Hydrostatic Testing

Hydrostatic Testing

Hydrostatic Testing - Valve ModificationUnited Valve has the most extensive range of hydrostatic testing equipment of any valve service company in the industry. With 10 dedicated testing machines and a full-time team of hydrotest technicians, we can test virtually any valve, of any size and pressure class.

We can also perform service simulation tests to confirm valve operability over hundreds or even thousands of cycles.

Common testing standards we use for pressure testing include:

  • API 598
  • API 6D
  • ANSI B16.34
  • MSS SP-61
  • MSS SP-67
  • MSS SP-68
  • MSS SP-70
  • MSS SP-80
  • MSS SP-81
  • ISO 5208

Whether it is a 24” class 2500 BWE gate valve or a ½” bronze check valve, we can test it properly and efficiently.

Specialty Machines for Hydrostatic Testing of Large Valves

Most of our testing machines are custom-built in-house; however, we do have a few commercially produced units as well. A very large Porgetti horizontal testing machine is used for the largest API 6D valves, as well as larger, very high-pressure API 600 and ANSI B16.34 valves up to class 4500.

The Porgetti machine is housed in a wood-timber lined steel bunker to allow for safe high-pressure gas or liquid testing. Testing in the bunker is monitored by multiple video cameras.

Two large vertical test machines are utilized for most large valves through size ANSI 48. One machine has a clamping pressure of 840 tons, while the other has an output of 720 tons of pressure balancing force.

Our facility has a large inventory of test blinds in sizes up to ANSI 60. We also hold a huge inventory of BWE test plates in sizes up to ANSI 48, allowing us to quickly and accurately test any BWE valve.

With large testing machines and high-capacity cranes, virtually any valve can be tested in our facility. In addition to our vertical and horizontal valve testing machines, we utilize multiple sets of ball valve end-clamps that are used to keep from damaging interior seals or yielding false test results through over-compression.

Hydrostatic testing is crucial to ensure industrial valve safety and integrity. In addition to hydrostatic testing to API, MSS, ANSI and ISO standards, we can also perform testing with nitrogen, helium, kerosene, methane, or hydrogen. Rely on our team at United Valve for fast, effective industrial valve testing.

Pressure Testing Industrial Valves for Critical Operations

We are well-equipped for pressure testing virtually any size of valve. We have some of the largest testing machines in the country, and employ full time testing technicians who can quickly and correctly test almost any valve type, pressure class, or end configuration.

We can also perform service simulation tests to confirm valve operability over hundreds or even thousands of cycles.

Common testing standards we use for pressure testing include:

  • API 598
  • API 6D
  • ANSI B16.34
  • MSS SP-61
  • MSS SP-67
  • MSS SP-68
  • MSS SP-70
  • MSS SP-80
  • MSS SP-81
