Directly buried casing compensator
The sleeve compensator, called the tubular expansion joint, is a
compensation device for hot fluid pipeline, which is mainly used
for the auxiliary equipment of linear pipeline. It is suitable for
hot water, steam and grease media. Through the sliding movement of
the sliding sleeve to the outer sleeve, it can achieve the
compensation of thermal expansion.
Performance of directly buried casing compensator
1. Sleeve compensator is applicable to medium engineering pressure
≤ 2.5MPa and medium temperature - 40 ℃ ~ 600 ℃.
2. The sleeve compensator adopts a new sealing material flexible
graphite ring, which has the characteristics of high strength, low
friction coefficient (0.04 ~ 0.10), no aging, good effect and
convenient maintenance.

Note:Flange supply according to GB/T 9119-2000 standard ,also can
supply according to clients’other requirements.
Directly buried casing compensator advantage
The service life of sleeve compensator is long, and the fatigue
life is equivalent to that of pipeline. After special treatment,
the sliding surface has good corrosion resistance in brine, salt
solution and other environments, which is more than 50 times higher
than that of austenitic stainless steel. At the same time, when the
sealing effect is weakened due to wear after many years, the flange
can be tightened again to enhance the sealing performance, or the
bolt can be loosened, the pressure ring can be removed, and then
one or two layers of sealing rings can be installed to compress the
pressure ring and continue to be used.
Directly buried casing compensator application
Single way sleeve compensator is called tubular expansion joint and
pipeline expansion joint, which is the compensation device of hot
fluid pipeline, mainly used for the auxiliary equipment of linear
pipeline. It is suitable for hot water, steam, grease and other
media. Through the sliding movement of the sliding sleeve, the
thermal expansion compensation can be achieved.
