Energy & Water
Cheshire Seals and Components has operated within the subsea oil and gas supply chain for many years. Included within our portfolio of high integrity products are super duplex hot stab connectors and high-pressure hydraulic test equipment. We also support manufacturers of pressure vessels, pipe integrity checking equipment, and pipe coatings, and we supply high accuracy shafts and flanges for use in progressive cavity pumps.
We also have experience of batch producing complex industrial-scale water treatment equipment on behalf of major contractors for the water sector.
Our seal manufacture experience is of major benefit to customers in this sector, as it is rare for high-pressure seals to be easily obtained “off the shelf”. Careful consideration of fundamental seal geometry, along with the exact grade of material, and with the potential requirement for additional components such as back-up rings is necessary. We have years of experience in manufacturing system-critical seals for use in incredibly demanding applications, with static, rotating, and/or reciprocating motion. We will produce your bespoke solution for your application, and can manufacture this in everything from one-offs for trials or unique tools, right through to large-scale manufacture to support the lifetime of your project.
In addition to our range of more conventional metal grades, we regularly source and machine less-common stainless steel variants which are of particular interest to our energy sector customers:
- Austenitic 321, 316LN
- Duplex and Super-Duplex 31803 / 32550 / 32750 / 32760
- Martensitic 410, 416
- Precipitation hardenable 17-4 PH
We can also produce products using NORSOK-approved materials for our oil and gas customers.
