JS Fittings supplies industrial flanges manufactured to ASME B16.5, ASME B16.47, ASME B16.48, EN 1092, GOST 12820, GOST 12821, GOST 33259, and SABS/SANS 1123 standards. These flanges are available in weld neck, slip-on, socket weld, threaded, and blind configurations, with material options including ASTM A105 carbon steel, stainless steel 304 and 316, and alloy steel. Dimensions and pressure ratings align precisely with the referenced standards, ensuring compatibility with global pipeline systems.
The flanges are forged or cast depending on size and class, with carbon steel grades meeting ASTM A105 tensile and impact requirements. Stainless steel variants use 304 and 316 with certified chemical composition and mechanical properties. Surface finish typically follows ANSI B16.5 Class 150 to 2500 roughness tolerances. These materials are standard in high-pressure environments where corrosion resistance and structural integrity are critical, such as offshore platforms and refinery units.
These flanges are purchased by engineering firms, EPC contractors, and maintenance teams in oil and gas, petrochemical, water treatment, and power generation industries. Packaging is done in wooden crates with corrosion-inhibiting paper, suitable for containerized ocean freight. Export orders require material test reports (MTRs) and third-party inspection certificates. Lead times vary by volume and custom sizing, and incoterms are typically FOB Cangzhou or CIF destination port.

JS Fittings operates from Wuliyao Industry Zone in Cangzhou, Hebei Province, China, a known hub for forged and cast pipe components. The company identifies as a direct manufacturer with production capacity focused on flanges and fittings for export markets. Its profile does not state factory size, workforce count, or annual output, nor does it list client names or certifications such as ISO 9001. The listing confirms compliance with international standards but provides no evidence of third-party audit results.
The supplier's response rate is recorded as 0.00% and average response time as 0 hours, indicating no verified buyer communication history on the platform. Trust tier is classified as harbor, suggesting basic verification of business registration but no additional financial or operational validation. Buyers should treat this as a manufacturer with documented product compliance but unverified service responsiveness.
We supply a comprehensive range of industrial flanges manufactured to international standards including ASME B16.5, ASME B16.47, ASME B16.48, EN 1092, GOST 12820, GOST 12821, GOST 33259, and SABS/SANS 1123. Available in weld neck, slip-on, socket weld, threaded, and blind designs in carbon steel and stainless steel grades. Our flanges serve oil and gas pipelines, petrochemical plants, water treatment, and power generation applications. As a direct factory supplier, we offer competitive pricing for bulk export orders with full material test reports and third-party inspection support.

Before placing an order, verify the material grade with certified MTRs for each batch. Confirm that flange dimensions match the exact standard referenced in your design (e.g., ASME B16.5 vs GOST 12820). Request proof of heat treatment for carbon steel if used in low-temperature environments. Do not accept flanges without traceable material certification, as substitutions are common in unverified supply chains.
Confirm incoterms with the supplier - FOB Cangzhou is typical, but CIF or DAP may be negotiated. Lead time for standard sizes is 20 to 35 days; custom sizes may extend to 60 days. Payment terms are usually 30% advance, 70% against shipping documents. Ensure packaging meets container loading standards to prevent damage during ocean transit. Request a pre-shipment inspection report if the shipment value exceeds $50,000.
Perform dimensional checks using calibrated calipers and thread gauges upon receipt. Verify surface finish with a roughness tester. Check for cracks or laminations using magnetic particle inspection if the flanges are used in high-pressure systems. Retain MTRs and inspection certificates for compliance audits. For stainless steel flanges, confirm no iron contamination was introduced during handling, as this can cause rust spots and compromise corrosion resistance.
