Henan Liwei Industry Co.,Ltd, Production of gland loose tube type expansion joint is a kind of new type pipe connection and device to connect the connection device. Of course, the advantages of this scaling street is more than just connection effect, because of a certain displacement of the joint adjustment in the late work assignments, through the axial thrust, for the work of the whole pipeline system can reach a size adjustment, the adjustment at the same time also can protect the pipes are not damage.Many different kinds of the adjustment joint, according to the way links and divided into different interfaces.Gland loose tube type expansion joint and other interface is different, is mainly used in an auxiliary compensation effect.As a compensation tool, in the engineering of pipeline operation is essential.Gland loose tube type expansion joint and other scaling the difference is that the joint installation is very simple and quick, do not need to welding or other interface mode, structure is also very suitable for work.But it is important to note that the joint is strongly influenced by environmental temperature, during the installation process should consider the problem.
