Key features

Pipe plugging: No-drilling design, used to seal the end of pipes or equipment connections, with pressure ratings ranging from Class 150 to Class 2500 (PN20-PN420).

Suitable for various sealing surfaces: provides RF, FF, MFM, TG, RTJ sealing surfaces. The bolt holes can be interchangeably installed without the need to modify the pipeline.

Easy maintenance: It can be quickly disassembled and assembled. It is used for temporary or permanent blocking of pipelines, and is also used as a cover for purging, cleaning, and pressure testing.

High-precision machining: The roughness of the sealing surface is Ra<3.2 um; The bolt holes are processed by CNC, and the deviation between the holes and the mating flange is<0.2 mm.

Material traceability: Blind plate flanges are marked with the furnace number, material type, and pressure rating. Carbon steel undergoes normal heat treatment, while stainless steel undergoes solutio

Extra-large size capability: The production time for regular DN2000 type blind plates is 10-15 days; the delivery time for super-large DN3000 type blind plates is 25-30 days.

Customized Drawing Support: Full customization available based on customer drawings and specific design requirements. Offers suggestions for optimizing the structure of forgings.

24/7 Technical Support: Standard forgings (such as round bars, blocks) are delivered within 7 to 15 days; complex and irregular forgings within 20 to 30 days.

Forging process: The forging piece is processed by CNC turning to obtain a uniform grain structure, without burrs or cracks. The surface can be treated with anti-rust black paint, hot-dip galvanizing.

Reliable packaging and logistics: Export-grade rust prevention treatment (applying anti-rust oil / passivation / blackening) + wooden pallets / fumigated wooden crates / steel frame packaging.

AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier focused on forged products, flanges, mechanical components, and related pipeline products. It reports integrated capabilities covering forging, heat treatment, machining, testing, surface treatment, packaging, and shipment, with more than 10 production lines and stated annual outputs of 20,000 tons of flanges, 10,000 tons of forgings, and 10,000 tons of bearings. It provides 3D software design and multiple customization options. Quality controls include documented inspection instructions, raw-material traceability, complaint procedures, and corrective-action procedures. However, the provided information shows no new products in the past year, no ODM, OEM for popular brands, or SDK capability, and no overseas warehouse or showroom. Evidence of formal certifications, financial strength, and specific customer cases is insufficient.

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier and conducts forging manufacturing and mechanical component processing. Its product scope includes flanges, castings, fittings, pipeline accessories, valves, and related products, with specifications ranging from DN10 to DN5000.

After-Sales capabilityThe supplier states that it provides reliable after-sales service and has a clear, documented procedure for handling customer complaints, with records followed. Corrective and preventive-action procedures are also documented for service capability.

R&D capabilityThe supplier provides 3D software design and supports customization from samples and designs, including full, minor, and flexible customization. However, it reports no new products in the past year, no ODM service, and no available SDK, indicating that evidence for ongoing product innovation is limited and includes stated deficiencies.

Production capacityThe supplier reports integrated forging, heat treatment, machining, physical and chemical testing, surface treatment, packaging, and shipment capabilities, along with more than 10 production lines and in-stock capacity. Stated output includes 20,000 tons of flanges, 10,000 tons of forgings, and 10,000 tons of bearings, with lead times within 15 working days in both off-peak and peak seasons; however, it lacks a valid manufacturing contract with affiliated subcontractors.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, and also provides 3D software design services. This directly supports a broad customization capability.
