管材静液压试验机夹具是热塑性塑料管材（PP-R、PP-H、PP-B、PE、PVC-U、PE-RT、PE-XT)等管道系统静液压试验时管材端面密封装置，具有安装方便，结构简单、密封可靠等优点。

　　XGY-A型夹具，是管材静液压试验(耐压爆破试验)专用夹具（密封接头），其操作简单，密封可靠，装夹方便，是静液压试验(耐压爆破试验)的夹具（密封接头）。适用于热塑性塑料管材管件管道系统（给水、排水用硬聚氯乙烯PVC-U管材管件 、聚乙烯PE管材、聚丙烯PP、PB管材、管件、压力管道系统、冷热水用无规共聚聚丙烯PP-R等）试验试样端面密封，规格适用于管材直径16-630mm的塑料管材。特殊规格的管材夹具可定做。

　　管材静液压试验机夹具夹具材质分为碳钢和不锈钢两种。完全符合GB/T ≪液体输送用热塑性塑料管材耐内压试验方法≫中6.1中密封接头的规定。

　　1.碳钢夹具结构为:

　　平底型、易装卡，

　　不易泄漏，操作方便。

　　φ110以上夹具为半圆锅状，采用整体精密铸件，无砂眼、无焊接、易装夹，安装成功率可达到

　　2.304不锈钢夹具:为半圆锅状，采用整体精密铸件，无砂眼、无焊接、易装夹，安装成功率可达到

　　3.螺栓、O型圈全部装配齐全。

　　4、管材静液压试验机夹具从种类上分为A型、B型两种密封夹具。

　　A 型 :与 试样刚性连接的密封接头，但两个密封接头彼此不相连接，因此静液压端部推力可以传递到试样中。

　　B 型 :用 金属材料制造的承口接头，能确保与试样外表面密封，且密封接头通过连接件与另一密封接头相连，因此静液压端都推力不会作用在试样上。这种封头可由一根或多根金属拉杆组成，且试样两端在纵向能自由移动，以免试样由于受热膨胀而引起弯曲变形。

　　密封接头除夹紧试样的齿纹外，任何与试样表面接触的锐边都需修整。密封接头的组成材料不能

　　对试样产生不良影响。

　　一般来说，由于管材的形变应力的不同，采用B型封头的破坏时间比采用A型封头的破坏时间短

　　如无一定的预防措施，当试样在低于试验温度的环境下组装，B型封头易使试样弯曲变形。

　　根据 GB /T 评价管材或管件材料性能的试验中，除非在相关标准中有特殊规定，否则应选用A型封头。

　　仲裁试验采用A型密封接头。

　　管材静液压试验机夹具5、从管子规格上分:￠16-￠2000mm, ￠16、￠20、￠32、￠40、￠50、…￠630  ￠ 1800 ￠2000mm.等多种规格。

The clamp of pipe hydrostatic testing machine is a sealing device for pipe end face in hydrostatic test of thermoplastic pipe system, such as PP-R, PP-H, PP-B, PE, PVC-U, PE-RT, PE-XT, etc. It has the advantages of convenient installation, simple structure and reliable sealing.

XGY-A clamp is a special clamp (sealing joint) for pipe hydrostatic test (pressure explosion test). It has the advantages of simple operation, reliable sealing and convenient clamping. It is the preferred clamp (sealing joint) for hydrostatic test (pressure explosion test). It is suitable for sealing the end face of test samples of thermoplastic pipe fittings and piping systems (rigid PVC-U pipe fittings for water supply and drainage, polyethylene PE pipe fittings, polypropylene PP, PB pipe fittings, pressure piping systems, random copolymer polypropylene PP-R for hot and cold water etc.). The specifications are suitable for plastic pipes of 16-630 mm in diameter. Material. Special specification for pipe clamps can be customized.

The fixture material of tube hydrostatic testing machine is divided into two types: carbon steel and stainless steel. It fully conforms to GB/T Test method for internal pressure resistance of thermoplastic pipes for liquid transportation_6.1 sealing joint.

1. carbon steel clamp structure is:

Flat bottom, easy to install card.

It is not easy to leak and easy to operate.

Over 110 clamp is semi-circular pot-shaped, using integral precision casting, no trachoma, no welding, easy clamping, installation success rate can reach .

2.304 stainless steel clamp: semi-circular pot-shaped, using integral precision casting, no trachoma, no welding, easy clamping, installation success rate can reach .

3. bolts and O rings are fully assembled.

4, pipe hydrostatic test machine fixture from the type of A, B type of two kinds of sealing fixture.

Type A: Sealed joints rigidly connected to the specimen, but the two seals are not connected to each other, so the hydrostatic end thrust can be transmitted to the specimen.

Type B: metallic joint ensures that the outer surface of the specimen is sealed, and the sealing joint is connected with another sealing joint through the connector, so the hydrostatic end thrust will not act on the specimen. The head can be composed of one or more metal rods, and the two ends of the specimen can move freely in the longitudinal direction to avoid bending deformation caused by thermal expansion of the specimen.

In addition to clamping the teeth of the specimen, the sharp edges of the sealing joint must be trimmed. The material of the sealing joint can not be made.

It has adverse effects on samples.

Generally speaking, the failure time of B-type head is shorter than that of A-type head because of the different deformation stress of pipe.

Without certain precautions, when the specimen is assembled at a temperature lower than the test temperature, the B-type head will easily bend the specimen.

According to GB/T to evaluate the performance of pipes or fittings, type A head should be selected unless there are special provisions in the relevant standards.

The A seal joint is used in the arbitration test.

Fixture of pipe hydrostatic testing machine 5, from the pipe specifications are divided into: 16-2000mm, 16, 20, 32, 40, 50, 50, 630, 1800, 2000mm. and so on.
