Carbon steel bending elbow produced by Taituo: small-diameter metal bends are obtained by bending, then this small-diameter metal bend is called bending elbow. The simmering bend needs to be explained separately: simmering bend refers to the processing of pipes into bends, generally refers to metal pipes for hydropower specialty and electrical PVC threading pipes; Simmer bend: refers to metal bends of water supply and drainage specialty, and bends of small diameter can be obtained by simmer bending; Simmer elbow: small-diameter metal elbow is obtained by simmering and bending small-diameter metal, then this kind of small-diameter metal elbow is called simmering elbow, which is divided into two types according to whether there are segments: segment mandrel head and segment mandrel head. The manufacture of the segmented mandrel is complicated, the cost is high, and the service time is long. The non-segment mandrel is simple to manufacture and low in cost, but the front end wears quickly.
The detection technology is advanced. Faced with the trend of economic globalization, we will, in the spirit of dedication, credibility and innovation, mold corporate culture with elite teams, improve product quality with corporate culture, promote the development of enterprise groups with hard work and hard work team spirit, and follow the business philosophy that quality leads to market and innovation leads to development. In the future development, we will persevere and earnestly perform our duties.

No matter what kind of machinery and equipment and pipelines, most of them are bent pipes, which are mainly used for oil transportation, gas transportation, infusion, etc. In pure bending, the outer arm wall of the middle layer is thinned by tensile stress 1 under the action of external force distance m, and the inner compressive stress. The cross section of the tube is changed by the resultant force N1 and N2. Based on this factor, RX and SX are the main reasons for the quality decline of bent pipes. Therefore, in GBJ235-82, RX values under various pressure levels and the thinning amount on the outside are clearly specified, so as to control the values of RX and SX and ensure the quality. As mentioned in the previous article, when bending, the outer side of the material is pulled, while the position of the neutral axis under internal pressure is different from the bending method. When working in top bending (compression bending), the neutral axis is about 1/3 away from the outer wall, and when working in rotary bending (back bending), the neutral axis is 2/3 away from the outer wall. Therefore, it is beneficial to use rotary bending method for bending thin-walled pipelines.
Pipe benders can be roughly divided into numerical control pipe benders, hydraulic pipe benders, etc. Purpose of pipe bender: Hydraulic pipe bender is mainly used for laying and repairing pipelines in electric power construction, public railway construction, boilers, bridges, ships, furniture, decoration, etc. It has the advantages of multiple functions, reasonable structure, simple operation, convenient movement, installation, etc. This machine not only has the function of bending pipe, but also can use the oil cylinder as a hydraulic jack. Compared with numerical control bending pipe equipment, it has the characteristics of low price and convenient use, occupying the leading product position in the domestic pipe bender market. The numerical control pipe bender can bend pipes with one bending radius (single mode) or two bending radii (double mode) in a cold state, and is widely used for bending various pipe fittings and wires in industries such as automobiles, air conditioners and the like. Pipe benders are mainly used for plastic forming of pipes. The bending pipe is made of materials such as cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metal and plastic, etc. and the process flow of hot bending pipe. after the straight pipe is fed, an induction ring is sleeved on the part of the steel pipe to be bent by a bending pipe pushing machine, the pipe head is clamped by a mechanical rotating arm, and a medium-frequency current is introduced into the induction ring to heat the steel pipe. when the temperature of the steel pipe rises to a plastic state, the steel pipe is pushed by mechanical thrust at the rear end of the steel pipe to be bent, and the bent steel pipe part is rapidly cooled by coolant, so that the bent pipe is continuously bent out while heating, pushing, bending and cooling.
The pipe is bent by using a complete set of bending dies, and is divided into two processes of cold heating and hot pushing.
