Tube Sheet Flange Product Introduction
The Tube Sheet Flange is a critical component used to connect pipelines with equipment (such as heat exchangers, boilers, pressure vessels, etc.), combining the support function of a tube sheet with the sealing and connection capabilities of a flange. It is widely used in industries such as petroleum and chemical processing, power generation, pharmaceuticals, and food processing, ensuring stable operation under high pressure, high temperature, or corrosive conditions.
Tube sheet flanges can be manufactured from a variety of materials to meet different operational requirements, including:
ASTM A105: Standard forged carbon steel flange material for general service.
Q235B/Q345R: Common Chinese grades for low-to-medium pressure applications.
ASTM A516 Gr.60/70: Pressure vessel-quality carbon steel for moderate temperatures.
304/304L (ASTM A182 F304/F304L): General-purpose austenitic stainless steel with good corrosion resistance.
316/316L (ASTM A182 F316/F316L): Enhanced corrosion resistance due to molybdenum, ideal for marine and chemical environments.
321 (ASTM A182 F321): Titanium-stabilized for high-temperature applications.
347 (ASTM A182 F347): Niobium-stabilized for improved intergranular corrosion resistance.
16Mn/16MnR: Chinese low-alloy high-strength steel for pressure vessels.
15CrMo/12Cr1MoV (ASTM A182 F11/F22): Chrome-molybdenum alloy for high-temperature and high-pressure service (e.g., power plants).
ASTM A182 F5/F9/F91: Heat-resistant alloys for extreme conditions.
2205 (S31803, ASTM A182 F51): Balanced austenitic-ferritic structure for high strength and chloride resistance.
2507 (S32750, ASTM A182 F53): Superior corrosion resistance for offshore and chemical processing.
Hastelloy® (C276/C22, ASTM B564): Excellent resistance to pitting and chemical attack.
Inconel® (625/600, ASTM B564): High-temperature oxidation and creep resistance.
Titanium (Gr.2/Gr.5, ASTM B381): Lightweight with outstanding corrosion resistance.
Monel® (400/K500): Nickel-copper alloy for seawater and acidic environments.
Flat Face (Plate) Tube Sheet Flange
Simple design, cost-effective, suitable for low-pressure applications (PN6-PN16).
Weld Neck Tube Sheet Flange
Reinforced neck for high-pressure (PN10-PN420), high-temperature, and vibration-prone systems.
Lap Joint Tube Sheet Flange
Detachable flange ring for easy assembly, ideal for systems requiring frequent maintenance.
Threaded Tube Sheet Flange
Internal threads for screw-on installation, used in small-diameter, low-pressure piping.
Custom Non-Standard Flanges
Tailored shapes (square, oval) or multi-functional designs for specialized equipment.
Pressure ratings comply with international standards (ANSI, DIN, GB, JIS, etc.), covering:
Low Pressure (PN6-PN16): Water treatment, HVAC systems.
Medium-High Pressure (PN25-PN100): Chemical processing, boilers.
High Pressure (PN160-PN420): Oil & gas pipelines, nuclear power plants.
Petrochemical: Heat exchangers, reactors, distillation columns.
Power Generation: Boilers, condensers, steam turbine systems.
Pharmaceutical & Food: Sanitary-grade stainless steel flanges meeting GMP/FDA standards.
Shipbuilding: Desalination units, engine cooling systems.
Environmental Engineering: Wastewater treatment, flue gas desulfurization.
