District Heating NDT Inspection

At WHE NDT we specialise in thin wall pipe inspections commonly found in underground and over ground District Heating networks. Our team have developed advanced Phased array and traditional ultrasonic inspection methods and techniques, that allow for a very conclusive and efficient weld inspection. We work with our customers to provide a JIT service that allows them to excavate, pipe fit, weld, NDT, sleeve, backfill and reinstate, efficiently.

Our DH projects take us all over the UK and Ireland but the majority take place local to us in London.

Weld Procedures & Welder Qualifications

Weld Procedure Specification

Weld Procedure Specification is the formally written document which provides the welding party with the necessary information for the scope of work they have. This preliminary document is normally provided by the manufacturer, along with test pieces from each welder.

Weld Procedure Approval

Weld Procedure Approval is the next step in the process, whereby the preliminary procedure is reviewed and approved by the inspection body. The approved procedure will come as part of the Weld Procedure Approval Record.
WHE NDT are willing and able to provide this service at your request.

Welder Qualification

Welder Qualification is the final step, using test pieces provided by each welder. The welded components are inspected and tested by various NDT methods, alongside destructive mechanical tests.
We travel to our clients, working around your schedules, offering an efficient and great value service.

Tank & Plant Room Inspection Techniques

Ultrasonic thickness surveys are utilised to see if the pipe wall thickness is starting to corrode and or diminish.

Visual inspections are carried out with every in-service inspection. We comment on general condition of the pipe work and highlight any areas for concern.

Ultrasonic butt weld inspections are carried out to ensure the installation was carried out properly, ensuring the weldment is conforming.

Phased Array Ultrasonic Inspections are used to inspect butt welds. This inspection has a high accuracy and is quicker than conventional ultrasonic inspections. Data is collected during the inspection and is presented to the client upon request.

Magnetic Particle Inspection is a surface inspection method that is used on ferritic material with no paint present or removed. This inspection is very good at finding surface breaking defects and pin holes.

Magnetic Particle Inspection

Magnetic Particle Inspection is used to find surface breaking flaws in ferrous (magnetic) materials. Our experienced and qualified engineers can carry out Magnetic Particle Inspection on various components such as: Forgings, Castings, Machined parts and Weldments. This form of Inspection is ideal for both newly fabricated and in-service components.

MPI or MT is often used to certify welds to CE Marking standards and can be carried out on site by our competent technicians.

Inspection Standard - BS EN ISO 9934-1:2016
