At IMPAS, we mainly work with grade-316 stainless steel. Our team of specialists works with stainless steel every day, and is familiar with all of its technical characteristics.
Stainless steel is an alloy consisting of iron (Fe), chromium (Cr), nickel (Ni) and several other elements. Stainless steel is defined as an iron alloy containing at least 12% chromium. Stainless steel 316 is easy to work, and is resistant to corrosion. It also performs well at very low temperatures. We make a great deal of cryogenic piping out of stainless steel 316.
The welders that use stainless steel are duly certified. IMPAS is one of just a few companies with the required WPQR (Welding Procedure Qualification Record) and WPS (Welding Procedure Specification) for stainless steel. In addition, our welders are duly certified under NEN EN ISO 9606 and ASME IX and work according to the regulations. These are the European regulations, as set out in EN ISO 15614-6, and the US regulations. The latter are available in ASME-IX. This means that our welders are certified to weld pipes with a variety of diameters and wall thicknesses.
In our workshops, we use tubes and fittings to make complete pipe sections. We use a variation on bend dies to bend the pipe sections. Our range of bend solutions is extensive.
Piping produced from stainless steel enjoys numerous applications. The piping we produce at IMPAS is used in applications such as deck lines. These can include a cargo deck line system for tankers. Our piping is suitable for cryogenic applications as well, with the gas passing through the pipe in liquid or gaseous form. We also produce a large number of stainless steel solutions that are used in engine exhaust systems.
In addition, we often receive orders for other shipbuilding applications, such as loading systems for chemical, oil and LNG tankers. We use stainless steel for equipment builders as well, for purposes such as gas detection.
Our stainless material can be delivered in accordance with the 3.2 material certificate, if desired or required. This offers you certainty as to the quality of the material and ensures that the final product complies with the requirements in the class rules.
Our extensive knowledge and experience offer all of our clients peace of mind. We always have an up-to-date knowledge of the proper standards, and are aware of the requirements of the notified bodies with regard to the technical aspects of ships and offshore structures. We are familiar with the following notified bodies: American Bureau of Shipping, Bureau Veritas, Lloyd’s Register and DNV GL. This makes us a reliable specialist partner for all your piping needs.
