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.

Technical data of directly buried casing compensator

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.
