Welded pipe production line needs a lot of equipment to help production. Here are two of the equipment: one is the pipe end flat-end chamfering machine, the other is the hydraulic testing machine. First of all, let's talk about the pipe end flat-end chamfering machine, the pipe end cut by the cutting machine will generally leave some notch defects and burrs, in order to meet the follow-up process and user requirements for the groove. It is necessary to trim the burr and the inner and outer edges of the pipe end. The flat-end chamfering machine is the equipment used for milling the two ends of the welded pipe to make it flat and chamfered. It is composed of steel pipe feeding device, steel pipe cl/ing device, tool holder, follow-up device, transmission device, frame body and so on. The working process of the flat-end chamfering machine can be carried out automatically and continuously and controlled automatically.

Hydraulic test is the main welded pipe equipment in welded pipe production. At present, the working process of the hydraulic testing machine used in welded pipe production is as follows: feeding, cl/ing, water filling, pressurization, pressure keeping, pressure relief and discharge. The process also constitutes the basic action cycle of the test tube hydraulic press. Modern hydraulic testing machines are controlled by PLC, so that each working process can be completed automatically, and the parameters of the test results can be recorded automatically. According to the seal form, it can be divided into radial seal and end seal. The radial seal is a sealing ring matched with the inner or outer diameter of the welded pipe, and the sealing ring expands under pressure to achieve the purpose of sealing the pipe wall. Its advantages are that the steel pipe is easy to cl/ and pull out, the sealing is reliable, the axial force of the steel pipe is small, and it is not easy to bend, but the structure of the sealing head is more complex, there are many specifications, and there is a test blind area at the end of the pipe. The end seal relies on the compression of the sealing material and the end of the pipe mouth to achieve the purpose of the pipe mouth seal. Its advantage is that the test structure is simple and universal, but it has higher requirements for the performance of sealing material, the ratio of oil-water pressure difference and servo control system.
