This machine is mainly used for pressure testing of small diameter spiral welded pipes. It can adopt two sealing forms: polyurethane end face sealing or radial large gap sealing. It is equipped with an oil water balance system, and the computer collects, records, stores, and prints test results. It has the advantages of stable pressure maintaining and high safety. The hydraulic pipe pressure testing machine adopts mature and reliable advanced processes and technologies currently available internationally, with the main goal of detecting the quality of finished products and eliminating stress. The physical quality of the product, production costs, various consumption indicators, and labor productivity meet the requirements of product technology and efficiency.
Specification of Hydrostatic Pipe Pressure Testing Equipment for Small Diameter Pipe
Composition of Hydrostatic Pipe Testing Machine
The equipment mainly consists of three parts: the water press body, water supply system, and hydraulic station.
Hydraulic press body:
The hydro pressure testing machine body including: main beam, fixed support, mobile support, mobile sealing head, pipe clamping device:
1. Main beam
There are a total of three main beams, one end of which is connected to a fixed support by a column pin, and the other end is supported by a moving support to withstand the axial force generated by the water pressure in the pipe during the hydraulic test.
2. Fixed support:
Located at the positioning end of the pipe and connected to the main beam through six column pins, it is equipped with a water filling valve, a pressure boosting pipe, and a pressure transmitter. The pipes can be filled with water through the water filling valve, and the pressure is increased through the pressurization pipe. The pressurization process is displayed by the pressure transmitter.
3. Mobile support and mobile sealing head:
The movable support is connected to the movable sealing head by an oil cylinder. The movable support can be moved on the crossbeam according to the length of the pipe, and fixed with column pins after being moved to a suitable position. The movable sealing head is equipped with an exhaust valve for exhaust during pipe water injection. After the clamping device clamps the pipe, the sealing head is moved by the oil cylinder to clamp and seal both ends of the pipe.
4. Clamping device:
The clamping device integrates pipe alignment and clamping, and is placed at both ends of the pipe on the bottom beam of the hydraulic press. It is fixed by a set screw to adjust the position of the pipe, and then the pipe is clamped.
