The wide fitting equipment manufacturing co., LTD. Main production according to the requirements of customer satisfaction recognition bent pipe equipment, pipe bending equipment quality assurance, the price is low, long life and other advantages, the advantages of the above is the customer to choose the benefits of the wide fitting equipment co., LTD., bending equipment design is novel, simple and convenient operation, can also be automated production.  In the production and manufacture of bending equipment has many years of manufacturing experience, welcome new and old customers to inquire and order!  

Bending equipment mainly produces different types and caliber of bending pipe, can be made into any Angle of bending pipe.  According to customer's requirements, the bending equipment can be used in the bridge, petroleum, chemical Angle of all kinds of turning.  

The quality of bending equipment: in pure bending, the outer arm wall of the intermediate layer is thinned by tensile stress &1 under the action of the outer force distance M, and the inner side is subjected to compressive stress.  The resultant force N1 and N2 changes the cross section of the pipe. Based on this factor, RX and SX are the main reasons for the quality decline of the elbow. Therefore, GBJ235-82 clearly stipulates the RX value and the amount of thinning outside under various pressure levels, in order to control the VALUES of RX and SX, so as to ensure quality.  

2, the previous article has said that when bending the material outside the tension, the position of the inner pressure neutral axis is different from the bending method, in the top bending (compression bending) when the neutral axis is about 1/3 from the outer wall, in the rotary bending (back bending) work, the neutral axis is 2/3 from the outer wall.  Therefore, it is beneficial to use the method of rotary bending for thin - wall pipe bending.  

The bending machine produced by the company can be made according to customer requirements.  Our company welcomes customers from all over the world to visit our company and order!
