Hydro Testing Machine for Straight Seam Welded Steel Tube

Product Description

technical features:
1. High accuracy rate of pressing: high-resolution pressure sensor is used to monitor the pressing process, and real-time display and record the pressing value, pressing curve, and leak pipe indication. When there is a pipe leak, the alarm can be realized, and semi-automatic re-inspection can be realized, so as to avoid mistakenly thinking that the steel pipe is defective due to equipment reasons.
2. Multiple observation methods: Equipped with shockproof pressure gauge. Manual observation, pressure gauge indication, large screen display pressure curve, large screen display pressure value, touch screen pressure value and leak pipe alarm, etc.
3. Simple re-inspection: Once a leak occurs, manual intervention can realize semi-automatic re-inspection, and repeated re-inspection can be repeated many times.
4. Simple operation and easy maintenance: the test pressure head is easy to install and disassemble, and the sealing ring is easy to replace.
5. Low cost of use: The main parts of the wading system are made of stainless steel, and the stainless steel parts below 89 have test pressure head bushings, valve flanges, and sealing flanges. The 219 test pressure head is galvanized to prevent rust.

Product Parameters
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.

Flow chart and product unit
Loading → Pipe-Connecting → Pipe-Filling → Water-Pressuring Pressure → Maintaining → Pressure Releasing → Draining → Exit Pipe A hydraulic tester is used to perform leaking and hydraulic pressure test on ERW or spiral welded pipes.
The test involves sealing the two ends of the pipe, and filling the pipe with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test pressure.
Pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss. Huaye hydraulic tester reaches API standard.

FAQ
Q: Are you manufacturer?
A: Yes. We are manufacturer. We have our own technical team. Welcome to visit us.

Q: What payment terms do you accept?
A: We are flexible on payment terms, please contact us for details!

Q: What info you need before you make the proposal?
A: The pipe diameter and thickness range which you need or the profile drawings material information, your special requirements and speed of the machine.

Q: How do you do QA?
A: We have special team do strict QA, this is our strengths:
(1)Every gear box will be tested for 8 hours with oil inside to guarantee there is no leak.
(2)Every shaft will be inspected for the centering jumpiness.
(3)Every roller will be checked to make sure it is in the range of tolerance critical parts will be inspected for all dimensions.

Q: Why choose you? What is the difference between you and other Chinese supplier?
A: You can get higher quality product & better professional service from TENGDI with same price.
