Sleeve expansion joints are primarily used for axial compensation in overhead pipelines, and can also be used in directly buried pipelines to absorb axial expansion and contraction caused by temperature differences.
Sleeve expansion joints are primarily used for axial compensation in overhead pipelines, and can also be used in directly buried pipelines to absorb axial expansion and contraction caused by temperature differences. They are widely used in urban heating, metallurgy, mining, power generation, petroleum, chemical, and construction industries.
Sleeve expansion joints utilize a composite sealing structure of high-quality molded packing and semi-solid sealing oil.
This results in excellent sealing performance, high temperature resistance, corrosion resistance, and the ability to plug leaks under pressure, ensuring long-term stable operation of pipelines.
| I. Scope of Application: The ZTB-B type sleeve compensator, designed and manufactured according to CJ/T30161.2, is mainly used for axial compensation of overhead pipelines. It can also be used for directly buried pipelines to absorb axial expansion and contraction caused by temperature differences. It is widely used in urban heating, metallurgy, mining, power generation, petroleum, chemical, and construction industries. II. Product Features: This model of compensator adopts a composite sealing structure of high-quality molded packing and semi-solid sealing oil. It has the advantages of good sealing performance, high temperature resistance, corrosion resistance, and the ability to plug leaks under pressure, ensuring long-term stable operation of pipelines. |
