Stainless Steel Pipe/Tube Grade 1.4301 ASTM A312 / ASME SA312-manufacture,factory,supplier from China

Difference between ANSI and ASME Flanges?The ANSI and ASME terms are most common in metal industries. But many people still don't know the exact difference between ANSI and ASME. They thought that both ASME & ANSI Flanges are the same and there is no difference between them. But that's not right. In this article, we clearly understand the difference between ANSI and ASME Flanges. ANSI and ASME Flanges are the standard flanges designed with specific rules and conditions stated by ASME and ANSI standards.

In most cases, there is no clear distinction between food grade and sanitary grade products. Generally (not necessarily) one of the requirements can be met, and the other can be met. The reason why it is divided into food grade and sanitary grade is that the direction of certification (standard source) is different.

Super Austenitic 904L stainless steel tubes are designed for corrosive environments. By optimizing chemical composition, super austenitic 904L stainless steel tube is a super austenitic stainless steel with low C content and high alloying. 904L super austenitic stainless steel tube blank was successfully developed by specific production process.

Basics on Choosing Stainless Steel GradeStainless steel is best known for its corrosion resistance, which makes it perfect for a huge variety of applications. There are a wide range of grades available within stainless steel, and these allow it to be useful in numerous different industries.At the same time, this means you have to have the know-how to select the proper grade for your next project. At Wasatch Steel, we’re here to help. Let’s look at some areas to consider when choosing stainless steel grade.FormabilityFor applications that need good formability, avoid the martensitic group.

The oxide film on the surface of stainless steel square tube is thin and dense, which is not easy to fall off. Mechanical cleaning is a common and effective means of stainless steel surface treatment. The iron oxide scale cleaning machine is mainly composed of steel brush roller, driving device, high-pressure water system, cooling water system and clamping device.Some preparations need to be done before welding of stainless steel square tube, which can improve the quality and efficiency of tubeline welding and the safety measures of welding workers.
