Studded Tube ASTM A312 TP316L For Heat Exchanger
Studded Tube ASTM A312 TP316L For Heat Exchanger
Product Description
Engineered for aggressive shell-and-tube exchangers, this studded tube starts with low-carbon 316L seamless stainless steel to ASTM A312, then carries rows of automatically welded studs that triple the gas-side surface and trigger intense turbulence. Even at 650 °C in sour flue gas or acid condensate, the molybdenum-bearing, extra-low-carbon grade resists pitting, crevice and intergranular attack, delivering five-fold life versus carbon-steel alternatives. The result is reliable duty in refinery FCC, offshore platform, LNG liquefaction, fertilizer and waste-to-energy heat-recovery trains.
Applications
- Chemical industry: Used in reactors, condensers and evaporators
- Oil and gas: For heat exchangers, heaters and coolers
- Food and pharmaceutical: For sanitary heat exchange equipment
- Power industry: Used in boilers and waste heat recovery systems
TP316L stainless steel has excellent corrosion resistance to chloride and acidic environments.
Suitable for high temperature environments.
Good tensile strength and durability.
The nail head design increases surface area and improves heat exchange efficiency.
- Material Certificate: Check for compliance with ASTM A312/ASME SA312 standards
- Weld quality: Verify the weld quality of the nail head by non-destructive testing, such as ultrasonic or X-ray inspection
- Size inspection: Ensure that the size of the base tube and nail head meet design requirements
- Pressure test: Perform water pressure or air pressure test to ensure tightness and strength
