Austenitic stainless steel is softened by solid solution treatment. Generally, the stainless steel tube is heated to about 950-1150°C and kept for some time, so that carbides and various alloying elements are fully and evenly dissolved in austenite, and then quickly quenched and cooled. , carbon and

Thick-walled welded pipe is a hard-to-deform precipitation-strengthened nickel-based superalloy, which is similar in composition to the ЭИ929 alloy of the former Soviet Union, and has a high level of solid solution strengthening of alloying elements and precipitation strengthening of γ' phase. It ha

The importance of coated composite steel pipes for fire protection in industrial applications is becoming more and more obvious, but do you know the details about coated composite steel pipes? Let's take a look next.1. Hygienic, non-toxic, no fouling, no breeding of microorganisms, ensuring fluid qu

1. Select the appropriate connection method according to the caliber and the specific conditions of the pipelineA. Welding: According to the site progress, enter the installation at an appropriate time. Fix the bracket in advance, draw a sketch according to the actual size, and prefabricate the pipe

1. 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

During the forming process of the spiral steel pipe, the steel plate is uniformly deformed, the residual stress is small, and there is no scratch on the surface. The processed spiral steel pipe has greater flexibility in the range of diameter and wall thickness, especially when producing high-grade

In modern household water supply pipes, the corrosion resistance of water pipes is very important, because it means we can drink healthy and pollution-free drinking water. When PPR plastic pipes were promoted as tap water pipes, a test report from the Shanghai Disease Research Institute showed that

1. The premise must be polishedThe galvanized layer at the weld must be polished off, otherwise, bubbles, trachoma, false welding, etc. will occur. It will also make the weld brittle and reduce rigidity.2. The welding characteristics of galvanized steelGalvanized steel is generally coated with a lay

Steel bending pipe processing and forming process1. Die forging. For socket welding and threaded tees, crosses, elbows, and other small pipe fittings, the shapes are more complicated and should be manufactured by the die forging process, and the die forging blanks should be rolled profiles, such as

There are significant differences between straight seam steel pipes and steel pipes. I believe that many people must think that the two are similar in terms of usage and performance. Straight seam steel pipes are higher than steel pipes. The better types sold in the market are electric welded steel
