Hydrostatic testing machine (referred to as water pressure machine) is an auxiliary equipment of spiral welded pipe unit, mainly used for pressure testing of produced spiral welded pipes. Our company produces various models of water pressure testing machines, and after years of production experience, through gradual improvement, we have formed the existing design of water pressure testing machine models. This machine is a single pressure test, with a structure divided into three beam and four beam types. The overall structure is reasonable and stable, and has achieved good usage results through production tests. In addition, the end faces at both ends are sealed, using a low-pressure pump for water filling and a high-pressure pump for pressurization. Suitable for hydraulic testing of production of petroleum standard and high-grade pressure steel pipes. The equipment consists of movable supports, fixed supports, stretching beams, pipe pulling devices, high-pressure water systems, low-pressure water systems, hydraulic systems, electrical systems, etc.

The steel pipe to be inspected on the bench - the pressure testing position and the downcomer are raised - the steel pipe rolls into the center of the downcomer - the custody device is raised to the center line of the pressure testing - the moving pressure head moves forward and tightens the steel pipe - the clamping device clamps the steel pipe - fills and exhausts - closes the filling and exhaust valves - pressurizes the booster pump to the set value - maintains pressure Display - Unloading - Moving the pressure head backwards - Pulling the pipe - Lowering the custody device - Rolling the steel pipe into the output rack
1. What other uses does spiral welded pipe have in water supply engineering besides traditional oil pipelines?
Spiral welded pipes have low cost, excellent quality, and fast production speed. At present, preliminary progress has also been made in some special application directions, such as pier piling, tank welding (oil tanks, boilers, etc.), civil air defense engineering, air ducts, drums, steel structure support, pipes for high-rise building pile foundations, bridge type filter pipes, large diameter spiral circular variable square pipes, and so on. Spiral welded pipes are gradually being accepted by more and more industries due to their low cost, high level of production automation, and simple equipment structure. They will have great potential for development in the future.
2. What are the difficulties in on-site construction of spiral welded pipe equipment?
The spiral welded pipe unit can be disassembled as a whole or in sections, with a simple structure and convenient installation. Infrastructure construction can be tailored to local conditions according to on-site facilities. In the future, the spiral welded pipe unit will enter a construction site production mode, greatly reducing engineering costs.
3. What is the diameter range of spiral welded pipe equipment that can accommodate?
welded pipe equipment can be produced separately from φ 325mm to φ 3620mm, with one machine in hand, worry free production
