Product Introduction

The injection type sleeve compensator, also known as the tubular expansion joint, is a compensation device for thermal fluid pipelines. It compensates for thermal expansion by sliding the outer sleeve through the sliding motion of the sliding sleeve. It is mainly used as an auxiliary device for linear pipelines. Suitable for hot water, steam, and oily media.

Product advantages

The injection filled sleeve compensator adopts a new type of sealing material flexible graphite ring, which has the characteristics of high strength, low friction coefficient (0.04~0.10), no aging, good effect, and easy maintenance.

The service life of the injection type sleeve compensator is long, and its fatigue life is comparable to that of pipelines. The sliding surface has undergone special treatment and has good corrosion resistance in environments such as salt water and salt solutions, which is more than 50 times higher than austenitic stainless steel. At the same time, if the sealing effect weakens due to wear and tear after many years, the flange can be tightened again to enhance the sealing performance. Alternatively, the bolt can be loosened, the pressure ring can be removed, and one or two layers of sealing rings can be installed to tighten the pressure ring and continue to be used.
