DN1800 Welded Dismantling Expansion Joint
The DN1800 Welded Dismantling Expansion Joint is supplied by Beijing Zhonghaiwei Environment Engineering Co. Ltd. in China. It is a heavy‑duty pipe fitting with a nominal diameter of DN1800 designed for large‑diameter pipeline systems. The joint body is fabricated from carbon steel or ductile iron and incorporates an echelon‑ring rubber seal. Manufacture is achieved through welding or metal casting, and the joint is operated by a gland and bolt mechanism to allow axial movement.
The rubber seal deforms elastically under pressure to provide a static seal between the joint body and the expansion pipe wall. High‑strength antifouling paint coats the exterior, while the bolts are made from high‑strength carbon steel or stainless steel. In the industry such joints are typically supplied to G/B standard and are comparable to other heavy‑duty expansion joints used in water supply and municipal infrastructure. Typical specifications include a pressure rating up to 1.6 MPa and an operating temperature range of - 20 °C to 120 °C.
Applications include connection of pumps, valves and pipe sections in power, metallurgy, drainage and sewage projects. Importers such as utility contractors, municipal engineering firms and industrial plant builders commonly source this item. As the listing does not disclose MOQ, lead time or payment terms, buyers should confirm those details directly with Beijing Zhonghaiwei before placing an order.

Sourcing DN1800 Welded Dismantling Expansion Joint from Beijing Zhonghaiwei Environment Engineering Co. Ltd. - China Import Guide
Before placing an order, importers should confirm the exact material grade, seal type, coating system and compliance with G/B standard. Request a material test report and a seal performance certificate to ensure the joint meets the required pressure and temperature specifications. Verification of the supplier's quality management procedures is also advisable.
Logistics terms such as Incoterms, estimated lead time and preferred payment method are not disclosed in the listing. Buyers need to ask Beijing Zhonghaiwei for the shipping mode, whether FOB, CIF or EXW applies, and for any freight forwarder recommendations. Clarifying payment milestones, such as a letter of credit or advance payment, helps mitigate financial risk.
For quality assurance, arrange a third‑party inspection at the factory or before loading to verify dimensions, coating thickness and bolt material. Request mill test reports, rubber seal hardness data and any applicable conformity certificates. Maintaining a complete documentation package, including packing list, certificate of origin and inspection report, will smooth customs clearance and project acceptance.
