ZP type Straight pipe pressure balance corrugated expansion joint
Product description
Straight pipe pressure balanced corrugated expansion joint is mainly used to compensate the axial displacement of the piping system. It has the advantages of simple design, large compensation amount, no internal pressure thrust, etc., but the price is higher.It is mainly used in large-caliber straight pipe systems that are not easy to set.
Application
In actual engineering projects, there are many ways to absorb thermal expansion stress on the pipe gallery, which are mainly divided into natural compensation (square compensator) and bellows expansion joint compensation (pressure balanced expansion joint, lateral large tie rod compensator, rotation compensationOrgan section, etc.)In extreme cases, when the pressure of the pipeline is small and there is no space to set the natural compensation bend, a bellows expansion joint can be added to the pipe system to increase flexibility.Great flexibility.ZPB type straight pipe pressure balance corrugated compensator is durable and has a long service life. The product is widely used in water, electricity, environmental protection, metallurgy and other large enterprises.
Structure introduction of straight pipe pressure balance corrugated expansion joint
The design basis of bellows expansion joints is based on China's GB / T12777-2008 "General technical conditions for metal bellows expansion joints."Temperature range of metal expansion joints: The bellows of general expansion joints are made of thin-walled austenitic stainless steel (304, 304L, 316, 316L).When the material of the tube and the liner is carbon steel, the operating temperature range of the expansion joint is -20 to 420 ℃; when the material of the bellows, the tube and the liner is stainless steel, the operating temperature range of the expansion joint is-196 to 700 ° C.When the medium contains corrosive liquids, the lining cylinder is made of nickel-based alloy (In-conel625, Inconel600), and the operating temperature range of the expansion joint is -196 to 650 ° C.
Straight Tube Pressure Balanced Expansion Joint (ZP Type)When the main fixed support cannot be provided to absorb the axial displacement of the straight pipe section, a straight pipe pressure balanced corrugated compensator and a bypass axial pressure balanced corrugated compensator can be considered.If the internal pressure thrust of the system is not large enough than the stiffness force, it is not recommended to consider economic factors.
Working principle of straight tube pressure balanced expansion joint
Straight tube pressure balanced expansion joints are divided into two types: internal pressure and external pressure. This type of expansion joints are composed of two sets of working waves and a set of balanced waves. Straight tube pressure balanced expansion joints are mainly used to compensate axial displacement.The expansion joint withstands the internal pressure thrust of the pipeline through the interaction of working waves and equilibrium waves.And its compensation range can reach up to 500 mm, much larger than the internal pressure of 100 mm, so in the project we use external pressure straight pipe pressure balance expansion joints to absorb large axial displacement of the pipeline.
