C68700 Aluminum Brass Tube PDF
Products Description
Aluminium brass tubes have a combination of high strength and general corrosion resistance, as well as a low susceptibility to stress corrosion cracking, makes it a preferred choice for a variety of applications. The tubes may also be heat treated and utilised in hard drawing circumstances, ensuring that they are stress corrosion fracture free. These ASTM B135 UNS C68700 SMLS tubes are used in various application industries like Petroleum, chemical, power, gas, water, metallurgy, shipbuilding, construction, etc.

How To Test Astm B111 C68700 Tubes
Ensuring the quality and reliability of ASTM B111 C68700 Tubes is crucial. Here are some common testing methods:
Hydrostatic testing: Checks for leaks and verifies the tube's ability to withstand pressure.
Ultrasonic testing: Detects internal flaws or defects that could compromise performance.
Eddy Current testing: Evaluates the tube's surface and subsurface integrity.
Mechanical testing: Measures tensile strength, hardness, and elongation to ensure compliance with ASTM standards.
Material Applications
C68700 is primarily used in fields with extremely high requirements for resistance to seawater corrosion and biofouling, especially as condenser and heat exchanger tubing:
Marine and Marine Engineering: Condenser tubes for marine power plants, seawater cooler tubes for ships, seawater piping systems, pump and valve components, heat exchanger tubes, and outboard fittings.
Power Industry: Condenser tubes, low-pressure heater tubes, and oil cooler tubes for coastal thermal power plants and nuclear power plants.
Seawater Desalination: Condenser tubes in the heat recovery and heat discharge sections of multi-stage flash (MSF) units.
Petrochemical Industry: Heat exchanger tubes and cooler tubes for seawater cooling.
Refrigeration and Air Conditioning: Heat exchanger tubes in some refrigeration systems with high corrosion resistance requirements.
Marine Aquaculture Equipment: Seawater transport pipelines and heat exchange components.
