FAQ
Q: When is light gauge stainless steel pipe a suitable choice?
A: For general conveying, equipment connections and piping systems that do not require heavy-wall pressure-service pipe, light gauge tubes offer lower weight and can make handling, piping layout and installation more convenient.
Q: Is a thinner wall always better for light gauge stainless steel pipes?
A: No. Wall thickness should still be selected according to pipe diameter, connection method, service conditions and project requirements. A thinner wall should not be selected simply to reduce material consumption.
Q: Can light gauge stainless steel pipes be supplied in cut lengths?
A: Yes. Cut lengths and end requirements can be confirmed according to the piping layout, reducing the need for additional cutting and adjustment at the installation site.
