Realize automatic flaw detection and eddy current detection of tubing couplings
The oil industry is inseparable from various pipelines. For a long time, oil production plants have been troubled by the recycling of oil steel pipes, because a large number of oil pipes go directly into the well without inspection and treatment, and may break down or leak at ...Read more -
The difference between hot simmering steel bending pipe and cold simmering steel bending pipe
The process is as follows: After the straight pipe is cut, the induction coil is put on the part of the steel pipe to be bent by the bending machine, the pipe head is clamped by the mechanical arm, and the intermediate frequency current is passed through the induction coil to ...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 -
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
