Frequently Asked Questions (Technical Q&A)
Q1: What is the difference between SS 304 and SS 316 hose barbs for marine applications?
A1: SS 316 contains 2-3% molybdenum providing superior resistance to chloride-induced pitting and crevice corrosion, making it essential for saltwater and marine environments where SS 304 may experience localized corrosion.
Q2: Can your hose barbs handle cryogenic applications?
A2: Yes, our austenitic Stainless Steel hose barbs maintain excellent toughness and ductility at cryogenic temperatures down to -196°C (liquid nitrogen temperature), with no brittle transition temperature.
Q3: What thread sealants are compatible with Stainless Steel hose barbs?
A3: Compatible sealants include PTFE tape, anaerobic thread compounds, and pipe dope formulated for Stainless Steel. Avoid zinc-containing compounds that may cause galvanic corrosion.
Q4: How do you prevent galling during installation of Stainless Steel threaded fittings?
A4: Use appropriate anti-seize compounds, control installation torque, ensure proper thread engagement, and avoid cross-threading. Our fittings feature chamfered thread starts to minimize installation issues.
Q5: What is the maximum pressure rating for your high-pressure hose barbs?
A5: Our high-pressure series achieves working pressures up to 6000 PSI (414 bar) depending on size and configuration, with safety factors of 4:1 minimum and 100% pressure testing verification.
Q6: Are your sanitary hose barbs validated for pharmaceutical use?
A6: Yes, our sanitary grade fittings comply with FDA 21 CFR 177.2600, USP Class VI biocompatibility, cGMP requirements, and include material certifications with full traceability.
Q7: What quality certifications do you provide with shipments?
A7: Each shipment includes Material Test Certificates (MTC) per EN 10204 3.1, dimensional inspection reports, pressure test certificates, and chemical composition analysis from accredited laboratories.
Q8: Can you customize hose barb configurations for OEM applications?
A8: Absolutely. We specialize in custom configurations including non-standard thread specifications, unique geometries, special materials, and private labeling with customer logos and part numbers.
Q9: What is your typical turnaround time for standard vs. custom orders?
A9: Standard catalog items ship within 4-6 weeks. Custom configurations require 6-8 weeks depending on complexity. Rush orders can be accommodated with premium scheduling.
Q10: How do you ensure dimensional accuracy across production batches?
A10: We employ statistical process control (SPC), coordinate measuring machines (CMM) for inspection, calibrated tooling, and first-article inspection protocols to maintain consistent dimensional accuracy within specified tolerances.
