Selection of anti-corrosion coatings for steel pipes
There are many kinds of steel pipe anti-corrosion coatings, and their properties and uses are different. The correct selection is very important for the anti-corrosion effect and service life of the coating. When choosing, you should consider: 1. The properties of the surface ...Read more -
What is the difference between 2205 duplex stainless steel pipe and 304 stainless steel pipe
1. Compared with 304 stainless steel pipe, the advantages of duplex stainless steel are as follows: (1) The yield strength is more than double that of ordinary austenitic stainless steel, and it has sufficient plasticity and toughness required for forming. The wall thickness o...Read more -
Introduction to the production steps of spiral steel pipe
How to produce all kinds of spiral steel pipes from a piece of steel? (1) Conduct various inspections on raw materials. Raw materials generally refer to strip steel coils, welding wires, fluxes, etc. Before putting into use, they must go through strict physical and chemical te...Read more -
Large-diameter steel pipe connection method and cleaning method
Cleaning method of large-diameter steel pipe: 1. Spray blasting and de-rusting: the high-power motor drives the blades to rotate at high speed, so that steel sand, steel shot, iron wire segment, minerals, and other abrasives are sprayed and projected on the surface of the stee...Read more -
Processing technology and inspection steps of straight seam steel pipes
The welding current in the swing welding of the straight seam steel pipe is slightly larger than that of the traditional welding method; secondly, the elongation of the tungsten electrode in the swing welding of the straight seam steel pipe is determined according to the wall ...Read more -
How to judge the quality of spiral steel pipe
1. From the surface of the spiral steel pipe to see whether the production process of the spiral steel pipe is exquisite. Generally, research and analysis of spiral steel are required, and the section of fake and inferior spiral steel pipes is oval. The reason is that the manu...Read more -
Stainless steel pipe surface finish grade
Original surface: NO.1 surface subjected to heat treatment and pickling treatment after hot rolling. Generally used for cold-rolled materials, industrial tanks, chemical industrial equipment, etc., the thickness is thicker from 2.0MM to 8.0MM. The stainless steel pipe processi...Read more -
Why are large-diameter steel pipes mostly welded with steel
1. The use of large-diameter stainless steel can be divided into oil well pipes (casing pipes, oil pipes, and drill pipes, etc.), pipeline pipes, boiler pipes, mechanical structure pipes, hydraulic prop pipes, gas cylinder pipes, geological pipes, chemical pipes (high-pressure...Read more -
Which environments are large diameter steel pipes suitable for
1. Petrochemical: Crude oil, refined oil, petrochemical raw material, and finished product delivery pipes and oilfield pipe network. 2. Natural gas: submarine and onshore long-distance pipelines; gas pipelines at gas receiving stations; gas fields and urban natural gas pipelin...Read more
