What are the differences between the surface processing of spiral steel pipes and stainless steel pipes
Original surface of stainless steel pipe: NO.1 The surface that is heat treated and pickled after hot rolling. Generally used for cold-rolled materials, industrial tanks, chemical industry equipment, etc., with thicker thicknesses ranging from 2.0MM-8.0MM. Blunt surface: NO.2D After cold rolling,...Read more -
Basic introduction to high-pressure boiler steel pipes
High-pressure boiler steel pipes: mainly used to manufacture high-quality carbon structural steel, alloy structural steel, and stainless heat-resistant steel seamless steel pipes for steam boiler pipes of high pressure and above. These boiler pipes are designed to work under high temperatures and...Read more -
The difference between submerged arc welded spiral steel pipe and straight seam high frequency welded steel pipe
Submerged arc welding spiral steel pipe uses continuous welding wire as the electrode and filler metal. During operation, the welding area is covered with a layer of granular flux. The large-diameter spiral tube arc burns under the flux layer, melting the end of the welding wire and part of the b...Read more -
Large-diameter welded pipe production process
1: Conduct physical and chemical inspections on raw materials such as strip coils, welding wires, and fluxes. 2: The head and tail of the strip are butt-jointed using single-wire or double-wire submerged arc welding. After being rolled into a steel pipe, automatic submerged arc welding is used fo...Read more -
The principle of anti-corrosion steel pipes
Coating anticorrosion is a uniform and dense coating formed on the surface of de-rusting steel pipes, which can isolate it from various corrosive media. Steel pipe anti-corrosion coatings are increasingly using composite materials or composite structures. These materials and structures must have ...Read more -
What is the service life of carbon steel tube?
Carbon steel tubes are made of steel ingots or solid round steel through perforation into capillary tubes, and then made by hot rolling, cold rolling or cold drawing. Carbon steel tube plays an important role in my country’s steel pipe industry. Carbon steel tubes come according to your med...Read more
