High Performance Stainless Steel Pipes and Fittings

Guangxin PipeTech specializes in high-quality seamless pipes, butt welded fittings, and forged flanges made from stainless steel, duplex, and nickel alloys. We deliver exceptional strength, corrosion resistance, and precise dimensions, backed by strict quality control and fast, customized service for demanding industries like oil & gas and petrochemical.

Seamless Pipe

The cold rolling process is a critical step in the production of stainless steel and nickel alloy seamless pipes. Through multiple cold rolling processes, we can manufacture high-precision, thin-walled seamless pipes. Combined with subsequent processes such as forming, annealing, and straightening, we ensure that the products meet customer requirements for dimensions, tolerances, and physical properties.

Butt Welded Fittings

Guangxin PipeTech's butt welded fittings are manufactured from high-quality seamless or welded pipes. Through multiple stamping and annealing processes, we precisely form products to meet customer-specified shapes and dimensions, ensuring strict compliance with tolerance and pressure resistance requirements.

Flange

Guangxin PipeTech utilizes precision forging combined with advanced machining processes to ensure our flanges deliver outstanding strength, dimensional accuracy, and sealing performance.

Grades

Stainless Steel, Duplex, and Alloy Grades for Extreme Performance

Guangxin PipeTech selects high-quality materials, including stainless steel, duplex stainless steel, and nickel alloys. Stainless steel offers excellent corrosion resistance and good machinability for general environments; duplex stainless steel combines the benefits of austenitic and ferritic structures, providing higher strength and superior resistance to chloride stress corrosion; nickel alloys deliver outstanding performance in high-temperature, high-pressure, and extremely corrosive conditions, ideal for harsh applications. With this diverse material range, Guangxin meets the varied needs of clients across food, petrochemical, marine, aerospace, and nuclear industries.

Stainless Steel

Affordable, corrosion-resistant, versatile; suitable for general use and moderate chemical exposure. Lowest cost among the three.

Duplex Steel

Higher strength and corrosion resistance; excellent against chloride stress corrosion; mid-range cost between stainless steel and nickel alloys.

Nickel Alloy

Superior strength, corrosion, and heat resistance; ideal for extreme conditions. Highest cost due to advanced performance and materials.
