Stainless steel butt welding elbow installation and maintenance?

The installation and maintenance of stainless steel butt welding elbows and this video of soldering stainless steel with electric iron. If the welding structure has a little strength, it can be heated by flame. The heating tool is sprayed with WE53 special liquefied gas porous. oxygen. 2) It can be welded with high silver VOD203 welding wire. This welding has good mobility, and the defect is uniform cost. This is also the most widely used. When welding stainless steel, you need to use VOD201-F auxiliary solder paste. welding.

3) WE46 special solder stamping elbow welding which can replace high silver wire welding. The advantages of stamped elbows are seamless. The manufacturing process of stamped elbows is to first weld a polygonal ring shell with a polygonal cross section or a polygonal fan-shaped shell with closed ends. Under pressure, the cross-section gradually changes from a polygon to a circle, and finally becomes a circular ring shell. According to requirements, a circular ring shell can be cut into 4 90 elbows or 6 60 punched elbows or other standard punched elbows.

Stainless steel butt-weld elbow installation and maintenance marine standards, Japanese standard, American standard, etc. Stainless steel butt-weld elbows have the advantages of inner wall lubrication, low resistance to heat medium activity, acid and alkali resistance, long service life, and easy installation. The wear of the 90-degree hot-pressed elbow has always been a factor that affects safe and civilized production. Large-diameter carbon steel elbow manufacturers continue to develop with the development of scientific skills and continuous innovation of materials. Casting stones, casting steel, alloys, centrifugal casting Composite ceramics and other information.

Among them, the aluminum oxide ceramics lined with pipes have high wear resistance, high hardness, oxidation resistance, good corrosion resistance and high high and low temperature resistance performance. Most of the equipment imported from abroad use this carbon steel elbow. For example, Huaneng Dalianfa, Huaneng Yueyang Power Generation, Guohua Sanhe Datang Tuhe Susu carbon steel bends are fitted with wear-resistant ceramics. Has become an application * extensive wear-resistant materials, accounting for about 80% of the international special ceramic market share (wear-resistant materials) The threshold of hot pressing elbow skills is very high. Now it mainly depends on imports.
