Carbon steel pipe elbow

Carbon steel pipe elbow

Carbon Steel Pipe Elbow is to change the direction of the metal Pipe Fittings. Connections are threaded and welded. Angularly points, 45 ° and 90 ° 180 ° three most commonly used, according to project needs in addition also include other non-normal 60 ° angle bend. Elbow materials cast iron, stainless steel, alloy steel, malleable iron, steel, nonferrous metals and plastics. Way tube connection are: direct soldering (the most common way) flange connection, hot melt connection, fused connection, threaded connections and socket-type connections. In accordance with 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.

Carbon steel can be divided into 10 # 20 # A3 Q235A 20g Q345B 20G 16Mn ASTM A234 ASTM A105 st37 ASTM A403, etc.
Raw materials for the production of these materials can be called Carbon Steel Elbow bend

90 ° steel elbow
Divided by the angle: 45 °, 90 °, 180 ° three common elbow, and another project needs, you can special order as 60 ° or any other angle.
Connection with the carbon steel pipe: Welded, flanged, threaded, socket connections form.
The process according to the form can be divided into: welding elbow, pressing elbow, casting elbow.
Purpose: to connect two pipes, to change the direction of the tube, the 45 ° and 90 ° or 180 ° direction or the other angle turn.
Manufacturing standards: GB, American Standard, the Japanese standard, German standard, the Russian standard.

The basic process of carbon steel elbow is: First welding a polygonal cross-section polygonal ring shell or shell closed at both ends of the polygonal sector, washed over the internal pressure of the medium, the pressure applied within the inner cross-section under Pressure polygon gradually become round, eventually becoming a circular ring shells. If necessary, a circular ring shell can be cut four or six 90 ° elbow 60 ° elbow or other specifications of the elbow, the process for the manufacture of bend in any ratio greater than 1.5 times the diameter of the inner diameter and elbow specifications large elbow, is an ideal method of manufacture of large carbon steel elbow.

The advantage of the carbon steel elbow production process mainly in the following aspects:
(1) without tube as raw materials, saving pipe equipment and tooling costs, and the large diameter and wall thickness can be obtained at any of the relatively thin carbon steel elbow.
(2) the blank is flat or developable surface, thus cutting simple, easy to ensure accuracy, easy assembly and welding.
(3) Due to the above two reasons, it can shorten the manufacturing cycle, the production cost is greatly reduced. Because does not require any special equipment, it is particularly suitable for on-site processing of large carbon steel elbow.

(4) carbon steel elbow for petroleum, natural gas, chemicals, utilities, construction and boiler piping industry series.
