Hebei Hongwu Pipe Fittings Factory

Big Bend/*/3 Carbon Steel Big Bend Purchasing Power Plant Bend Pipe:
Bending radius: R, and R3 (use R equal to 3,,,,,,,, to represent the bending radius,
is the outside of the pipe diameter) can also be bent according to the angle proposed by the customer.
Bending angle: commonly used are, 3,,,, 3 and, it can also be bent according to the angle proposed by the customer.
Straight section length: The length of the straight section at both ends of the bent pipe is generally about 3-, and the length can also be customized according to customer requirements.
Execution standards: According to power station bends and steel bends, or according to standards or technical requirements proposed by customers.
Product usage: petroleum gas pipeline engineering, natural gas pipeline engineering, chemical plants, power plants, high-pressure pipelines in the chemical industry, water conservancy, etc.
Big Bend/*/3 Carbon Steel Big Bend Purchase Oil and Gas Pipe Bend:
The oil and gas pipe bend is a heating trap placed on the steel pipe, with a gap of about 10cm from the steel pipe on all sides, and the outside is slightly + , the inner side is slightly -. Heating width is approx. Heating width is approx. During the bending process, the strong wind is used to cool down the temperature, so that the specified heating width temperature is kept at the left and right when bending. In this way, the steel pipe itself is supported by the cooling round parts at both ends, so that the bending part is always carried out in a narrow width. , so as to achieve the effect of unchanged roundness or little deformation after the steel pipe is bent and formed.
Oil and gas pipeline elbows are mainly used to heat straight seam pipes and seamless steel pipes. They can be produced only after the effect is achieved through medium frequency heating.
Medium frequency induction heating pipe bending is an advanced pipe bending method. However, if the pipe bending process is improper, relaxation and damage to the metal structure of the pipe may occur. This damage manifests itself as a fine grain boundary crack, which has certain adverse effects on the mechanical properties and service life of the pipe. The heating range of medium frequency bending pipe is narrow, the temperature inside and outside the pipe wall is uneven, and the pipe is subject to sudden cooling and sudden heating during the bending process, which is its inherent weakness.
