Product Details
Hydraulic press for longitudinal seam welded pipes
Product Introduction
A hydrostatic testing machine for longitudinal seam welded pipes is equipment used to test such pipes. The test involves sealing both ends of the pipe and filling it with a liquid—typically water, which may be dyed to facilitate visual inspection—and then pressurizing the vessel to a specified test pressure. Pressure tightness can be verified by closing the supply valve and monitoring for any pressure loss. The hydrostatic testing machines designed and manufactured by Huaye meet API standards.
The primary factors determining the model of a hydrostatic testing machine are as follows.
• Pipe diameter range
• Maximum test pressure
• Maximum test pressure for the largest pipe diameter
• Pipe wall thickness
• Pipe end (flat or beveled)
Armed with this information, our highly experienced engineers can determine the appropriate machine type, maximum hydraulic power, seal configuration, and more. Huaye boasts extensive technical expertise and custom‑designs a wide range of hydraulic testing machines to meet each customer’s needs. Whether it’s ultra‑large diameters, ultra‑high pressures, exceptionally long lengths, or extremely high speeds, Huaye delivers tailored solutions at the most competitive prices.

Shipping and Delivery
Although welded pipe equipment is inherently bulky and heavy, it is largely modular, and we strive to design each module so that it can be loaded into a standard shipping container.
However, there are always certain specialized components that, no matter how the design is modified, still exceed the container’s internal dimensions. In such cases, we resort to using frame containers or open-top containers.
If there are too many oversized or overweight components, we will opt for shipment on a bulk carrier.
