Explosion-Proof Pressure Test Chamber for Oilfield Equipment
High-pressure hydrostatic tests are a necessary part of oilfield and industrial equipment manufacturing. They are also one of the most dangerous operations on the yard. When flanges, valves, hoses or manifolds fail during testing, fragments and high-energy fluids can cause serious injury and damage in a fraction of a second.
To protect people and equipment while still carrying out reliable testing, many operators are moving their pressure tests into a dedicated explosion-proof pressure test chamber. GPE’s containerized Explosion-proof Pressure Testbay Box (PTB) is designed exactly for this job.
This article introduces the PTB test chamber, its key parameters, and the advantages it brings to oilfield and industrial test operations.
Product Description: Explosion-Proof Pressure Testbay Box (PTB)
The GPE Explosion-proof Pressure Testbay Box is a customized, sectional, long test chamber used for high-pressure testing of a wide range of workpieces. It is designed as a containerized unit that can be installed on a skid or vehicle and deployed directly at the test site.
The PTB can work with different test media, including clean water and glycol or hydraulic oil, and is suitable for use in:
- Oilfield equipment manufacturing and repair bases
- Chemical construction projects
- Pipeline and plumbing testing
- Coal, smelting, shipbuilding and other heavy industries
The chamber can be engineered to meet your general safety standards as well as specific project requirements, including dimensions, configuration and monitoring functions.

Key Advantages of GPE Explosion-Proof Pressure Testbay Box
The PTB test chamber combines explosion-proof protection with flexible on-site operation. Its main advantages include:
- Full-coverage visual monitoring
The chamber is equipped with fixed and movable PTZ cameras. With six adjustable cameras and night-vision capability, the operator can observe the test workpiece from multiple angles without entering the danger zone. - Modular sectional design
The PTB is made up of multiple sections that can be assembled according to the length and shape of the workpiece. Sections are connected by M30 bolts, which makes it easy to extend or shorten the chamber as needed. - Skid-mounted or vehicle-mounted for easy relocation
The modular and containerized design allows the chamber to be skid-mounted or installed on a truck. This simplifies transport between job sites and supports field testing close to the production line or wellsite. - Safety interlocks and self-locking door switch
A self-locking switch is integrated to prevent the door from being opened while tests are underway. This reduces the risk of accidents caused by people or foreign objects near the door during high-pressure testing. - Flexible configuration to match different test workpieces
Thanks to its sectional structure, the chamber can be assembled in different combinations. It can accommodate valves, flanges, manifolds, hoses and other components with different lengths and shapes. - High-strength protective wall
The 70 mm protective wall is made of steel plate, bulletproof fiber and intermediate interlayers. This multi-layer structure provides strong energy-absorbing capacity to contain fragments and shock waves in the event of a test failure.
Typical Applications
The Explosion-proof Pressure Testbay Box is suitable for a wide range of high-pressure test scenarios, including but not limited to:
- Pressure testing of API 6A and API 16C wellhead and manifold equipment
- Hydrostatic testing of valves, flanges, hoses and fittings
- Proof testing of assembled skids and pipe spools
- Laboratory and R&D pressure test programs requiring enhanced safety
By moving these tests inside an explosion-proof chamber, operators significantly reduce risk to personnel while still collecting the data needed for quality control and certification.
