Made of high-grade SS304/SS316 stainless steel via lost-wax investment casting, dense internal structure, excellent corrosion and acid resistance for harsh working conditions.
The precision investment casting process achieves high dimensional accuracy and fine surface finish, effectively reduces post-machining allowance, and lowers production cost.
An integral two-step reducing structure provides a transition connection between different pipe diameters or between equipment and pipelines, with strong versatility.
All sealing surfaces and bolt holes are precision CNC machined, with strict flatness and dimensional tolerance control, ensuring reliable zero-leakage sealing under high pressure.
Standard bolt hole distribution, compatible with ANSI, DIN, GB, and other mainstream flange standards, is convenient for on-site pipeline assembly and replacement.
The one-piece casting structure, without welding seams, stably withstands high pressure and impact loads, with no risk of fracture or leakage during long-term operation.
Smooth internal flow channel, low fluid resistance, reduces pipeline pressure loss and improves medium conveying efficiency.
Strict full-process quality control, non-destructive testing, and hydraulic pressure testing for each piece eliminate casting defects and guarantee stable batch quality.
Strong customization capability, producing flanges of various sizes, pressure ratings, and structures strictly according to customer drawings and requirements.
Wide application range; widely used in pump-valve matching, the chemical industry, water treatment, hydraulic systems, and other industrial pipeline projects.

AI-Powered supplier vetting
SummaryThe supplier presents itself as an ODM/OEM partner serving power generation, water treatment, petrochemical, and industrial automation markets. It reports flexible customization, 3D design services, recent product development, quality assurance, documented corrective-action and complaint-handling procedures, and approximately six years of export experience with 31%–40% of sales from exports. It also states membership in the China Valve Industry Association and qualification as a National Power System supplier. However, it reports no valid manufacturing-capacity contract with related subcontractors, no inventory, overseas warehouse, overseas showroom, overseas agents or branches, or offline trade-show participation. Material traceability is absent, and the supplied financial records show zero values, limiting confidence in financial credibility. Customer-specific cases are not provided.
Supplier typeThe supplier describes itself as an ODM/OEM partner for power generation, water treatment, petrochemical, and industrial automation applications. Its stated business scope also includes waste processing, construction and metal materials, office equipment, surveillance, networking, and information-security equipment, indicating a broad and potentially diversified profile.
CertificationsThe supplier explicitly states that it is a member of the China Valve Industry Association and a qualified supplier for the National Power System. These are stated industry affiliations and qualification claims, although no certificate numbers, validity dates, or supporting documents are provided.
Financial creditThe supplied financial information reports zero operating revenue, costs, profits, cash receipts, cash inflows, cash outflows, and current ratio for the stated periods. These records do not establish financial strength and create a material basis for concern, although the data alone does not explain whether the values reflect inactive operations, reporting limitations, or another issue.
R&D capabilityThe supplier reports 3D software design services and states that it introduced new products during the past year. This provides explicit evidence of active product-development capability.
Customization capabilityThe supplier explicitly offers customization from samples and designs, full and minor customization, flexible customization, and 3D software design services. Its ODM/OEM positioning further supports the conclusion that it is structured to handle customer-specific requirements.
