Pipeline Reliability

We validate the leak-tightness, safety, and reliability of your pipeline.

Pressure Testing & Commissioning

When you need to commission a new gas or water pipeline or a new connection, ensure it is safe and reliable in operation, Radius Subterra have the competencies and equipment to conduct integrity testing operations before the pipeline is put into service.

Commissioning

As part of the commissioning operation, we have the ability and skillset to perform chlorination operations of your water pipeline, in line with industry or the water utility’s specification, using our own mobile equipment and specialist teams.

Hydrostatic Pressure Test

The hydrostatic pressure test is the most common method employed for testing water pipes and is also used as a proving test for gas systems designed to operate above 2 bar, before a pneumatic test is applied.

WRc type 1 and type 2 tests carried out
Proves the integrity of a gas or water main
Carried out in accordance with WRc, BS EN 805 and the UK Gas Industry Standard
Disposal of water in accordance with Environmental Regulations
Full data logging and test certification

Pneumatic Pressure Test

The pneumatic pressure test is a leakage test that demonstrates the leak-tightness of a polyethylene or metallic gas main.

All our operations are carried out by our GNO2 or Gas Safe certified technicians who test and commission downstream pipework.

Drying operations carried out in accordance with IGE/TD2/Ed4
Full data logging and test certification
Hydrostatic proving test can also be carried out prior to pneumatic test for intermediate pressure gas mains

Advanced Acoustic Pressure Test (AAPT)

The AAPT is a sophisticated, specially engineered method of testing polyethylene and steel pipelines for gas distribution.

It is quick to perform with exceptional accuracy, by use of acoustic technology, software and hardware packages that measure the air temperature variations within the pipeline to detect and measure leakage.

Through a set of calculations performed automatically, the AAPT testing system can swiftly validate the integrity of a gas main.

Creep allowance applied for polyethylene mains
Test package not limited by SDR ratings or operating pressure
Significant time savings on standard pressure tests
Reduced pipeline commissioning time
Full data logging and test certification

Chlorination of water pipelines

Chlorination of new pipeline installation and extensions is essential, before its connection to the water supply network, to help safeguard drinking water quality.

At Radius Subterra, our proficient teams are fully equipped with mobile units to carry out chlorination and de-chlorination of all water pipelines to your specification or industry guidelines, before the main is commissioned.

Using specialist equipment, our own water tanks and calibrated trailers, the chlorination process is performed by the addition of sodium hypochlorite through the dosing trailer. Once the chlorination process is complete, we de-chlorinate the water using sodium bisulphite before it is safely discharged in accordance with Environmental Regulations.

Test carried out by competent Water Hygiene and City & Guilds certified technicians
Water supply integrity is maintained
Specialist dosing trailer for chlorination and de-chlorination of main
Water sampling and laboratory testing available
Full data logging and chlorination certification
Safe disposal of de-chlorinated water
