Buy & Import Cast Iron Pipe Fitting from Cangzhou Doushan Machinery Manufacture Co., Ltd. - Wholesale Supply

Cast iron pipe fittings from Cangzhou Doushan are manufactured in ductile cast iron GGG50 or grey cast iron FGS500-7, conforming to ISO 2531, EN 545, EN 598, and GBT 13295 standards. These fittings include elbows, tees, reducers, and flanged adaptors, designed for pressure ratings up to 16 bar. The material composition ensures structural integrity under high hydraulic loads, making them suitable for municipal water distribution and underground sewer networks.

Ductile iron GGG50 offers higher tensile strength and elongation compared to grey iron FGS500-7, making it preferred for high-pressure applications. Grey iron remains common in low-pressure drainage systems due to its vibration-damping properties. Surface finishes are typically bitumen-coated or epoxy-painted for corrosion resistance, with internal bore tolerances held to ±0.5 mm. Packaging is in wooden cases with plastic layering, or as specified by the buyer.

These fittings are sourced primarily by civil contractors, municipal utilities, and infrastructure developers in regions with expanding water and sanitation networks. Buyers typically order in full container loads, with minimum order quantities negotiated per project. Lead times average 30 to 45 days after deposit. Incoterms offered include FOB Tianjin or CIF, with third-party inspections by SGS or BV accepted. Sample requests are available at buyer’s freight cost.

Frequently Asked Questions About Cast Iron Pipe Fitting from Cangzhou Doushan Machinery Manufacture Co., Ltd.
GGG50 ductile iron has a minimum tensile strength of 500 MPa and elongation of at least 7%, as defined by ISO 1083. This ensures resistance to brittle fracture under ground stress, critical for buried pipelines. Buyers should request a mill test report to verify batch-specific values.

Sourcing Cast Iron Pipe Fitting from Cangzhou Doushan Machinery Manufacture Co., Ltd. - China Import Guide

Before placing an order, verify the material grade (GGG50 vs FGS500-7), pressure class (K7, K9, etc.), and coating type. Request a copy of the latest mill test certificate and inspection report from SGS or BV. Confirm that the batch number on the certificate matches the shipment label. Do not accept fittings without traceable documentation, especially for potable water projects.

Lead time is typically 30 to 45 days after deposit, but this can vary with order volume and seasonal demand. Confirm Incoterms: FOB Tianjin is standard, but CIF may be offered. Payment terms are usually 30% advance via TT, balance against copy of B/L. Request a packing list and container loading photos before final payment. Always clarify whether samples are available and who covers freight.

Upon arrival, inspect for surface cracks, uneven coatings, or dimensional mismatches. Use a caliper to check socket and spigot diameters against ISO 2531 tables. Perform a visual check for internal debris or casting flash. Retain a sample from each batch for third-party lab testing if required. Ensure all documents - certificate of origin, compliance, and inspection - are provided in English and match the order specification.
