Kaizen Steel Industries is a dynamic company that was established over a decade ago to meet the growing demand for ASME B16.11 Threaded Full Coupling standards in fittings like elbows, tees, crosses, reducers, nipples, and couplings made from materials such as stainless steel, carbon steel, and high nickel alloys.
We manufacture, export, and supply Threaded (THD) Fittings that meet both national and international quality standards.
Kaizen Steel Industries produce all three types of fittings: Buttweld (BW) fittings, Socket Weld (SW) fittings, and Threaded (THD) fittings according to ASME B16.11 and other international standards. We export our high-quality ASME B16.11 Threaded Full Couplings to countries like USA, UK, and South Africa.
Threaded Reducing Couplings are designed to handle repeated cycles of tightening without the threads loosening during drilling. These Threaded Couplings can either be welded or screwed onto the pipe, depending on the needs, and are made according to both national and international quality standards.
Kaizen Steel Industries also supply Full Couplings under ANSI B16.11, which are used in various industries, including chemical processing, oil refineries, petrochemicals, and more. We maintain a large inventory of Forged Steel Threaded Couplings in custom sizes to meet customer requirements.
We specialize in manufacturing Threaded Full Couplings in line with ASME B16.11 / BS 3799 standards. These standards cover pressure-temperature ratings, dimensions, marking, tolerances, and material requirements. Be sure to check the Threaded Reducing Coupling dimensions before purchasing to ensure they meet the required sizes.
