About STRAUB

STRAUB Werke AG, based in Wangs (Switzerland), manufactures pipe couplings and pipe connection solutions that are used worldwide across a wide range of industries. The product range comprises tension-resistant pipe couplings (including STRAUB-METAL-GRIP, STRAUB-GRIP, STRAUB-PLAST-GRIP, STRAUB-COMBI-GRIP), non-tension-resistant pipe couplings (STRAUB-FLEX, OPEN-FLEX, STEP-FLEX, SQUARE-FLEX, REP-FLEX, STRAUB-CLAMP) as well as fittings such as bends, tees, reducers and flange adapters. In addition to product manufacturing, the company offers complete solutions: from situation analysis through pre-engineering, engineering and system procurement with quality assurance to installation, commissioning, service and maintenance. Reference projects include, among others, the winter recirculation line of the Gösgen nuclear power plant, a pressure pipeline for the Vorarlberger Illwerke at the Klösterle power station, a wastewater treatment system in Singapore and drinking water supply projects in Florida. The couplings are made, among other things, from steel (electro-galvanized with epoxy coatings) and with stainless steel band inserts.

Materials & Processes

Stahl

Steel

Band inserts and galvanized coupling housings, triple-coated (electro-galvanized, double epoxy coating) for corrosion protection.

Edelstahl

Stainless steel

Band inserts for pipe couplings, e.g. for angularly offset pipe connections at the Gösgen nuclear power plant.

GF-UP

GRP-UP (glass-fibre reinforced plastic)

HOBAS pipes used in the application context, made from unsaturated polyester resins, glass fibres and mineral reinforcing materials.

Guss

Cast iron

Cast iron pipe lines joined in the application context (e.g. PAM cast iron pipeline with push-on sockets).
