Materials & Grades

Creative Piping Solutions is a premier manufacturer and supplier of stainless steel piping components, offering a comprehensive range of products including buttweld fittings, forged fittings, flanges, and pipe spools. Our stainless steel buttweld fittings, available in sizes from 1/2" to 48", are manufactured to meet ASME B16.9 standards. Whether it’s elbows, tees, reducers, or caps, these fittings are designed to ensure seamless flow and reliable connections in high-pressure and corrosive environments, making them ideal for industries like oil & gas, petrochemical, and power generation.

Our forged fittings, available in threaded and socket weld configurations, are precision-engineered to handle compact and robust connections. Produced as per ASME B16.11, these fittings come in pressure classes of 3000#, 6000#, and 9000#, ensuring exceptional strength and leak-proof performance. Made from premium grades like 304, 316, and 321 stainless steel, our forged fittings are widely used in applications requiring high resistance to heat and corrosion.

We also specialize in stainless steel flanges, designed to deliver secure and durable connections in diverse piping systems. Available in sizes up to 48" and adhering to ASME B16.5 and B16.47 standards, our flanges include weld neck, slip-on, blind, and lap joint types. They are manufactured using top-quality stainless steel grades, ensuring outstanding performance in critical systems where strength and reliability are essential.

To complete the range, our stainless steel pipe spools are fabricated to meet specific project requirements. Built with precision and attention to detail, they use grades like 304L, 316L, and duplex stainless steel, ensuring excellent corrosion resistance and structural integrity. Whether for high-pressure pipelines or custom installations, our pipe spools are designed to provide superior performance and efficiency. At Creative Piping Solutions, we are committed to delivering high-quality stainless steel products that exceed client expectations in every application.
