Buy & Import Double Socket Taper For Di Pipe from Qingdao Valtech Manufacturing Co., Ltd. - Wholesale Supply

The Double Socket Taper for DI Pipe supplied by Qingdao Valtech Manufacturing Co., Ltd. is a ductile‑iron fitting designed to join pipes of different diameters. It conforms to BS EN 545 and ISO 2531 standards and is offered in nominal sizes from DN100 to DN2600. Each unit receives a bitumen coating on both the interior and exterior surfaces to resist corrosion in water transmission systems. The product is listed with a minimum order of one piece and a twelve month warranty.

The fitting is cast from GGG 40/50 nodular cast iron, a grade that provides high tensile strength and good ductility for pressure‑bearing applications. Bitumen coating is a common protective finish for underground water infrastructure, extending service life by preventing moisture ingress. In the pipe‑fitting industry, gravity‑cast ductile‑iron tapers of this size range are typically supplied with a pressure rating of up to 16 MPa. Valtech also offers OEM, ODM and OBM services to adapt the taper geometry or coating thickness to project specifications.

These tapers are widely used in municipal water supply networks, irrigation schemes and industrial fluid transfer lines where reliable pressure resistance is required. International buyers usually arrange payment by Letter of Credit or Telegraphic Transfer and may request shipment in plywood cases or on pallets. The supplier’s trust tier is classified as harbor, indicating a verified business profile, while response metrics are currently unavailable. Prospective importers should confirm the required size, coating specification and delivery schedule before placing an order.

Frequently Asked Questions About Double Socket Taper For Di Pipe from Qingdao Valtech Manufacturing Co., Ltd.
The fitting is manufactured to comply with BS EN 545 and ISO 2531, both of which specify dimensional tolerances, material requirements and pressure‑class limits for ductile‑iron pipe fittings. Buyers should request the certification documents to verify conformance.

Sourcing Double Socket Taper For Di Pipe from Qingdao Valtech Manufacturing Co., Ltd. - China Import Guide

Before confirming a purchase, importers should request the latest BS EN 545 / ISO 2531 test certificates and a material analysis report confirming the GGG 40/50 grade. Verifying the bitumen coating thickness and ensuring the supplied size matches the project drawings will reduce the risk of mismatched fittings. It is also advisable to check the supplier’s harbour‑level verification status and request a recent factory audit report if available.

The typical shipping method is containerised freight with the fittings packed in plywood cases or on pallets, which fits standard 20‑ft or 40‑ft containers. While the listing mentions L/C or T/T as acceptable payment terms, buyers should agree on Incoterms such as FOB Qingdao or CIF destination port to define responsibility for freight and insurance. Lead‑time estimates are not disclosed, so request a production schedule and estimated dispatch date before finalising the order.

On receipt, purchasers should arrange third‑party inspection to verify dimensional tolerance, coating integrity and pressure‑test results against the supplied certificates. Retaining the original test reports, coating‑thickness logs and packing list will support customs clearance and future warranty claims. If any deviation is found, the twelve month warranty offered by the supplier can be invoked after notifying the manufacturer in writing.
