45 ° elbow, 90 ° elbow, 180 ° bend in the piping system, the piping is to change the direction of the elbow pipe. By angle points, 45 ° and 90 ° 180 ° three most commonly used, according to project needs in addition also includes other non-normal 60 ° angle bend. Elbow materials are cast iron, stainless steel, alloy steel, malleable iron, steel, nonferrous metals and plastics. Way connected with the pipe are: direct welding (the most common way) flange connection, hot melt connection, fused connection, threaded connections and socket type connections. According to the production process can be divided into: welding elbow, pressing elbow, push the system elbow, casting elbow. Other names: 90 degree elbow, right angle bend, bend, etc. love. 45 degree carbon steel elbow is the most commonly used product specifications elbow, I plant the 45 degree carbon steel elbow product has the following characteristics: a long-term pressure resistance, low thermal shock resistance, environmental protection, recyclability. Elbow is commonly used in a plumbing installation connecting pipe for connecting the pipe bend for changing direction of the pipe. Other names: 90 ° elbow, right angle bend, stamping elbow, pressing elbow, elbow mechanism, welding elbow. Purpose: connect two identical or different nominal pipe diameter, so the pipeline for 90 °, 45 °, 180 ° and various degrees of turn. Bend radius less than or equal to 1.5 times the diameter of the elbow are greater than 1.5 times the diameter of the elbow are 45 degrees elbow stainless steel is one of the main varieties of quality products, our factory elbow, 45 degree elbow stainless steel distinguished Elbow mainly of different materials, the chemical composition of its surface contained elbow will remain for a long time will not rust, will not corrode. 45 degree elbow is mainly used for stainless steel pipes installed in a connecting pipe for connecting the pipe bend. Connect two identical or different nominal pipe diameter, so the pipeline for 45-degree turn. According to standard production can be turned into: 1 to produce a standard can be divided into national standard, the ship standard, electricity standard, water standard, American standard, German standard, Japanese standard, the Russian standard and so on. 2. production methods can be divided into push the system, pressing, forging, casting and so on. Stainless steel elbow characteristics: strength, toughness index is the best kinds of steel, the most prominent advantage is anti-corrosion, chemical and paper corrosive applications must use stainless steel. 90 degree elbow is one of the main high-pressure high-quality varieties of our products elbow, 90 degree elbow high pressure is used to carry out a high-pressure pipe fittings corner turn different angles. All fittings in high pressure piping system used in the largest proportion, about 80%. General thickness of the high-pressure elbow 90 degrees elbow to be thicker than normal, or high pressure material strength than ordinary strength elbow higher. There butt and socket weld and threaded connection three ways. Implementation of standards GB / T12459-2005, GB / T13401-2005 and so on. 90 degree elbow material commonly used high-pressure high-quality steel, carbon steel, stainless steel or alloy steel, high pressure elbow can withstand high pressure in a variety of high-pressure pipeline and the pipeline can withstand the corrosive fluid. 180 degree carbon steel elbow is one of the main products of our plant varieties elbow, 180 degree carbon steel elbow elbow is the most commonly used product specifications, I plant the 180-degree bend steel products have the following features: long-term pressure resistance, low thermal shock resistance, environmental protection, recyclability. Elbow is commonly used in a plumbing installation connecting pipe for connecting the pipe bend for changing direction of the pipe. Other names: 90 ° elbow, right angle bend, stamping elbow, pressing elbow, elbow mechanism, welding elbow. Purpose: connect two identical or different nominal pipe diameter, so the pipeline for 90 °, 45 °, 180 ° and various degrees of turn. Bend radius less than or equal to 1.5 times the diameter of the elbow are greater than 1.5 times the diameter of the bend belong. Sch140, Sch160, XXS.
