A Universal Expansion joint is an assely containing two bellows connected by a centre pipe and equipped with tie rods. Universal Expansion joints are mainly used to absorb any coination of the three basic movements in the piping system. (Axial, Lateral
Lateral expansion joints are suitable for the absorption of lateral movements, i.e. transversely to the pipe axis of the expansion joint. absorption of lateral movement one-way flexibility with single pivot bolt bracing universal flexibility with cardan joint bracing

• good pipe alignment during assely of a pipe run prevents ‘locked-in’ stress • the use of expansion (mechanical) joints, such as dresser-type joints, is restricted to loions where pipes move because of thermal expansion or contraction, or ship bending.
Metallic Expansion Joints Metallic Expansion Joints are installed in pipe work and duct systems to prevent damage caused by thermal growth, vibration, pressure thrust and other mechanical forces. There is a wide range of metallic bellows designs in a variety of Puhui Pipe manufacturer in China
The fire protection pipe and connection fittings are mainly used to connect firefighting equipment, conveying fire fighting water and so on. It is also called fire sprinkler pipe and fittings. Due to the special requirements, the thickness and material of the fire protection Puhui Pipe manufacturer in China

Standard cut grooved pipe will provide double the expansion/contraction or deflection capabilities of the same size standard roll groove pipe. The angular deflection available at a Victaulic flexible grooved pipe joint is useful in simplifying and speeding installation.
How to use it Simple steps for reliable and defined results. The electromechanical tool press the joint on the pipe through its jaws. The connection is permanent and not reversible and permanent. Pressing parameters such as pressure strengh and time.
