At DSJ Pipework, we are dedicated to delivering superior pipework pressure testing services to industrial and commercial clients across the UK. Our seasoned contractors handle projects of any scale, from small bore systems to extensive installations.

Expertise in Diverse Materials

Our team is proficient in handling various materials, including mild steel, copper, stainless steel, and more. We understand the unique properties and applications of each material, ensuring we recommend the most suitable options for your pressure testing requirements. 

This expertise allows us to provide accurate and reliable results, critical for the integrity of your systems.

Detailed Assessment and Customised Testing Plans

Our process begins with a comprehensive assessment of your pipework system. We evaluate the type of system, the operational environment, and specific regulatory requirements. Based on this assessment, we design a customised pipework pressure testing plan tailored to meet your unique needs.

This ensures that every aspect of your system is tested thoroughly, identifying any potential weaknesses or issues before they become significant problems.

Advanced Testing Techniques

We employ the latest tools and techniques in the industry to perform our pressure tests. Our advanced methods ensure precise and accurate measurements, providing you with reliable data on the condition of your pipework.

Whether it’s hydrostatic testing, pneumatic testing, or any other specialised method, our team is equipped to handle it with the utmost professionalism.

Frequently Asked

The pressure at which pipework should be tested typically depends on the system and the regulations it must adhere to. Generally, the test pressure is 1.5 times the design pressure or operating pressure of the system being tested.

To pressure test a piping system:

  1. Isolate the section to be tested.
  2. Fill the system with water (hydrostatic) or air (pneumatic).
  3. Apply the test pressure gradually using a pump.
  4. Monitor the pressure and check for leaks.
  5. Maintain the test pressure for a specified duration.
  6. Inspect and document the results.

The British Standard for pressure testing is BS EN 805:2000 for water supply systems. It details the requirements for commissioning, including pressure testing.

Copper pipework in the UK is typically tested at a pressure of 1.5 times the working pressure. For domestic systems, this is often around 10 bar (150 psi).

Qualified personnel for pressure testing pipes include certified plumbing and pipework professionals, mechanical engineers, and technicians with specialised training in pressure testing procedures.

Pressure testing is conducted to verify the integrity and strength of pipework systems, ensuring they can withstand operating pressures without leaks or failures. It ensures system safety and compliance with regulatory standards.

  • Hydrostatic Testing: Involves filling the system with water and applying pressure. It’s safer because water is incompressible, reducing the risk of explosive failure.
  • Pneumatic Testing: Uses air or another gas to apply pressure. It is faster and cleaner but poses a higher risk of explosive failure due to gas compressibility.

The duration for pressure testing pipework varies by regulation and system type but generally ranges from 30 minutes to several hours. It should be long enough to ensure that the system maintains pressure and reveals any potential leaks.
