Tubing fitting:
Huiyuan siphon drainage system of tubing fitting adopting advanced hot modulus method horizontally rotating centrifugal casting process, dense degree is high, the bao hou evenly and convenient installation.
Can inherit from all sides vibration (including strong earthquake) tube hoop connection, make interface and firm and corrosion.
No chlamydia trachomatis and percolationless, no slag.
Service life of 100 years.

By corresponding heat treatment, and acid treatment, appearance is bright and clean and beautiful, corrosion resistance, good performance is negative pressure ability.
Especially suitable for confined to demand higher high-rise buildings and adornment effect have special requirements of buildings.
