Frequently Asked Questions
What is stainless steel corrugated pipe?
Stainless steel corrugated pipe features annular or helical corrugations that provide axial flexibility, absorb thermal expansion, reduce vibration transmission, and increase flow turbulence for heat transfer enhancement. It is used in flexible couplings, exhaust flex joints, and compact heat exchangers.
What grades are used for stainless steel corrugated pipe?
Corrugated pipe is available in grades 304, 316L, and 321. Grade 316L is preferred for chemical and seawater service. Grade 321 is used for high-temperature exhaust and boiler applications rated up to 850°C continuous service.
What sizes are available for corrugated stainless steel pipe?
Corrugated pipe is available in OD from 6 mm to 2000 mm with wall thickness from 0.15 mm to 25 mm. Corrugation pitch ranges from 2–5 mm for heat transfer enhancement to 8–20 mm for high-flexibility and expansion-joint applications. Custom corrugation geometry engineered to pressure and flexibility requirements.
How much axial and angular flexibility does corrugated stainless steel pipe provide?
Corrugated stainless steel pipe typically allows axial compression and extension of 10–30% of free length and angular deflection of 5–30° depending on wall thickness and corrugation geometry. This makes it ideal for vibration isolation and compensating pipe misalignment.
What are the main applications for corrugated stainless steel pipe?
Key applications include residential and commercial gas flex connectors, marine and automotive exhaust flex joints, heat exchanger tubes for turbulent-flow enhancement, corrugated stainless steel tube (CSST) underground gas distribution, and industrial vibration-damping pipe connections.
