Charlotte Pipe Company – “The Pipe Whisperer”

According to the ASTM and CISPI standards, only the foundry that casts the pipes and fittings can assure the purchaser that the quality control procedures required by the product standards were complied with at the time the material was cast. The standards prohibit examination or test of the physical, chemical or raw material properties after the time of manufacture as proof of compliance. Third party certifiers or inspectors claiming to certify compliance must conduct these examinations at the point of manufacture as the products are made.
