Petrochemical plants are among the most demanding environments for pipe fittings — combining high temperatures, corrosive media, and stringent safety requirements. The full range of buttweld fitting grades is used across ethylene crackers, aromatics plants, polymer production, and specialty chemical facilities.
Pyrolysis furnace transfer lines, quench systems, and fractionation piping. SS 347H for high-temperature furnace outlets. Inconel 625 for the most severe thermal shock and corrosion environments.
Reforming, isomerization, and extraction units. Chrome-moly grades for high-temperature reformers. Hastelloy C276 for acid service in extraction and separation.
Polyethylene, polypropylene, and PVC production piping. SS 316L for process piping. Hastelloy C276 for VCM (vinyl chloride monomer) and chlorinated solvent service.
Acid chlorides, chlorinated solvents, and aggressive chemical intermediates demand the highest corrosion resistance. Hastelloy C276 and Inconel 625 are the workhorses of aggressive chemical service.
