Stamping elbow has some corrosion the (oxidizing acids, organic acids, cavitation), heat and abrasion resistance. Typically used in power plants, chemical, oil, and other equipment and materials. Chromium stainless steel stamping elbow welded p oor, should pay attention to the welding process, heat treatment conditions and the appropriate choice of welding electrodes. Stamping elbow drug skin titanium calcium type low hydrogen type. Titanium calcium type can be used for AC-DC and AC welding penetration shallow, and at the same time easy to redness, it is stainless steel stamping elbow as much as possible using a DC power supply.

Steps / methods stamping elbow sclerosing larger cracks easily use different welding electrodes for welding, to ensure the quality of t he welding stamping elbow after welding. Using the same type of chromium stamping elbow welding electrodes must be carried out about 300 ° C above the preheating and post weld 700 ° C slow cooling treatment. Weldment can not post-weld heat treatment should be used chrome-nickel stamping elbow. In use, the different types of electrodes have different properties and characteristics, in use, in accordance with the corresponding need for selection, and to protect the quality of the welding stamping elbow.

Stamping elbow should be kept dry, titanium calcium type should be dried at 150 ℃ for 1 hour, low hydrogen type should be dried by 200-250 ℃ for one hour (not repeated drying or drug skin prone to cracking peeling) prevent the stainless steel stamping elbow drug skin sticky oil and dirt, to avoid causing increased carbon content and impact of the weldment quality stainless steel stamping elbow weld.Stainless steel elbow

To improve the corrosion resistance and weldability of the stamping elbow, the appropriate increase in the production of moderate stability elements Ti, Nb, mo, weldability than chromium stamping elbow. Preheat and post-weld above 200 ℃ and 800 ℃ tempered, using the same type of chromium stainless steel stamping elbow. Weldment is not heat-treated, you should use the chrome-nickel stainless steel stamping elbow.

Welding stamping elbow after heating will release carbide, carbide precipitation by repeated heating, carbide released stamping elbow will affect the performance and reduce the corrosion resistance and mechanical properties. The above is the need to pay attention to stamping elbow, you need to use, in accordance with the methods and matters to ensure good use of value and performance.sanitary pump

Stamping elbow with good corrosion resistance and oxidation resistance, and good to promote its use in different areas and promotion, widely used in chemical, fertilizer, petroleum, medical machinery manufacturing.

Stamping elbow is an elbow, widely used in different fields and industries and promote the app lication and popularization of varying degrees. Stamping elbow with plates of the same material of the pipe with a stamping die stamping into half a ring elbow, then two half-ring elbow group forming welding, stamping elbow welding in accordance with certain processes of production and processing . Below explain the precautions and methods of stamping elbow, in use strict attention, to ensure the quality and performance of the stamping elbow, it has a good life.
