Seamless carbon steel elbow 180° elbow manufacture

Seamless carbon steel elbow 180° elbow manufacturer

The 180° elbow is a metal pipe fitting that changes the direction of the carbon steel pipe.Connection mode: wire buckle and welding.According to the Angle points, there are 45° and 90° 180° commonly used three, in addition, according to the needs of the project also includes 60° and other abnormal Angle elbow.Elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metal and plastic, etc.Direct welding is also a common way to connect pipes, such as normal connection, hot melt connection, electric melt connection, thread connection and socket connection.According to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, other names: 90° elbow, right Angle bend, etc.A 180° elbow can be divided into a long radius elbow and a short radius elbow according to its radius of curvature.A long radius elbow refers to the outer diameter of the pipe whose radius of curvature is equal to 1.5 times, i.e., R= 1.5d.Short radius elbow refers to the radius of curvature is equal to the outside diameter, namely R= 1.5d. (D is the elbow diameter, R is the radius of curvature.D can also be expressed in multiples.)In terms of pressure grade, there are about 17 kinds of pipes, which are the same as the American standards. Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS.Sch80, Sch100, Sch120, Sch140, Sch160 and XXS, among which STD and XS are commonly used.According to the Angle of elbow, there are 45° elbows, 90° elbows and 180° elbows.Our company mainly produces elbow, small head (reducing pipe) and pipe cap.Tees, flanges, bends, etc.Welcome new and old customers to visit.

Seamless elbow: An elbow is a pipe fitting for a pipe bend.In all pipe fittings used in the piping system, it accounts for a large proportion, about 80%.Generally, different forming processes are selected for elbows with different materials or wall thickness.The jointless elbow forming technology commonly used by manufacturers includes hot pushing, stamping, extrusion and so on.

Hot push forming technology of hot push elbow is a process in which the blank on the mold is pushed forward by the common elbow pushing machine, core die and heating device, and heated, expanded and bent during the movement.Hot push bend deformation characteristics are based on volume before and after plastic deformation rule of metal materials determine the pipe diameter, pipe diameter bend diameter, through the core module and control the deformation of the process, make the inner arc compressed metal flow, the compensation to other parts of the thinned by hole diameter, wall thickness uniform Angle is obtained.Hot push elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, suitable for mass production, so it has become the main forming method of carbon steel, alloy steel elbow, and also used in the forming of stainless steel elbow of some specifications.

The heating methods in the forming process include intermediate frequency or high frequency induction heating (the heating ring can be multi-ring or single-ring), flame heating and reverberatory furnace heating. Which heating method is adopted depends on the requirements of the forming products and the energy situation.Stamping forming: Stamping forming elbow is early used in the mass production of seamless elbow forming process, in the common specifications of elbow production has been heat push method or other forming technology to replace, but in some specifications of elbow due to the small number of production, too thick or too thin wall.Products are still in use when there are special requirements.The elbow is formed by the tube blank with the same outer diameter as the elbow, which is directly pressed in the die by the press.

Our company mainly produces seamless elbow,seamless carbon steel elbow, tee, large and small head, pipe cap, elbow and other types of pipe fittings.
