Import Flange — Buy in Bulk from Supplier in China

Shenghao Pipe Fittings Manufacturing Co., Ltd. supplies flanges conforming to ANSI B16.5 and ANSI B16.47 standards, with pressure ratings from CLASS 150 to CLASS 2500. These flanges are manufactured for use in high-pressure industrial environments and feature standardized bolt hole patterns, face types, and dimensional tolerances as defined by these specifications. The product range includes weld neck, slip-on, blind, and socket weld flanges, each designed for specific installation requirements and stress conditions.

The flanges are produced using carbon steel, alloy steel, and stainless steel grades such as A105, A182 F304, and A182 F316, selected based on corrosion resistance and temperature tolerance. Surface finishes include standard mill finish and optional smooth or serrated finishes for gasket compatibility. These material choices align with typical industry practice for oil and gas, chemical processing, and water treatment applications where exposure to aggressive media demands precise metallurgical properties.

Buyers in petrochemical, pharmaceutical, and heavy construction sectors use these flanges to create leak-tight joints in pipeline systems. Trade terms are typically FOB or CIF from Tianjin or Qingdao ports. Minimum order quantities are flexible and determined by project scale, but bulk orders often reduce per-unit logistics costs. Buyers should confirm material certification and dimensional inspection reports before shipment.

Shenghao Pipe Fittings Manufacturing Co., Ltd. operates from the Industrial Zone Mengcun in Cangzhou, Hebei, a known hub for pipe fitting production in northern China. The company is listed as an imported supplier with harbor trust tier, indicating verified export activity and compliance with basic customs documentation. There is no public data on years in operation, workforce size, or revenue. The listing confirms manufacturing capability but does not specify whether flanges are forged, cast, or machined from bar stock.

The supplier does not provide details on certifications beyond the standards referenced in product descriptions. No claims are made about in-house testing labs, client lists, or export volume. Response rate and average response time are not recorded, suggesting limited buyer communication infrastructure. Buyers should treat this as a manufacturer with documented export experience but unverified internal quality controls.
