ASTM A249 stainless steel welded pipe for condenser, heat exchange&Boiler
Advantage of stainless welded pipes
Due to product characteristics of high wall thickness uniformity, smooth and delicate surface,high temperature resistance, hight pressure resistance,corrosion resistance,long service life,energy saving and environmental protection and so on. The stainless steel welded pipe gradually tends to expand the scope of application and to enter may fields in which seamless tube could undertake in the past.
