Carbon Steel Seamless Pipe Bending

The serpentine bend pipe belongs to the special difficult pipe fitting. The serpentine bend pipe can be divided into cold and hot stewing.

  • Details

The serpentine bend pipe belongs to the special difficult pipe fitting. The serpentine bend pipe can be divided into cold and hot stewing. Generally small and medium pipe diameter bending can be obtained by cold bending. Big pipe diameter needs hot bend.

The Basic Information:

Product

Mainly used for bending colored or black metal pipes, suitable for building materials, shipbuilding, chemical industry, metallurgy, boilers and heavy machinery manufacturing departments. Products are mainly used for building circular steel structure, tunnel support, the roof beam bending, the subway engineering, aluminum doors and Windows, ceiling, cylindrical inner frame, balcony railings, shower door, production lines, rail, fitness equipment and other industries. Intermediate frequency bend pipe is widely used in pipeline prefabrication in electric power, petroleum, chemical industry, navigation, nuclear industry and other engineering fields. Intermediate frequency bend is stay in steel pipe bending part set in the process of induction coil, mechanically pivoted arm stuck pipe head, zhongtong into the intermediate frequency induction coil current heating tube, when the steel tube temperature to the plastic state, after the steel pipe end with mechanical thrust forward, bending, bending of making steel pipe section with coolant cooling rapidly, so that heating, while advancing, bending, while cooling, constantly to bend pipe bending.

Process

By using this process, the small radius (R approximately D) and the thin wall (t/D approximately 0.015) 180 elbow with uniform wall thickness can be obtained, which cannot be realized by other pipe bending processes. Medium frequency tube bending machine USES medium frequency induction heating to bend the workpiece under the condition of local heating. Compared with the general cold pipe bender, not only does not need a complete set of special die, but also the machine volume only accounts for 1/3 ~ 1/2 of the same specification of cold pipe bender. Medium frequency hot bend pipe technology is one of the most economical and effective bending pipe technology.

Features of medium frequency pipe bender:

By using this technology can be in the same horn mandrel last push to produce the same caliber of 45 ° and 90 °, 180 ° bend bend Angle, high production efficiency.

Implementation standards: gbt8163-1999, gbt8162-1999, ASTM A106A53 gr.b, API 5L gr.b, JIS G3456 STPT42, etc.

Material: A234 WPB, A105N, TP304, TP316, 304, 304L, 316, 316L, 3021, etc.

Accessories

Seamless pipe fittings series: 45 °, 90 °, 180 ° long and short radius elbow, such as diameter, reducing tee, four-way, concentric and eccentric reducer, pipe cap, S/u-shaped bend, SO flat welding flange, butt welding flange WN, blind flange BL, SW socket flange, threaded flange TH and plug-ins and other accessories.
