The outer coating of welded pipe FBE fused epoxy powder (FUSION BOND EPOXY) anti-corrosion steel pipe is a new type of anti-corrosion coating developed in the past 30 years. The coating has the characteristics of simple coating operation, no pollution, good impact resistance and bending resistance, and high temperature resistance, and has been widely used abroad. Powder coating is…
Read MoreCold rolling refers to the processing of steel plates or strips into various types of steel through cold working such as cold drawing, cold bending, and cold drawing at room temperature. Carbon steel pipes are divided into two categories: hot-rolled and cold-rolled (drawn) steel pipes. Carbon steel pipes are made of steel ingots or solid billets through perforation into…
Read MoreSpiral pipe (SSAW) is also called spiral steel pipe or spiral welded pipe. It is made by rolling a low-carbon structural steel or low-alloy structural steel strip into a tube blank at a certain helical angle (called a forming angle), and then welding the tube seams. It can produce large diameter pipes from narrower strips. Spiral pipes are mainly…
Read MoreDue to the increasing bearing pressure of the pipeline, the use conditions are becoming more and more severe, and the service life of the pipeline should be extended as much as possible. In order to improve competitiveness, carbon steel pipe manufacturers should research and innovate in what aspects, and what are the main development directions of spiral welded pipes?…
Read MoreHydraulic test is a method to detect the defects of SSAW steel pipe, which is widely used in the inspection of various pressure steel pipes.When the steel pipe is subjected to the hoop tensile stress during the hydrostatic pressure test, if the performance of the steel pipe does not meet the requirements or has defects, it will bend, crack,…
Read MoreSeamless steel tube is an important type of steel pipe in production and life. It is an important steel that is relatively strong and durable in steel pipes. The seamless steel pipe will also encounter bending and deformation in use. When encountering the bending and deformation of the seamless steel pipe, as long as it can be corrected, the…
Read MoreAccording to the standard requirements, the dimensional inspection of seamless steel pipes mainly includes the wall thickness, outer diameter, length, curvature, ovality and end face shape of the steel pipe. (1) Wall thickness inspection The tool used for wall thickness inspection is mainly a micrometer. During inspection, use a micrometer to measure the wall thickness of the steel pipe…
Read MoreIn the production process of spiral steel pipe, if the production process is unreasonable and the machine parameters are not properly set, there will be deviations, especially for large-diameter spiral steel pipes, which is often referred to as the wrong side phenomenon. During the production of spiral steel pipe, the wrong side occurs from time to time, and there…
