ASME/ANSI/DIN/GOST/BS En Blind Flange
This blind flange is a forged steel closing component designed for critical sealing applications in pipelines and pressure systems. It is manufactured in Carbon Steel A105, Stainless Steel 304/316, and Alloy Steel, with pressure ratings spanning 150# to 2500# and size ranges from 1/2" to 48". The flange meets ASME/ANSI, DIN, GOST, and BS EN standards, offering Raised Face (RF), Flat Face (FF), and Ring Joint (RJ) facing options to suit diverse industrial requirements.
The material selection includes Carbon Steel A105, RSt37.2, C22.8, and Q235 for carbon grades, while Stainless Steel 304/304L, 316/316L, and 321 are available for corrosion-resistant applications. Typical industry standards for blind flanges include ANSI B16.5, DIN EN 1092-1, and BS 4504, with common dimensions and tolerances adhering to these codes. The production process involves raw material cutting, heating, forging, heat treatment, machining, inspection, and cleaning to ensure structural integrity and surface finish.
Blind flanges are widely used in oil and gas pipelines, petrochemical plants, water treatment facilities, and power generation systems to terminate pipe ends or isolate sections for maintenance. Buyers typically source these for MRO supply or large-scale import/export projects, with applications ranging from linepipe systems to heat exchangers. Trade terms often include confirmation of pressure class compatibility, material test certificates, and compliance with project-specific standards such as API 605 or ASME B16.47.

Sourcing ASME/ANSI/DIN/GOST/BS En Blind Flange from Jinan Ruidong Flow Co., Ltd. - China Import Guide
Before ordering, verify the blind flange’s material grade, pressure class, and size compatibility with your pipeline system. Confirm that the supplier’s manufacturing standards (e.g., ASME B16.5, DIN EN 1092-1) align with your project’s specifications, and request third-party inspection reports if required by your industry or local regulations. For critical applications, such as oil and gas or chemical processing, ensure the flanges meet additional standards like API 605 or ASTM A105.
Discuss logistics details with Jinan Ruidong Flow Co., Ltd., including packaging, labeling, and shipping methods to prevent damage during transit. Clarify lead times, which can vary based on custom specifications or bulk orders, and confirm Incoterms such as FOB, CIF, or CFR to define responsibilities for shipping, insurance, and customs clearance. Payment terms, such as TT (Telegraphic Transfer) or LC (Letter of Credit), should also be negotiated upfront to avoid delays.
Conduct quality checks upon receipt, including visual inspection for surface defects, dimensional verification against certified drawings, and material composition tests using PMI (Positive Material Identification) for critical applications. Request hydrostatic or pneumatic pressure tests if the flanges will be used in high-pressure systems. Ensure all documentation, including MTRs, CoCs, and packing lists, is complete and matches the order specifications before acceptance.
