水压试验机是焊接管的主要生产设备。目前，焊管生产中使用的是水压试验机，其工作过程是:进给、夹紧、进水、加压、加压、卸压、出压。
Hydrostatic testing machine is the main production equipment of welded pipe. At present, the hydraulic testing machine is used in the production of welded pipe, its working process is: feeding, clamping, water inlet, pressure, pressure, pressure relief, pressure.
流量是水压机的基本运动循环。现代水压试验机采用PLC控制，使各工作过程依次自动完成，并具有自动记录试验效率参数的功能。
Flow rate is the basic motion cycle of hydraulic press. The modern hydraulic testing machine is controlled by PLC, which makes each working process complete automatically in turn, and has the function of automatically recording the test efficiency parameters.
水压机依照径向密封和端面密封的密封类型可以分为两种,使用径向密封一起焊管内外密封圈,通过密封圈压缩扩张的过程来达到密封的目的,其好处是钢管夹和退出都很容易,密封好,钢管轴向力小,不容易弯曲,但封头结构相对复杂,并说明，管道测试盲区存在。
According to the sealing types of radial seal and end face seal, hydraulic press can be divided into two types. The radial seal is used to weld the inner and outer sealing rings of the pipe together. The sealing purpose is achieved through the compression and expansion process of the sealing ring. The advantage is that the steel pipe clamp and exit are easy, the sealing is good, the axial force of the steel pipe is small, and it is not easy to bend, but the structure of the head is relatively complex, and the blind area of the pipe test exists.
端面密封取决于密封材料之间的压力和管口的端面实现管口密封的目的,其好处是测试头结构简单,通用性好,但密封材料功能、油水比和压力伺服控制系统要求更高。
The end face seal depends on the pressure between the sealing materials and the end face of the pipe mouth to achieve the purpose of the pipe mouth seal. The advantage of the end face seal is that the structure of the test head is simple and the versatility is good, but the function of the sealing materials, the oil-water ratio and the pressure servo control system require higher requirements.
