Large caliber elbow according to the Angle can be divided into 45 degrees large caliber elbow, 90 degrees large caliber elbow and 180 degrees large caliber elbow and other different Angle elbow. According to the material can be divided into carbon steel large diameter elbow, stainless steel large diameter elbow, alloy steel large diameter elbow. According to the radius of curvature can be divided into long radius large diameter elbow and short radius large diameter elbow. The main standard of large diameter elbow is national standard, electric standard, Sinopec standard, Marine standard, Japanese standard, American standard, etc. Large diameter elbow has the advantages of smooth inner wall, small heat medium flow resistance, acid and alkali resistance, long service life, easy installation and so on.
Large diameter welding elbows are made of the same steel as the pipes to be joined in order to facilitate welding. That is, all pipe fittings should be disposed of on the outside, and the oxidized iron sheet on the inside and outside should be sprayed off by sandblasting, and then coated with anti-corrosion paint. This is not only for export demand, but also for domestic transport to avoid corrosion and oxidation, to do this work. As for small pipe fittings, such as export, it is required to make wooden cases, about 1 cubic meter. The number of elbows in such cases may not exceed 1 ton. The specification agrees to set, that is, a large set of small, but the total weight usually cannot exceed 1 ton. As for large items, it is necessary to pack them individually, like 24 ". The other is the packaging symbol, symbol is to indicate the scale, steel number, batch number, manufacturer. The pipe fittings should be stamped with steel and accompanied by packing list and warranty. Above we briefly introduce the Angle and packaging of large caliber elbow and small elbow.
