Introduction

Pipe Hydrostatic Pressure Testing Machine Used to determine thermoplastic pipes (such as PE pipes, PP-R, PP-B, PE-X, PERT, PVC, PVC-U, PVC-M, steel mesh frame reinforced pipes, and aluminum-plastic composite pipes and other pipes) Resistance to internal pressure destruction test under constant internal pressure and constant temperature for a long time. The equipment is a fully automatic unattended working mode, and the operator can leave after loading the sample. The experiment is automatically terminated when the experiment time is reached. The experiment curve and data are automatically recorded. If the sample is damaged in the middle, the experiment will be automatically terminated.

This testing machine adopts advanced control algorithm, loading pressure smooth, hold pressure stable, swelling rate high, which can ensure 100% success of test.

Characteristics

This testing machine is composed of host machine (pressure control system), constant temperature water tank and professional end enclosure (end cap) three parts. Among them, the constant temperature water tank and professional end enclosure can be connected with different host machine, it can work together to complete the test.

End enclosure (caps)304 Stainless steel

End caps are designed for internal hydrostatic pressure testing of pipes and fittings. It is used to seal the sample in order to generate internal pressure in the sample, with the characters:

• Casting A-type structural fixture, without intermediate tie rods, has super high pressure resistance.
• The structure realizes the assembly method of clamping first and then sealing, and the success rate ofclamping and sealing at one time reaches 100%.
• Radial seal, suitable for a wide range of pipes (applicable to PE, PVC, PP-R, steel-lined composite pipes, etc.
• Split type clamping structure, easy to install, can realize automatic centering.
• Large-diameter clamps are suitable for a wide range of pipe diameters. The sample does not need to be reshaped before the test, and it can be easily inserted into the head
• The clamp is light in weight, and the individual components are equipped with hoisting devices, which are convenient to carry, convenient and quick to test and assemble, without special clamping devices, high work efficiency and low long-term use costs. The assembly time of the test fixture for large pipe diameters above Φ200 needs to be less than 30 minutes, and the assembly time for tools of Φ200 and below needs less than 10 minutes
• The casting fixture is made of high-quality 304 stainless steel material, which is pickled and passivated after casting, which has super anti-corrosion ability and long service life
• The unique lifting chain device avoids the problems that the thin-walled tube sample is broken and the bottom clamp is difficult to lift; the hooks for the clamps are provided for easy suspension
• There is a permanent mark on the fixture to indicate the model information.
• The model of the radial outer sealing fixture
