6. FAQ (Frequently Asked Questions, Export Focused)
- Q1: Do your Stainless Steel Fittings comply with international standards? What does it include?
A1: Yes, all our Stainless Steel Fittings strictly comply with international industry quality standards, including material composition verification, dimensional accuracy control, environmental protection production processes, pressure-bearing safety performance, and traceability of product quality. This ensures our products meet the import requirements of global markets and pass relevant inspections smoothly, especially for high-hygiene and corrosive environment applications. - Q2: What is the difference between 304 and 316L stainless steel materials for Stainless Steel Fittings? How to choose?
A2: 304 stainless steel has good corrosion resistance, suitable for general corrosive media (such as weak acid, water) and normal temperature scenarios; 316L stainless steel contains molybdenum, with stronger corrosion resistance, suitable for strong corrosive media (such as seawater, strong acid and alkali) and high-temperature environments. Choose 304 for general industrial and civil pipelines; choose 316L for marine, chemical, and pharmaceutical pipelines. Both materials meet international standards. - Q3: Can you provide custom size, type or surface treatment for Stainless Steel Fittings?
A3: Yes, we support full custom services. We can produce non-standard sizes (beyond NPS 1/2″-48″/DN10-DN1200), custom types (e.g., special angle elbows, non-standard tees), and custom surface treatment (e.g., high-gloss mirror polishing, sandblasting). All custom products still comply with international specifications, as long as you provide detailed technical requirements. - Q4: What is the minimum order quantity (MOQ) for Stainless Steel Fittings? Do you provide samples?
A4: For standard specifications of Stainless Steel Fittings, the MOQ is 10 pieces; for custom specifications, the MOQ can be negotiated. We provide free samples (1-2 pieces) for quality inspection, and the customer only needs to bear the shipping cost. The sample lead time is 3-5 working days. - Q5: How to ensure the quality of your Stainless Steel Fittings?
A5: We have a strict quality control system: 1. Raw material inspection (material composition, mechanical properties, corrosion resistance test); 2. Production process inspection (dimensional accuracy, welding quality, forming quality); 3. Finished product inspection (pressure test, non-destructive testing, surface finish inspection); 4. All products are accompanied by MTC before delivery. - Q6: What payment terms and shipping methods do you accept for export orders?
A6: Payment terms: T/T (30% advance payment, 70% balance before delivery), L/C at sight, D/P, Western Union (flexible terms for long-term cooperative customers). Shipping methods: Sea freight (for large orders), air freight (for urgent orders), international express (for samples). - Q7: Can your Stainless Steel Fittings be exported to Europe, North America and other regions? Do you have relevant certificates?
A7: Yes, our Stainless Steel Fittings can be exported to Europe, North America, Southeast Asia, the Middle East and other global regions.We can provide MTC (Material Test Certificate), TUV, ISO and PED certificates required by the destination country, ensuring smooth customs clearance, especially for low-medium pressure and large-diameter industrial orders.
