Frequently Asked Questions about Fittings
Which standards do your carbon steel fittings comply with?
Our EN 10253 fittings comply with European standards EN 10253-1 (general requirements) and EN 10253-2 (non-alloy and carbon steel). For the American market, we supply ANSI B16.9 fittings for welded fittings, ANSI B16.11 fittings for forged fittings, and corresponding ASME B16.9 fittings and ASME B16.11 fittings. All our products are certified fittings 3.1 according to EN 10204.
What is the difference between butt weld and socket weld fittings?
Butt weld fittings comply with EN 10253 and are welded end-to-end with the pipe, ideal for large diameters and industrial plants. Socket weld fittings according to ANSI B16.11 are inserted into the pipe and are perfect for small diameters in mechanical plants and petrochemical plants.
For which types of systems are your fittings suitable?
Our fittings are ideal for gas distribution systems, water distribution systems, mechanical plants, infrastructure plants, thermal plants, heating systems and petrochemical plants. We provide complete solutions for water systems fittings and gas line fittings.
Which sectors and companies do you supply fittings to?
We supply certified fittings to construction companies, industrial companies, professional installers, hydraulic materials dealers, technical distributors, water network maintainers and municipal gas network maintainers. We also serve metalworking companies, plant maintenance companies, plant engineering firms and metal fabrication shops.
What certifications are provided with the fittings?
Every supply of steel fittings includes certificate 3.1 according to EN 10204 at no additional cost.
