Threaded steel pipes are precision-machined pipes with threaded ends, allowing for quick and easy installation. They provide dependable performance in water, gas, fire protection, HVAC, and industrial piping systems. Available in carbon steel or stainless steel, they come in various sizes, coatings, and custom thread options.

We produce forged fittings and cast stainless steel pipe fittings to meet different needs. Cast fittings are designed to resist corrosion and are suitable for low to medium-pressure systems. Forged fittings are stronger and designed for high-pressure, high-temperature applications such as oil, gas, and chemical pipelines.
