6. FAQ (Frequently Asked Questions, Export Focused)
- Q1: Do your Carbon Steel Fittings comply with international standards? What does it include?
A1: Yes, all our Carbon 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. - Q2: What is the difference between A105 and A234 WPB carbon steel materials for Carbon Steel Fittings? How to choose?
A2: A105 is forged carbon steel, suitable for high-temperature (up to 425℃) and medium-pressure pipeline systems; A234 WPB is seamless carbon steel, suitable for low-medium temperature and low-medium pressure systems, with better weldability. Choose A105 for high-temperature scenarios (e.g., power plant pipelines); choose A234 WPB for general industrial pipelines (e.g., water supply, chemical pipelines). Both materials meet international standards. - Q3: Can you provide custom size, type or surface treatment for Carbon 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., hot-dip galvanizing). 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 Carbon Steel Fittings? Do you provide samples?
A4: For standard specifications of Carbon 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 Carbon Steel Fittings?
A5: We have a strict quality control system: 1. Raw material inspection (material composition, mechanical properties); 2. Production process inspection (dimensional accuracy, welding quality, forming quality); 3. Finished product inspection (pressure test, non-destructive testing); 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).
