Laboratory for testing plastic pipes and fittings is the national lab professionally engaging in testing and studying the performance of plastic pipes and fittings.Now it has been equipped by the most advanced testing system with most expericeced engineers so as to become the largest systematical lab studying on the testing and evaluation of the plastic pipe in Asia.

　　Various kinds of standards such as GB,ISB,EN,DIN,ASTM,AS JIS,BS,manufacture standards,etc.,can be followed in this lab.All kinds of the tests of plastic pipes,such as hydrostacic pressure tests, burst strength tests,fatigue lests,creep tests,certain dynamic mechanical tests,PCP test, Thermal cCycling tests,long-term hydrostatic strength of thermoplastice materials in pipes form by extrapolation,etc.,can be carried out in this lab.

　　The lab has more than 2000clients.
　　The lab has been an authorized testing organization for safety inspection and accreditation of Buried pllyethylene pipes for the supply of Gaseous Fuels by China state bureau of Quality and Technical Supervision(CSBTS) and for productiong registration and permit issue by the construction commitments in the main provinces in China.
