Frequently Asked Questions
Q1: Is this coil made of genuine 304 stainless steel?
A: Yes, the coil is manufactured from certified 304 stainless steel (UNS S30400). A Mill Test Report is provided with each shipment to verify the material composition and mechanical properties.
Q2: Can the coil be customized to different dimensions?
A: Absolutely. We offer customization in tube length, coil diameter, number of turns, and end connection types. Please provide your drawing or specifications for a tailored solution.
Q3: What is the maximum temperature the coil can handle?
A: The 304 stainless steel coil can operate continuously at temperatures up to 400°F (204°C), depending on the system pressure and environment. For higher temperature applications, please consult our engineering team.
Q4: Does the 250 PSI rating include a safety factor?
A: Yes, the coil is designed with a safety factor of 1.5. Each unit is hydrostatically tested at 375 PSI (1.5× working pressure) before leaving the factory.
Q5: How long is the warranty, and what does it cover?
A: The coil comes with a 1-year warranty against manufacturing defects in materials and workmanship. This includes issues such as leaks, cracks, or improper welds. Normal wear and tear or damage from misuse is not covered.
Q6: What is a Mill Test Report, and why is it important?
A: A Mill Test Report (MTR) is a document that provides the chemical analysis, mechanical properties, and heat treatment details of the stainless steel used. It is crucial for quality assurance, material traceability, and compliance with industry standards (e.g., food processing, pharmaceuticals).
Q7: Do you have stock for immediate shipment?
A: We maintain a reasonable inventory of standard sizes (e.g., 5/8" tube, 250 PSI) for quick delivery. For custom dimensions, lead time is typically 2–4 weeks depending on quantity.
Q8: Can this coil be used in ammonia refrigeration systems?
A: 304 stainless steel is generally compatible with ammonia, but we recommend verifying the specific operating conditions (temperature, pressure, moisture) with our technical team. For highly corrosive environments, we can also offer 316L stainless steel as an alternative.
