Approved Stainless Steel 304 Elbow Manufacturer In China and ASTM A403 WP 304 Elbows Material Specification.
Elbow is a very important pipe fitting that is often used to change direction in piping systems. The function of an elbow is to change the direction or flow in a piping system. Whenever a pipe elbow is used, it must specify the type (45 or 90 degrees) and the radius (long or short) to determine the nominal size. Grades 304/304L (UNS S30400/S30403, EN 1.4301/1.4307) are the most widely used austenitic stainless steels. The 304L grade is a low carbon 304 and it is common practice for 304L to be dual certified for both 304 and 304L.
At the same time, it is corrosion resistant and helps prevent contamination of the internal fluid. Various industries trust this standard because it describes safety and quality. Stainless steel 304 elbows are made of high grade stainless steel to help withstand fluid pressures at moderate and high temperatures. We are one of the top manufacturers of ASTM A403 WP 304 Stainless Steel Long Radius Elbows, covering the standard for forged austenitic stainless steel fittings for a variety of pressure applications.
In addition to strength and corrosion resistance, the tighter radius of the durable 30 degree 304 elbow gives full flow unrestricted access compared to other types of fittings such as 45° ASTM A403 WP 304 elbows which block some amount flow due to their round shape design reducing overall efficiency within a system or pipeline set up. This can be advantageous as less drop in pressure will occur along with improved circulation for pumps/valves located downstream within long runs systems requiring higher velocity rates.
