常见问题
?Can an industrial rubber expansion joint be selected by DN and PN only?
No. DN and PN are not enough. Buyers also need medium, temperature, vacuum condition, movement, face-to-face length, supports and project standards.
?Is EPDM automatically suitable for drinking water?
No. Potable-water projects require the project specification, contact requirements, approval documents and contract requirements to be confirmed.
?What is special about pump suction service?
Pump suction may involve low pressure or vacuum risk, so the joint structure, material and installation conditions should be reviewed separately.
?Can axial, lateral and angular movement values be added together?
No. Movement values should not be added as simultaneous maximums. The usable range depends on structure, pressure, installation length and piping layout.
?Can a rubber expansion joint replace pipe anchors?
No. Anchors, guides and supports must be provided by the piping system. The joint should not carry valve, equipment or pipe weight.
?What should be included in a rubber expansion joint RFQ?
Include size, face-to-face length, flange standard, pressure, temperature, medium, vacuum condition, movement, supports, quantity, drawings and site photos.
