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 -
What is the function of steel elbow
Steel elbows are pipe fittings that change the direction of the pipeline In the pipeline system, the steel elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three most commonly used ones: 45° and 90°180°. In addition, accordi...Read more -
What are the factors that affect the performance of steel pipes
Factors that can degrade steel piping materials or affect their functionality include pH, soil and water resistivity, abrasion resistance, chloride, sulfate or acid corrosion, fire resistance, crack growth and oxidation of thermoplastics, and steel Electrochemical corrosion. T...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 -
About the characteristics and uses of straight seam steel pipes
Characteristics of straight seam steel pipes: Straight seam steel pipes generally refer to the use of special processes to carry out anti-corrosion treatment on ordinary steel pipes, so that the steel pipes have excellent anti-corrosion capabilities, and are generally used for...Read more -
Methods for preventing or slowing down the corrosion of petrochemical steel pipelines
1. Adapt measures to local conditions: Reasonably select pipeline building materials, and select different types of materials according to different conveying media and environmental conditions. 2. Steel pipe with external DC power supply: the metal of the pipeline that was or...Read more -
Straight seam welded pipe anti-rust maintenance and inspection methods
The production process of straight seam welded pipe is simple, the production efficiency is high, the cost is low, and the development is rapid. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe, and the welded pipe with a la...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
