Second, product generation of note:

Pd /HZPP-DN * n-J (F)

H: This company inflates the festival code number; ZPP: Side ascending pipe pressure balance;

Pd: Design pressure (kgf/cm2); DN: The nominal passes the diameter (mm);

N: Wave number sum; J (F): The joint pattern (J takes over control, F flange)

Third, product unique feature:

1. has the absorption intrinsic pressure thrust force the ability, the nature compares ZP to be superior;
2. rigidities small, the guidance are good;
3. external dimensions small, the efficiency is good;
4. products installments with an improper method tropism request.

Fourth, installs the use matters needing attention:

1. for the reduced elastic reaction, the product has made 50% pre- stretch, installs when does not need again pretension;
When 2. installs under, pays attention to the sparse drainage opening to have to face;
After 3. scenes install, must the small tension bar demolision.
