Things to note when installing stainless steel pipe fittings
The use of flat joints for stainless steel pipe fittings requires high pipe quality, as well as the outer diameter ovality, wall thickness, and physical properties of the rubber ring of cast iron drainage pipes. Since the flat joints have poor watertight performance conditions...Read more -
The difference between fixed length and indefinite length of Q235A spiral steel pipe
The length of steel pipes for pipelines, but for the convenience of users, when the steel pipes are sold at any time, the Q235A spiral steel pipes are produced with variable length pipes within the standards, but when the actual order is made, the standard length steel pipes a...Read more -
Precautions for using stainless steel flanges
Although stainless steel flanges have unique advantages in terms of material, no matter how good they are, they still need to be used with caution, so that they can be used for a longer period. So what should you know about the specific use of stainless steel flanges? 1. To pr...Read more -
Performance comparison between spiral steel pipe and straight seam steel pipe
1. Welding process: In terms of the welding process, the welding methods of spiral steel pipes and straight seam welded pipes are the same, but straight seam welded pipes inevitably have many T-shaped welds, so the probability of welding defects is greatly increased, and the w...Read more -
Precautions for handling and storing stainless steel pipe at the construction site
After thin-walled stainless steel pipes are packaged and bundled, they should be stored in a dry and clean environment without corrosive gases to avoid disorderly stacking with other items. Because the surface of stainless steel is relatively smooth and bright, and it is a met...Read more -
Classification and corrosion protection of oil casing
Petroleum casing can be roughly divided into one and surface casing according to different usage methods. 2. Intermediate casing. 3. Production of casing. 4. Drilling casing. The main purpose of surface casing is to suspend and support subsequent layers of casing through the c...Read more -
Precautions for construction of plastic-coated steel pipes
1. Plastic-coated steel pipes are strictly prohibited from being thrown or violently impacted during transportation, loading and unloading, and construction on construction sites; 2. Plastic-coated steel pipes should not be buried in reinforced concrete structural layers; 3. T...Read more -
The main production process of large diameter straight seam welded pipe
1. Plate exploration: After the steel plate used to manufacture large-diameter submerged arc welded straight seam steel pipe enters the production line, the full plate ultrasonic inspection is first performed; 2. Edge milling: double-sided milling of the two edges of the steel...Read more -
Method for preventing quenching cracks of medium and high carbon low alloy steel pipes
(A) If the entire steel pipe is cooled to the martensitic transformation stop temperature (Mf point) or lower by strong water quenching, quenching cracks will occur with high probability. (B) Since the cracks at the time of quenching cracking extend substantially in the axial ...Read more
