30 degrees bend pipe: pipe installation in a common connection pipe for connecting pipe bend.
Other names: 90 degree bend, bend, bend and love etc..
Use: connect two same nominal diameter of the pipe, the pipe to make a 90 degree turn. The classified material of carbon steel elbow, cast steel elbow, alloy steel elbow, stainless steel elbow, copper elbow, elbow Aluminum Alloy etc.. Production methods can be divided into push bend, stamping elbow, elbow, elbow and other casting forging. Makes the standard can be divided into standard, standard, water, electricity American Standard, German standard, Japanese standard, Russian standard, etc.. Of course, the tube is processed into a 30 degree bend pipe, generally refers to the metal pipe and electric power professional PVC threading pipe type; thus the elbow is many, orders are taken when the regular order representation: such as "LR STD 90o 8", said the long radius, pressure rating to STD, 90o 8 "elbow; again," SR XS 45o "said the 4 short radius, pressure rating to XS, 45o 4" elbow. The above is about the classification of elbow.
30 degrees: refers to the metal elbow bend drainage professional, small diameter can be obtained by bending the elbow; elbow in the pipeline project, mainly used for pipeline flange connection. The need to connect the pipe, flange mounted with a low-pressure pipe can use wire connecting flange, 4 kg more than the use of pressure welding flange. Between the two flange and sealing points, and then the bolt fastening. Different pressure flange with different thickness and the use of different bolt.
Cold and hot bending: general small and medium caliber elbow bending can be obtained; large diameter heat is required to bend. Bending processing generally refers to the scene.
Stamping elbow: the use of most of the engineering water supply system (especially large diameter) can buy finished elbow, stamping processing method, good product consistency.
Push bend process: in the late 80's contact with the medium frequency heating method of mechanical mould for inner tube + + steel elbow, but probably is not easy to control the wall thickness, rare application.
The classification method for 30 degree elbow pipe, according to minutes of its radius of curvature, and can be divided into long radius elbow short radius elbow. Long radius elbow refers to the pipe diameter of its radius of curvature is equal to 1.5 times, that is R = 1.5D. Short radius elbow refers to its radius of curvature is equal to pipe diameter, R = D. In the D welding elbow diameter, radius of curvature R. If divided by the pressure level to about seventeen, and the American Standard pipe is the same, are: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, and STD is one of the most commonly used XS two. According to the angle of bend, 45 degree elbow, 90 degree elbow and 180 degree elbow.
Production and sales of large enterprises in Cangzhou Deyang pipeline equipment manufacturing Co. Ltd., the leading products are three links, elbow, reducer, pipe cap, insulation pipe, flange, flange, carbon steel, alloy steel, stainless steel pipe factory, ASTM, DIN, DLT, HG, JB, JIS, MSS, SH, SY, ROCT and other production standards, non-standard products customized production.
