The Oil & Gas industry is divided into three major segments — upstream, midstream, and downstream — plus subsea & offshore operations. Each segment has specific piping requirements based on operating pressure, temperature, and media. Repsol Steel LLP supplies pipe fittings across all segments with material and certification support tailored to each application.
All oil and gas pipe fittings we supply are accompanied by Material Test Certificates (MTC) and dimensional inspection reports, with NACE compliance documentation, hardness test reports, and third-party inspection available on request.

Correct oil and gas pipe fitting selection is critical to ensuring a leak-free piping system and long-term operational safety. The fitting type, material grade, and schedule or class must be matched to the operating pressure, temperature, and media. Our technical team recommends evaluating four key factors before finalizing an oil and gas pipe fitting:
