Import Blind Flange 1 — Buy in Bulk from Supplier in China

The Blind flange 1 from Xushui Hengxin Flange Manufacturing Co., Ltd. is a pressure-sealing component designed for end-of-line pipe termination in industrial systems. It is manufactured from carbon steel conforming to ASTM A105 and ASTM A350 LF2 standards, with nominal sizes ranging from ½ inch to 160 inches and pressure ratings up to Class 2500. The flanges are machined to ASME B16.5 and ASME B16.47 dimensional tolerances, ensuring interchangeability with standard piping systems across global installations.

Material composition follows standard carbon steel grades with controlled carbon and manganese content for weldability and mechanical strength. Surface finish is typically mill scale or optional sandblasted, with no coating applied unless specified. These flanges are not plated or galvanized, as their use in high-pressure environments requires base metal integrity. Typical applications include temporary shutdowns, hydrotesting, and maintenance isolation in pipelines where flow must be fully blocked.

Buyers in oil and gas, water treatment, and chemical processing industries source these flanges for system integrity during maintenance cycles. Packaging is bulk steel banding or wooden crate, depending on size and order volume. Trade terms are typically FOB Tianjin or CIF destination, with lead times averaging 30 to 45 days after deposit. MOQ is flexible but depends on size and pressure class; buyers should confirm exact requirements with the supplier before placing orders.

Xushui Hengxin Flange Manufacturing Co., Ltd. operates from Guangmen Industrial Zone in Xushui County, Hebei Province, China. The company specialises in carbon steel and alloy steel flanges for industrial piping systems, with production capacity focused on medium to large diameter products. The listing confirms the supplier is verified by harbor-level trade checks but provides no details on workforce size, annual output, or client list.

No certifications such as ISO 9001, PED, or API 6A are stated in the source data. The supplier has no recorded response rate or average response time, indicating limited engagement on the platform. Buyers should request third-party inspection reports and material test certificates directly before ordering, as these are not automatically provided.
