Our stainless steel flanges deliver secure, leak-tight connections for piping systems across oil & gas, chemical, and marine industries. This category encompasses weld neck, slip-on, blind, plate, socket welding, and threaded flanges in SS304, SS316L, carbon steel A105, and alloy grades. Each flange meets ANSI, GB, and DIN standards with precise bolt circle patterns, machined sealing surfaces, and pressure ratings from PN16 to PN40. Designed for easy assembly and reliable gasket compression, our pipe flange solutions accommodate diverse temperature and corrosion requirements.
Aseptic sanitary flange is made of eco-friendly SS304/SS316L stainless steel, used for hygienic pipeline connection. It features smooth surface, no dead ends, good sealing, and easy cleaning, widely applied in food, beverage, dairy, pharmaceutical and biotech systems.
This series includes durable flange sight glass with excellent corrosion resistance, made of stainless steel 304/316/316L and high‑strength tempered glass. Designed for observing fluid flow, liquid level, and working status in pipelines and tanks. Widely used in food, beverage, pharmaceutical, chemical, and water treatment industries.
This category includes high‑strength sterilizer flanges for food sterilizers, retorts, and pressure sterilizing equipment. Made of stainless steel 304/316L, they feature high pressure resistance, high temperature resistance, good sealing, and long service life. Compliant with food grade standards, widely used in food, beverage, pharmaceutical sterilization equipment, supporting customization.
These are stainless steel weld neck (WN) flanges, featuring a long, tapered neck that integrates with the pipeline via butt welding. The neck design ensures uniform stress distribution, making them ideal for high-pressure, high-temperature, and corrosive environments. Widely used in oil & gas, chemical, pharmaceutical, and power industry pipelines requiring long-term reliability.
The tube sheet is a critical component used in heat exchangers, boilers and pressure vessels to support and fix the tubes. Made of high-quality stainless steel or carbon steel, with precise hole machining, high strength and corrosion resistance. Widely used in chemical, petrochemical, power, food and pharmaceutical industries.
These are threaded (TH) flanges, designed with internal/external threads for bolt-free connection to threaded pipes. Available in three materials (stainless steel, carbon steel, alloy steel) to adapt to different pressure and corrosion conditions. They feature quick installation (no welding required), easy disassembly, and are widely used in low-to-medium pressure pipelines for oil & gas, water treatment, chemical, and municipal engineering.
Socket weld flanges are designed for high‑pressure piping systems, made of stainless steel 304/316. They feature high strength, good sealing, easy installation, and long service life. Widely used in petroleum, chemical, water treatment, and industrial pipelines. Compliant with ANSI, DIN, JIS standards, supporting customization and bulk orders.
These are stainless steel weld neck slip-on flanges (SO flanges), featuring a short neck design that balances structural strength and easy installation. Pipes slip into the flange bore and are welded for tight connection, with the neck enhancing stability. They offer excellent corrosion resistance and pressure resistance, widely used in oil & gas, chemical, water treatment, and medium-pressure industrial piping systems.
These are stainless steel slip-on flanges (PL flanges), a cost-effective flange type designed for easy installation—pipes slide through the flange bore and are welded on both sides. They feature good sealing performance, corrosion resistance, and wide compatibility, widely used in water supply, oil & gas, chemical, food, and general industrial piping systems.
These are stainless steel blind flanges (BL flanges) designed for closing the end of pipelines or pressure vessels. Featuring high corrosion resistance, strong structural strength and reliable sealing, they are widely used in petroleum, chemical, water treatment, food & pharmaceutical, and industrial piping systems to prevent fluid leakage and ensure system safety.
