Product Description
1)The equipment is used for kinds of steel pipe pressure-bearing and
testing non-standard equipment.
It adopts two lifted rollers to hold the tested steel pipe, using
the thrust of master cylinder to press the pipe between the thrust
plate and the pressure plate, so that the pipe two ends can be
sealed(end face seal or radial seal). Based on high-
volume low-pressure pump to complete the water injection, and then
use high-pressure pump to complete high pressure test.
2) The equipment uses master oil cylinder thrust and smart balance
control system(oil-water balance) to do hydrostatic testing. It
adopts PLC programming smart control touch screen operating system,
displaying the test pressure at real-time. The
testing pressure curve can be automatically printed and also can be
stored in computer hard disk.
3) The equipment is with simple structure, high production
efficiency, wide range of product specifications, movable and
lockable steel pipe pressure head push plate which can test various
lengths steel pipes. The equipment applies to hydrostatic
testing for seamless steel pipe, welded steel pipe and spiral
welded pipe.
Hydraulic System
The hydraulic oil in the tank through the motor drives the
high-pressure pump into the oil flows through a check,
high-pressure oil filters, differential pressure valve set, servo
valves, into the oil cylinder. Computer control signals to the
servo valve, the control, and direction of the servo valve opening
to control the flow into the cylinder to achieve constant test
force, constant displacement control. through the tubing, pressure
tubing through, and the oil return valve to the tank.

Pipe installation – Sealing – water filling – pressurization –
pressure relief – drainage – pipe uninstallation 
FAQ
Q: Are you a manufacturer?
A: Yes, we are a manufacturer. We have 4 factories ( Machining,
Assembling, Heat treatment, and Moulding ). We also have our own
R&D department. Welcome to visit us.
Q: What kind of payment term do you do?
A: We do T/T and L/C.
Q: What info do you need before giving me the price and proposal?
A: Since we design individual machines based on our customer's
requirements, we need your desired products' basic dimensions,
including all the pipe diameter(or tube length), thickness range,
usage, raw material steel grade, coil weight, and degree of
automation.
Q: What should I do if I just start a new business?
A: Contact us immediately, we provide a free consultant for
pre-sales service. Also, we can help you solve the raw material
(steel coil) purchase, worker training, international market price,
and more.
Q: How do you do QA?
A: We have a special team to do strict QA, this is one of our
strengths:
(1)Every gearbox will be tested for 8 hours with oil inside to
guarantee there is no leak.
(2)Every shaft will be inspected for centering jumpiness.
(3)Every roller will be checked to make sure it's in the range of
tolerance critical parts will be inspected for all dimensions.
Q: Why I should choose you? what are the differences between you
and other Chinese suppliers?
A: We are concentrating on pipe-making machines for more than 20
years. We have constructed many steady trading partners in Asia,
Africa, the Middle East, Europe, and South America throughout the
years.
ur, innovatively designed production line and every single unit of
the production line are economical and practical.
