Frequently Asked Questions
-
Q: What is the difference between Schedule 40 and Schedule 80 pipe?
A: Schedule 40 has a thinner wall than Schedule 80. Schedule 80 offers higher pressure rating and thicker wall for more demanding applications, but Schedule 40 is more cost-effective and suitable for many standard pressure systems. -
Q: Can you provide custom lengths?
A: Yes, we offer customization. Standard length is 20 ft (6 m), but we can cut to your required lengths. Please specify your needs when placing an order. -
Q: Is the pipe suitable for high-temperature applications?
A: 304 stainless steel maintains good mechanical properties up to around 870°C (1600°F) in intermittent service, but continuous use above 425°C (800°F) is recommended with caution. Consult our technical team for specific temperature requirements. -
Q: Does the pipe come with a Mill Test Report (MTR)?
A: Yes, a Mill Test Report is included with every shipment, providing chemical composition and mechanical property data for full traceability. -
Q: What surface finishes are available?
A: Standard finish is annealed and pickled (2B). A No.1 finish (hot-rolled, annealed, and pickled) is also available. Please specify your preference. -
Q: Can this pipe be used for drinking water systems?
A: Yes, 304 stainless steel is FDA-approved for food contact and is commonly used in potable water systems due to its corrosion resistance and non-toxic properties. -
Q: What is the warranty policy?
A: We offer a 1-year warranty covering manufacturing defects. If any defect is found, we will replace or refund the product upon inspection. -
