The elliptical head offered by Dingjin General Machinery Co., Ltd. is a pressure‑vessel component produced in Dalian, China. The product range covers diameters from Φ325 mm to Φ10000 mm with thicknesses between 8 mm and 50 mm using integral spinning technology, while integral stamping can achieve a maximum size of Φ6000 × 400 mm. The company also states that heads with a thickness up to 300 mm are possible when multiple petals are employed.
Manufacturing relies on German‑made spinning units (models DF10050, DF2220 and MD21/5030) and a suite of hydraulic presses ranging from 1000 to 16000 tons, allowing a wide variety of shapes and specifications. Typical industry practice for such heads uses carbon‑steel grades such as ASTM A516, designed according to ASME Section VIII standards, and includes heat‑treatment in seven furnace sets. The facility spans 74 000 square metres and is equipped with 28 cranes capable of lifting up to 100 tons, supporting large‑scale production.
Elliptical heads are commonly used in oil‑and‑gas, petrochemical and power‑generation plants, where EPC contractors and refinery engineers specify them for high‑pressure service. Buyers should request detailed drawings, material test reports and confirm the applicable design code before placing an order. Trade terms, minimum order quantities and incoterms are not disclosed in the listing and must be agreed directly with the supplier.

Before placing an order, verify Dingjin's corporate registration, factory address and the existence of the listed equipment such as the German spinning units and high‑capacity hydraulic presses. Request recent mill test certificates, material grade confirmation and any third‑party inspection reports that demonstrate compliance with ASME or equivalent standards. Confirm that the supplier can provide detailed engineering drawings matching your required dimensions and tolerances.
Logistics and trade terms are not disclosed in the product data, so importers should ask the supplier to specify lead times, preferred incoterms (for example FOB Dalian or CIF Shanghai) and acceptable payment methods. Because the response rate appears to be zero, establish a reliable point of contact and obtain written confirmation of shipping schedules and any freight forwarding arrangements before finalising the contract.
Quality assurance for elliptical heads typically involves dimensional inspection, non‑destructive testing and verification of heat‑treatment procedures. Importers should arrange for a third‑party inspection agency to conduct a pre‑shipment audit, request a full set of mill test certificates, welding procedure specifications and pressure‑test results. Ensuring these documents are provided will help meet downstream certification requirements and reduce the risk of non‑conformance.
