Gas plastic coated steel pipe performance introduction
Plastic-coated steel pipe manufacturing process and others: it can be used under harsh conditions and has a long-term anti-corrosion life. Heavy-duty anti-corrosion coatings can generally be used for 10 or 15 years in chemical atmospheres and marine environments, even in acid and alkali, salt, an...Read more -
Why 316L stainless steel pipe fittings have better corrosion resistance
316 stainless steel is a type of molybdenum-containing stainless steel. Due to the molybdenum in the steel, the overall performance of this steel is better than that of 310 and 304 stainless steel. Under high-temperature conditions, when the concentration of sulfuric acid is lower than 15% and hi...Read more -
Preparations before connection of plastic-coated steel pipes

What is the difference between oil casing and oil drill pipe
There are two main differences between oil casing and oil drill pipe: 1. Different uses; 2. Different materials. Oil casing is a steel pipe used to support the walls of oil and gas wells to ensure the normal operation of the entire oil well after the drilling process and completion. Each well use...Read more -
Welding treatment of thick-walled spiral steel pipe
Thick-walled spiral steel pipe is a method of arc welding under the flux layer, which is formed by using the heat generated by the arc burning between the flux and the welding wire under the flux layer, the base metal, and the molten wire flux. During use, the principal stress direction of the th...Read more
