Second, product generation of note:

Pd/HZP (SK) -DN ×n - J (F)

H: This company inflates the festival code number; ZP: Ascending pipe pressure balance; SK:S double-decked K armor link (structure pattern);

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:

This inflation festival beginnings and ends respectively have a work corrugated pipe, middle has a balanced corrugated pipe, the inflation festival (big tension bar or reed pipe) withstands the intrinsic pressure thrust force through the stress component among, therefore only needs the fixed support. This kind of inflation festival only can absorb the axial displacement.

Fourth, installs the use matters needing attention:

1. this kind of inflation festival general application on the impractical straight pipeline, the level installs.
After 2. inflations festivals install, all small tension bars must demolish.
3. for the reduced inflation festival to the support elastic reaction, may the kind of inflation festival carry on pretension or the precompression regarding this before the installment (above passable adjustment small tension bar realization).
