彎頭在管路系統(tǒng)中，彎頭是改變管路方向的管件。按角度分，有45°及90°180°三種最常用的，另外根據(jù)工程需要還包括60°等其他非正常角度彎頭。彎頭的材料有鑄鐵、不銹鋼、合金鋼、可鍛鑄鐵、碳鋼、有色金屬及塑料等。與管子連接的方式有：直接焊接（最常用的方式）法蘭連接、熱熔連接、電熔連接、螺紋連接及承插式連接等。HDPE管www.jsyzhsff.com,按照生產(chǎn)工藝可分為：焊接彎頭、沖壓彎頭、推制彎頭、鑄造彎頭等。其他名稱：90度彎頭、直角彎、愛而彎等。

　Elbow in the piping system, the elbow is change the pipeline direction pipe. According to the angle, 45 °and 90 °180° three kinds of the most commonly used, and according to the need of the project also includes 60 °and other abnormal angle elbow. Elbow material of cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metal and plastic. Connect with the pipe in the way: the direct welding ( most commonly used modalities ) flange connection, hot melt connection, welding connection, connecting thread and socket type connection. According to the production process can be divided into: welding bend, stamping elbow, elbow, Elbow push system of casting. Other names: 90 degree elbow, right angle bend, love and bending.
