AWWAC200 refers to the standard established by the American Water Works Association (AWWA), which specifies the design, manufacturing, and installation requirements for spiral welded steel pipes used in potable water transmission systems.
Spiral welded pipes are tubular products formed by helically winding steel plates and welding them together. According to the AWWAC200 standard, these pipes are suitable for applications including potable water transmission, irrigation, water supply and drainage, heating, air conditioning, and gas distribution.
The AWWAC200 standard stipulates requirements for:
Dimensional ranges
Material specifications
Manufacturing processes
Chemical composition
Mechanical properties
Testing procedures
Surface treatment
It mandates manufacturers to use high-quality steel materials and conduct comprehensive inspections throughout production to ensure pipe quality.
Spiral welded pipes are high-strength, corrosion-resistant, and temperature-resistant materials widely used in:
Potable water transmission
Oil and gas transportation
Chemical substance conveyance
