Flanges connect pipes and valves with bolted seals for easy installation and maintenance. Used in oil, gas, and chemical industries under demanding conditions.

Pipe fittings connect, divert, and control pipeline flow. Made from carbon or stainless steel, types include elbows, tees, couplings, reducers, and plugs , etc.

LSAW pipes are longitudinally welded, offering large diameters and high pressure capacity for oil/gas pipelines and marine structures.

ERW pipes are formed by rolling and resistance welding steel strips, offering cost-effective, versatile sizes for oil/gas, water, and structural uses.

Carbon steel pipes, seamless or welded, provide strength and cost-efficiency but need coatings for corrosion resistance in harsh conditions.

Alloy steel pipes achieve higher strength, pressure ratings, and corrosion resistance through the addition of various alloying elements.

Stainless steel pipes offer excellent corrosion resistance and durability, making them suitable for applications in chemical, food, and medical industries.

Galvanized pipe, via hot-dip or electroplating, adds a zinc layer to steel for strong corrosion resistance. Used in water supply, HVAC, and low-pressure systems

High-pressure pipelines, made from alloy steel via seamless rolling, ensure safety in energy, chemical, and industrial systems under extreme conditions.

Mechanical pipe features high precision and high strength, making it widely used in mechanical manufacturing, hydraulic systems, and other applications.

LTCS pipes ensure toughness and crack resistance at -46°C to -196°C, vital for LNG and cold-region oil/gas applications.

Structural steel pipe offers high strength-to-weight ratio and design flexibility, widely used in buildings, bridges, and industrial frameworks.

Boiler tubes, made of heat-resistant steel, ensure safe heat transfer and pressure containment in high-temperature systems like power plants.

Torque tubes, made of galvanized steel or aluminum, connect and rotate solar panels for optimal sun tracking, ensuring structural stability and efficiency.

API Tubing, made of high-strength steel, transports oil/gas from wells with corrosion resistance and quick-connect design for efficient installation.
