The welding rod should be kept dry when used, so as not to increase the carbon content of the weld and affect the welding parts and the use of function.  After welding hardening is larger, easy to crack, using the same welding rod welding, preheating above 300℃ and about 700℃ after welding slow cooling treatment, welding parts can not be post-welding heat treatment, should choose chromium nickel stainless steel electrode.  In order to improve the corrosion resistance of the stamped elbow pipe, the welding is better, the use of similar stainless steel electrode, need to preheat more than 200 degrees Celsius and about 8000 degrees Celsius after welding tempering, welding parts can not be heat treatment, should choose chromium nickel stainless steel electrode.

Stamped elbow pipe is resistant to air, steam, water and acid, alkali, salt and other chemical corrosion.  In the use of pipelines, the steel that is resistant to the corrosion of weak corrosive medium is often called stainless steel stamping elbow, and the steel that is resistant to the corrosion of chemical medium is called acid resistant steel.  Due to the difference in chemical composition, the former is not resistant to chemical medium corrosion, while the latter generally has rust resistance.

Stamped elbow fittings are easy to manufacture and form pipe fittings to meet the needs of architectural and structural designers. All metals react with oxygen in the atmosphere to form an oxide film on the surface.  The iron oxide formed on ordinary carbon steel continues to oxidize, expanding the corrosion and eventually forming holes.  The surface of carbon steel can be secured by electroplating with paint or oxidization-resistant metals such as zinc, nickel and chromium, but, as is known, this protection is a thin film.

 Stamping elbow manufacturers mainly produce a variety of different types and angles of stamping elbow pipe, carbon steel elbow, alloy steel elbow, stainless steel elbow, equal diameter tee, reducing tee, eccentric size head, concentric size head, pipe cap, head, flange, steel pipe and other pipe products.  All users who need the above pipe fittings products come to our company to visit and consult.  Our sales staff will introduce each user slowly.  To provide new and old users with excellent pipe products and services.
