Frequently Asked Questions
Q: What industries typically use these fittings?
A: Common applications include chemical processing plants, food/beverage production lines, pharmaceutical manufacturing, and offshore oil platforms.
Q: Are these fittings compatible with high-temperature steam?
A: Yes, 304 stainless steel maintains integrity at continuous operating temperatures up to 400°C (752°F).
Q: Can I order non-standard sizes?
A: Custom diameters and thread configurations are available upon request with standard lead times.
Q: What welding methods are recommended?
A: TIG welding is preferred for critical applications, though MIG and stick welding are acceptable alternatives.
Q: How does 304 stainless compare to 316 grade?
A: While both offer excellent corrosion resistance, 316 contains molybdenum for enhanced protection against chlorides – suitability depends on specific media.
Q: Do you provide material certification?
A> Mill test reports verifying chemical composition and mechanical properties are available with purchase.
Q: What's the maximum pressure rating?
A> Ratings vary by size (see table), with smaller fittings handling up to 3000 PSI at ambient temperatures.
Q: How should I store these fittings before installation?
A> Keep in dry, covered storage with thread protectors installed to prevent damage or contamination.
