GOST 17375 Stainless Steel Ss321 Elbow Welded Elbow Od219 12X18h10t

Elbow is a kind of connecting pipe fitting commonly used in water heating installation. It is used to connect the pipe at the bend and change the direction of the pipe.Other names: 90 ° elbow, right angle elbow, Elbow, stamping elbow, pressing elbow, machine elbow, welding elbow, etc.Purpose: connect two pipes with the same or different nominal diameters to make the pipeline turn 90 °, 45 °, 180 ° and various degrees.Bending radius less than or equal to 1.5 times of pipe diameter belongs to elbow, and bending radius greater than 1.5 times of pipe diameter belongs to elbowA kind of connecting pipe fitting commonly used in pipeline installation, connecting two pipes with the same or different nominal diameters to make the pipeline turn at a certain angle, and the nominal pressure is 1-1.6Mpa.In a piping system, an elbow is a fitting that changes the direction of a run. According to the angle, there are three most commonly used types: 45 ° and 90 ° 180 °. In addition, 60 ° and other abnormal angle elbows are also included according to the needs of the project. The materials of elbows include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, nonferrous metals and plastics.The connection methods with pipes include: direct welding (the most commonly used method) flange connection, hot melt connection, electrofusion connection, threaded connection and socket connection. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow, etc. Other names: 90 degree elbow, right angle elbow, etc.ELBOWType(Long radius ,Short radius)15degree, 30 degree, 45 degree,90 degree, 180 degreeTechnicsSeamless Elbow, Welded ElbowSize1/2"-48"(DN15-DN1200)VarietiesSCH5,SCH10,SCH20,SCH30,STD, SCH40, SCH60,XS, SCH80, XXS,SCH100,SCH120,SCH140,SCH160StandredANSI B 16.9/ANSI B16.28/MSS SP43/MSS P75/JIS2311/JIS 2312/JIS2313/ DIN2615 /GB-12459/GB-T13401,Gost17375MateriaCarbon steel: ASTM A234 GR WPB , ST37.2 , ST35.8...Alloy steel: A234 WP5/WP9/WP11/WP22/WP91, A420 WPL6,                   A860 WHPY 42/52/60/65/70/80...Stainless steel: A403 WP304/TP304 , WP304L/TP304L , WP316/TP316 ,                           WP316L/TP316L, WP321/TP321 , WP310/TP310…..SurfactreatmentCarbon steel:Shot blasted, black painting, rust-proof oil, transparent oil,                           galvanizing,, hot galvanizingAlloy steel:Shot blasted, black painting, rust-proof oil,transparent oil, galvanizing,, hot galvanizingStainless steel: pickled,Polish Application FieldsChemical Industry /Petroleum Industry /Power Industry/Metallurgical IndustryBuilding Industry  /Ship-building Industry  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
