Directly buried type corrugated compensator
Directly buried type corrugated compensator is mainly used for buried pipeline axial compensation, have bending ability, so don't consider the effect of pipe sinking, products have a large amount of compensation, long life characteristics.
Model: DN32 - DN1600
The level of pressure: 0.25 Mpa to 2.5 Mpa
Product axial offsets: 30 mm - 500 mm

The use of direct buried corrugated compensator
Directly buried type corrugated compensator is mainly suitable for axial compensation, at the same time it has strong bending ability, so don't consider the effect of pipe sinking. Directly buried type wave compensation case and guide sleeve to protect the free expansion compensation, other properties with the ordinary corrugated compensator is the same.

Directly buried type corrugated compensator installation using the matters needing attention
Directly buried corrugated compensator is required between two fixed bearing this only a ripple compensator, the compensator for the calculation of bearing force and the unitary corrugated compensator for the calculation of bearing force is the same, due to the pressure in buried corrugated compensation has freedom in the line compensation and installation is simple wait for a characteristic, thus deeply engineering design and installation of the user's welcome.

Directly buried type corrugated compensator model example


Directly buried type corrugated compensator of the thermal deformation calculation
Delta L = a. t. L = 0.0133 x 360 x 30 = 143.6 mm
Note: a is carbon steel usually adopt coefficient of expansion
T for the pipeline medium temperature - when installation environment temperature
L as the length between two fixed bracket.

Directly buried type corrugated compensator installation considerations
1, for the directly buried corrugated compensator is compensation effect, must set a fixed bracket on both ends of the compensator, prevent the pipeline from internal pressure thrust affected by offshoring.
2, one end of the compensator (one-way compensation directly buried type compensator dead end) is near the end of the fixed bracket, with live head compensation pipeline compensator.
3, according to the amount of compensation to set the distance of two fixed bracket, the compensation is generally not greater than the pipe diameter.
4, in the process of pressure testing to compensator can not stretch.
