01 Technical summary Certified Marine Cylinders

How class approval works

A certified cylinder starts on paper. We submit the design documents to the classification society and manufacture to the approved drawings. The cylinder is tested in the presence of the class surveyor and delivered with its certificate.

On the welding side we hold welding procedures (WPS / WPQR) approved to Bureau Veritas rules (NR216); our 316L stainless welds are made to these procedures.

Materials chosen for salt water

On the SHS316 both tube and rod are 316L stainless, for cylinders working exposed on deck. On the SHS355 the tube is E355+SR carbon steel and the rod is still 316L stainless; a metallised coating can be applied to the tube on request, and the range goes up to Ø320 mm.

In both series the rod is hard-chrome plated and ground. All cylinders are pressure and function tested before leaving the factory.

06 From the workshop and the field

07 Frequently asked

Questions,
answers.

Which classification societies approve your marine cylinders?

The certified cylinders we have delivered carry DNV and Bureau Veritas approval on a project basis. Lloyd’s Register and RINA are also within the certificate scope in our catalogue; the approval process is run with whichever society classes the vessel.

What is the difference between SHS316 and SHS355?

SHS316 is fully stainless (316L tube and rod), covers Ø32–160 mm and works up to 180 bar. SHS355 has a carbon steel tube (E355+SR) with a 316L rod, covers Ø32–320 mm and works up to 250 bar.

Do you build marine cylinders in non-standard sizes?

Yes. The catalogue dimensions are the standard types; stroke, mounting dimensions and working pressure can be designed to the project.

Where can I download the marine cylinder catalogue?

From the link on this page or the QR code in our printed catalogue. The PDF contains the dimension tables, mounting types and reference list.
