and gas layer to the surface after drilling is completed. It is used to withstand the pressure generated during the production process. Oil pipe specifications: 8-1240 × 1-200mm The outer diameter of the tubing is gen...

This product has been laser welded using a high-energy and high-density beam for a precise, narrow, and deep penetrating weld for excellent corrosion resistance. Our small diameter stainless tubing is well suited for both fuel and brake line applications. Features a mill finished inner diameter (...

Engineers or designers who need to transport hot fluids through pipes over long distances need to take into account the natural heat losses that will occur along the way. These thermodynamic calculations can be quite complicated, unless certain assumptions are made, a stable condition and the lac...

Cold drawn seamless pipe is a seamless steel pipe with high dimensional accuracy and good surface finish for precision mechanical structures, hydraulic equipment or reinforced sleeves. Difference between cold drawn seamless steel pipe and hot rolled seamless steel pipe The production process ...

Hot finished seamless tube also be caled hot rolled seamless steel pipe,Hot-rolled seamless steel tubes are rolled at a temperature above the recrystallization temperature. Hot rolling is rolling performed above the recrystallization temperature. Hot finished seamless tube delivery status G...
