Today I will be answering some of our frequently asked questions about Swivel Joints.
What Size are your Swivel Joints?
Our smallest size is ½” but we have machining capabilities to offer up to a 72” bore. Of course, any size in between this is also available. Our standard designs range from ½” to 12”. Over 12” our large bore engineered designs are supplied.
What Materials do you offer?
As standard we manufacture Swivel Joints in 3 metals – Aluminium, Carbon and Stainless Steel. We do tend to use different grades such as 304L and 316L, subject to requirements. However, we always try to provide a product suited to the needs of our customers, and will supply exotic material such as Hastelloy, Duplex, Titanium and even PTFE lining on request.
What end connections can we offer?
We supply what you require. Don’t get me wrong our usual’s include Weld End (BW SCH40), Flanged (ANSI, PN, DIN) and Threads (BSP,NPT). However, we are more than happy to accommodate your needs, and have supplied Hammer Lug Unions, Tri Clamps, and RJT fittings over the years.
Can you do Cryogenics? Can you do High Temperatures?
The answer to both is yes. For cryogenics we supply a Swivel with a nitrogen chamber around the bearings to prevent them for freezing. For high temperatures we provide jacketed Swivel Joints. These can also be heated electrically or with oil on request.
Can you provide Elbows on the Swivel Joint?
We certainly can. Internationally Swivel Joints are supplied in the following standard styles.
Of course, if you require custom designs with varying articulated pipework, we can supply these too.
What pressures can your Swivels go to?
This is an extremely broad question as it differs subject to size. Our high-pressure hydraulic Swivels and Multiport Rotary Unions can reach pressures of up to 15,000 psi. For high pressure requirements on larger bore Swivels we take it case by case. We can increase the number of ball and roller bearings as well as the Swivel wall thickness to accommodate greater pressures. We also perform hyperbaric testing for external pressures when supplying Swivels for a Subsea environment. We work together with you to ensure your satisfaction throughout the process, so get in touch with us today and start to build your long-term relationship with us, so we can help your business grow and operate safely.Tel : +44 (0) 1763 248650Email : sales@ewfm.co.ukYou can keep up to date with our latest news and updates through our social media channels including LinkedIn, Facebook, Twitter & Instagram
