Stainless steel fittings and pipe couplings are used in a wide range of industrial sectors—anywhere where stainless steel is in demand due to its high corrosion resistance, purity, and long service life. Stainless steel is an extremely durable material that is nearly 100% recyclable. Thanks to its corrosion resistance, it ensures a long service life and infrequent replacement cycles. For this reason, stainless steel fittings are used in many different industrial sectors. Generally speaking, the primary users are the hydraulics and fluid technology, process engineering, and measurement and control technology sectors. Other sectors include, for example, the food industry, hydrogen applications, the semiconductor industry, marine engineering, and the automotive industry.

Stainless steel fittings and screw connections are primarily intended for gaseous and fluid applications. Depending on the pressure range, temperature, medium, and specific application, the appropriate stainless steel components are selected to ensure maximum safety, efficiency, and durability.

Yes, Schwer Fittings stainless steel clamping wedge ring fittings (also known as clamping ring fittings or two-ring fittings) are suitable for hydrogen applications. They are characterized by extreme gas tightness, are vibration-resistant, and the use of high-quality stainless steel (AISI 316 / AISI 316 L) guarantees material safety. The clamping wedge ring fittings are EC79 and DNV certified. Schwer Fittings supplies leading companies in the hydrogen industry and has extensive experience in selecting the right components, both technically and economically. User videos demonstrate the process and applications for hydrogen customers. 

Stainless steel has a longer service life and requires minimal maintenance costs. This reduces the need for frequent replacement and, consequently, consumption. Stainless steel also offers high corrosion resistance. As a result, no additional environmentally harmful coatings are necessary. In the long run, therefore, stainless steel fittings and screw connections are not necessarily more expensive than steel connections or alloys.

In addition to standard stainless steel grades such as 1.4571 (AISI 316 Ti), 1.4408 (AISI 316), 1.4404 (AISI 316L), and 1.4435 (AISI 316L), special materials for specific applications are also used. Schwer Fittings offers a variety of materials for certain products. This is particularly true for threaded fittings, where users can choose from different grades depending on the application and industry.

Schwer Fittings has already produced successful user films and reference videos with numerous well-known customers, including BASF SE, WILO SE, Enapter AG and IGT GmbH. In these videos, the products, technical service and project procedures are explained in detail. The focus is always on trust, partnership and close cooperation with our customers.
