Refinery and petrochemical
Refineries and petrochemical plants mostly work to ASME standards. Weld neck flanges, RTJ (ring joint) connections, spectacle blinds and forged fittings are the core products.
Spectacle blinds, spades and spacers are used for line isolation and maintenance. On high-pressure lines, RTJ faces with ring gaskets are preferred over RF.
Projects usually require material certificates, dimensional reports and traceability. Our products ship with EN 10204 3.1 certificates on request.
