There are many materials for international flanges. Now the common materials in the market are forged steel, WCB carbon steel, alloy steel, stainless steel, chromium molybdenum steel, chromium molybdenum vanadium steel, molybdenum titanium, rubber lining and fluorine lining. No matter which kind you need, our company will be useful. However, do not choose companies without qualifications. Otherwise, they use waste steel or scrap steel to process flanges in the production of national standard flanges. Usually, this kind of steel is a waste material whose chemical composition and mechanical properties do not meet the standards.
What is more, they use private steel-making plant of black steel to produce France. This kind of private steel-making technology is old and cannot guarantee the mechanical properties and welding properties, In this way, it may be impossible to weld with the steel pipe when in use, or the steel itself may leak after welding with cracks, pores, etc. Therefore, if you want to buy national standard flanges, you must go to a regular manufacturer, and you must choose this kind of international flange in size, so as to avoid various problems in use. If the fund is limited and the second standard flange is selected, it is necessary to carefully observe and measure the flange size and detect its material to avoid being cheated.
