With design offices across the world, utilising the most up-to-date engineering and design software, we offer a fully coordinated service: stress analysis of pipework, hanger selection, design and detailing, 3D CAD modelling, manufacturing and contract management. This service ensures cost-effective hanger systems, delivered in accordance with design requirements.
Manufacturing Standards
Our objective is to manufacture & supply the same products at all of our manufacturing facilities regardless of location. Material grades are carefully chosen to give equivalence in terms of mechanical properties, weldability and physical performance. Comparison tables are given in each of the key sections of our catalogue. Our standard product range meets the requirements of ASME B31.1, ASME B31.3, MSS-SP58 & BS EN13480: Part 3 where these specifications are applicable. Our cryogenic pipe supports are generally designed to meet the specific needs of the client and our molded polyurethane foam is manufactured in compliance with the CINI manual ’Insulation for Industries’.

We also design and manufacture pipe clamps and ancillaries in other materials to suit particular applications. Examples of this are:
- Hanger rods and ancillaries in alloy steel for boiler integral pipework
- Low-temperature carbon steel grades
- Austenitic stainless steel for corrosion resistance, cryogenic or high temperature service
- Nickel alloys
Finish
The standard finish for pipe clamps and ancillary items is self-colour. Other available finishes are:
- Hot-dip galvanised
- Zinc-plated
- Zinc-phosphate primer
- Zinc-silicate primer
- Corrosion-resistant paint finishes to customer specifications
Thread Form
All threaded components (excluding the USA) are supplied ISO metric coarse unless otherwise stated. Other thread forms can be supplied at extra cost. The USA uses UNC threads up to 4″ diameter and UN thread above 4″.
