304 304l 316 316l Oval Steel Pipe 25mm Diameter
304 304L 316 316L 25mm Diameter Shaped Stainless Steel Pipe
Special shaped seamless steel pipe is the general name of seamless steel pipe with other section shapes
except circular pipe. According to the different shape and size of steel pipe section, it can be divided into equal
wall thickness special-shaped seamless steel pipe (code D), unequal wall thickness special-shaped seamless
steel pipe (code BD) and variable diameter special-shaped seamless steel pipe (code BJ).
