How to correctly judge the thickness of stainless steel welded pipe
How to correctly judge the thickness of the stainless steel welded pipe refers to the wall thickness of the pipe. Tell everyone that the wall thickness of the stainless steel welded pipe will be attached to the pipe under normal circumstances. Customers can know the thickness ...Read more -
How to detect the corrosion performance of steel flanges
The use of steel flanges in industrial structural parts is mainly to improve the connection and keep the pipelines sealed without leakage. However, many steel flanges will corrode and age after being used for some time, thus losing their tightness. Therefore, it is very necess...Read more -
Horizontal fixed welding of thick-walled stainless steel pipes
Thick walled stainless steel pipe is a hollow long strip of steel, which is widely used as a pipeline for transporting fluids, such as oil, natural gas, water, gas, steam, etc. Stainless steel pipes are lighter in weight when they have the same bending and torsional strength. ...Read more -
Wall Thickness Accuracy and Straightening Method of Straight Seam Steel Pipe
The control of the wall thickness of the straight seam steel pipe is a difficult point in the production of steel pipes. At present, the methods of straight seam steel pipe manufacturers in the production of wall thickness accuracy generally include: 1. Tube billet heating: th...Read more -
What inspections do submerged arc steel pipes need to go through after production
In the process of producing submerged arc steel pipes, the temperature must be strictly controlled, to ensure the reliability of welding. If the temperature is too low, it may cause the welding position to fail to reach the temperature required for welding. When most of the me...Read more -
How to avoid rusting of precision stainless steel pipe fittings
1. Do not contact other metals, because stainless steel pipe fittings will be rusted by the attachment of dissimilar metals, such as screws, etc. Although it is not serious at the beginning, if you wipe it with a cloth and a neutral detergent, you will see rust. 2. Another fac...Read more -
Description of the length and mechanical properties of large-diameter steel pipes
The main processing methods of large-diameter steel pipes are: forging steel: a pressure processing method that uses the reciprocating impact force of a forging hammer or the pressure of a press to change the blank into the shape and size we need. Extrusion: It is a processing...Read more -
The difference between submerged arc welded spiral steel pipe and straight seam high frequency welded steel pipe
The submerged arc welding spiral steel pipe uses continuous welding wire as the electrode and filler metal. During work, a layer of granular flux is covered in the welding area. The arc of the large-diameter spiral pipe burns under the flux layer to melt the end of the welding...Read more -
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
