In the piping system,the direction of the line pipe bend is to be changed.Elbow materials:stainless steel, alloy steel, cast iron can be calcined cast iron, carbon steel, nonferrous metal and plastic, etc. 1,Stainless steel, ASTM/ASME A403 WP 304-304 - l - 304 - h - 304 ln - 304 n ASTM/ASME A403 WP 316-316 l - 316 - h - 316 ln - 316 - n - 316 ti ASTM/ASME A403 WP 321-321 - h ASTM/ASME A403 WP 347-347 - h
2,Carbon steel, ASTM/ASME A234 WPB, WPC
3,Alloy: ASTM/ASME A234 WP 11-12-1 - WP WP WP 22 - WP 91-5 - WP WP911
4,Low temperature steel, ASTM/ASME A402 WPL3 - WPL 6
5,High performance steel: ASTM/ASME A860 WPHY 42-46-52-60-65-65
6,Cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon luo drain, PVC, PPR, RFPP (reinforced polypropylene), etc.
stainless steel pipe fitting plastic caps won't produce corrosion, pitting, corrosion or wear and tear.
1,Method to make division can be divided into pushing, pressing, forging, casting, etc.
2,By manufacturing standards can be divided into the national standard, the electric standard, water standard, American standard, Germany standard, Japanese standard, the standard and so on.
3,To differentiate material of carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon luo drain, PPC, etc
4,According to the radius of curvature points: can be divided into long radius elbow and short radius elbow
The purpose of the elbow:connect two of the same or different nominal diameter pipe,make the line for turning angle.Due to the elbow with good comprehensive performance,so it is widely used in chemical industry, building, water supply, water drainage, oil, light and heavy industry, freezing, sanitary, plumbing, fire protection, electric power, aerospace, shipbuilding and other infrastructure projects.
