five) CZPT standard (ISO 4422, ISO 3633, En BS 1452)



one.Corrosion resistance, impregnable for corrosion soil and different types of water for daily life, higher efficiency to inorganic acid, alkali, salt in corrosion resistance, suitable for excellent industrial sewage discharge and transportation.

2.Ageing resistance and extended services lifestyle, and the standard services daily life is about 30-fifty a long time. It is the developing drainage, sewage perfect supplies.

3.Shock resistance is sturdy, large mechanical strength.

four.Not straightforward to clog, no fouling, smooth inside, little fluid resistance, roughness coefficient is .009, unhindered stream, little servicing.

five. Not out of the rust water, making certain external do not rust, resist the oxygen index is substantial, with self-extinguishment.

6. Light bodyweight, for iron 1/10, handling and installation are practical, comparing to cast iron pipe improve efficacy 40-60%, certainly lessen undertaking expense.

7. Pipeline swell factor is little, thermal conductivity and elastic modulus is small, and it has outstanding drain freezing resistance efficiency when compared with iron pipe.

eight.Using distinctive auxiliary, avoid termites, pet biting injury.

9.CZPT assortment of goods, can cooperate with a variety of layout and installaion standarsd.
