Kaizen Steel is a leading manufacturer of ANSI/ASME B16.9 Reducing Cross fittings, also known as Unequal Cross fittings, based in Mumbai, India. Our range includes Carbon Steel (CS) Reducing Cross Tees and Stainless Steel (SS) Unequal Cross fittings. We adhere to standards like BS1640 and MSS SP-75, ensuring high quality and precision in our fittings.

The ASME B16.9 Reducing Cross is a type of pipe fitting with four branch ends, each of a different diameter, making it ideal for connecting pipes of varying sizes. Commonly known as four-way fittings or cross branch lines, these fittings are essential for complex piping systems.

Our ASME B16.9 Unequal Cross fittings can be configured in two primary ways:

  1. One inlet and three outlets.
  2. Three inlets and one outlet.

These fittings can feature solvent-welded sockets or female-threaded ends, making them versatile for various applications. Our products are designed to meet stringent international standards, ensuring reliability and durability in diverse industrial environments.

We are prominent manufacturers of ASME B16.9 Reducing Cross Fittings and Grooved Reducing Cross Exporters based in India. Our inventory includes ANSI B16.9 Pipe Reducing Cross Fittings, with sizes ranging from 1/2 to 48 inches, available in Carbon Steel Buttweld. Our fittings are renowned for their high quality and durability, catering to a variety of industrial needs.

Cross fittings can exert stress on pipes as temperatures fluctuate, primarily because the Unequal Cross Pipe Fitting connects four points. The dimensions of our Reducing Cross Fittings are as follows: Seamless Cross Fittings can be produced with an outside diameter ranging from 1/2 inch to 24 inches. For ERW, Welded, and Fabricated types, our stock typically includes fittings with dimensions between 1/2 inch and 48 inches. 

We manufacture fittings like the Reducing Cross Tee according to buyer specifications, with wall thickness sizes available in schedules 3mm to 40mm / SCH 5, SCH 10, SCH 20, SCH 30, SCH 40, STD, SCH 80, XS, SCH 60, SCH 80, SCH 120, SCH 140, SCH 160, and XXS.

Our range includes various types of crosses such as Seamless, Welded, Equal Cross, and Grooved Reducing Cross. We produce ANSI B16.9 Pipe Reducing Cross Fittings in metals like Alloy Steel, Duplex, Stainless Steel, Nickel Alloys, Low Temperature Steel, Carbon Steel, and Cupro Nickel, ensuring a wide selection to meet diverse application requirements.
