Alloy Steel Pipe Fittings

Repute Steel & Engineering Companyis a well-known company that makes alloy steel pipe parts that meet ISO 9001:2008 standards. We have been committed to offering new and reliable solutions for many industries since 2004.

Our alloy steel buttweld fittings are mostly made from long-lasting chrome moly metals, which means they work very well and last a long time. We have a lot of different sizes, types, schedules, and pressures to meet the needs of a lot of different uses. We make sure that our parts meet strict industry standards like ANSI B16.28, ANSI B16.9, MSS SP-43, MSS SP-79, and ASME SA234.

Alloy steel fittings from Repute Steel & Engineering Company work well in moderate to high-temperature settings and are perfect for pressure piping and making pressure vessels. To keep their best mechanical qualities, our hot-formed or forged chrome moly fittings go through a strict annealing, normalizing, and tempering process.

We are experts at making alloy steel weld fittings, which are in high demand in many fields, including the oil and gas, chemical processing, marine, petroleum and refining, and navy. We sell many different types of alloy steel fittings, such as pipe caps, equal crosses, tees, stub ends, reducing tees, pipe bends, pipe nipples, and more. Our customers come from all over the world. We have a big presence in China, Italy, South Africa, Sweden, the UK, Canada, Finland, Zimbabwe, Malaysia, the Philippines, France, Germany, and the Netherlands.
