Buy & Import Flange from Wenzhou Wurong Valve Co., Ltd - Wholesale Supply

The flange supplied by Wenzhou Wurong Valve Co., Ltd is rated for a working pressure of 1000 psi and operates within a temperature range of -20°F to +232°F. It is designed with a BV-1000 WOG configuration, indicating compatibility with water, oil, and gas applications under high pressure. The product is constructed from industrial-grade carbon steel, though the exact alloy standard is not specified in the listing. This flange is engineered for durability in demanding environments where leakage prevention is critical.

The BV-1000 WOG designation suggests compliance with industry benchmarks for valve and flange pressure ratings, though it is not an official standard like ASME or API. The material likely aligns with ASTM A105 or equivalent, but no certification is confirmed. Typical wall thicknesses for 1000 psi flanges range from 0.5 to 1.25 inches depending on size, with bolt hole patterns following ANSI B16.5. Surface finish is not stated but is likely machined to standard sealing tolerances.

These flanges are commonly sourced by contractors in oil and gas, water treatment, and heavy manufacturing sectors that require reliable connection points. Buyers typically need compatibility with existing piping systems and verified pressure ratings. Trade terms include FOB and CIF shipping from Zhejiang port, with packaging designed for export. Minimum order quantity is not disclosed and must be confirmed with the supplier.

Frequently Asked Questions About Flange from Wenzhou Wurong Valve Co., Ltd
BV-1000 WOG indicates a working pressure rating of 1000 psi for water, oil, and gas applications. This is an industry term, not an official standard like ASME. Buyers should confirm whether this rating was tested under ASME B16.34 or similar, as actual performance depends on material, wall thickness, and temperature.

Sourcing Flange from Wenzhou Wurong Valve Co., Ltd - China Import Guide

Verify the BV-1000 WOG rating is supported by documented pressure testing, not just claimed. Request material test reports for carbon content, tensile strength, and impact resistance. Confirm the flange type (weld neck, slip-on) and face finish against your piping drawings. Do not rely on vendor descriptions alone - insist on third-party documentation for critical applications.

Lead time is not stated; confirm production and shipping schedules in writing. Incoterms are FOB or CIF, but clarify whether port charges, insurance, and import duties are included. Payment terms are not listed; negotiate for 30% deposit and balance against bill of lading. Ensure packaging includes desiccants and anti-rust paper, especially for long sea voyages.

Conduct incoming inspection for dimensional accuracy, surface cracks, and bolt hole alignment. Use a torque wrench to check bolt preload during installation. Verify that each flange has a heat number stamped on it for traceability. Request packing lists with batch numbers matching material certificates. Ensure customs documentation includes correct HS code 7307.21 and declares pressure rating for compliance.
