The Nipple Graphite Electrode Nipple supplied by Linzhang County Hengqiang Carbon Co., Ltd is a precision‑engineered conical connector used to join carbon or graphite electrodes in electric arc furnaces. It is manufactured from artificial pitch‑based graphite with a carbon purity of at least 99.9 %. The catalogue offers four standard types - 3TPI, 3TPIL, 4TPI and 4TPIL - each matching specific electrode diameters. Dimensions are listed for diameters from 75 mm up to 600 mm, with joint pitch, thread diameter and length detailed for each size.
The high carbon content gives the nipple low electrical resistivity and excellent thermal shock resistance, allowing reliable operation above 3000 °C. The tapered threads are designed to provide high flexural strength while simplifying assembly and disassembly in harsh furnace environments. Typical industry practice specifies a joint pitch tolerance of ±0.1 mm and a thread diameter tolerance of ±0.2 mm. Standard packaging bundles the nipples in wooden crates to protect the conical surfaces during bulk transport.
Steel makers and secondary‑steel producers are the primary buyers, integrating these nipples into continuous casting lines and reheating furnaces. Trade terms such as MOQ, Incoterms and payment conditions are negotiated directly with the supplier and are not disclosed publicly. Prospective importers should request the latest material test report and confirm any custom‑size requirements before placing an order.

The supplier states that its production follows international standards, delivering components with high strength, temperature resistance and corrosion resistance. While the listing does not provide specific certifications, buyers can request material test certificates and quality audit reports as part of the procurement process. The company’s catalogue highlights low resistivity and strong anti‑oxidation performance as key product attributes.
Graphite electrode nipples are precision-engineered conical connectors used to join carbon/graphite electrodes in electric arc furnaces during steelmaking. Manufactured from high-purity artificial graphite, typically exceeding 99.9% carbon content, these nipples feature tapered threads engineered to withstand extreme temperatures above 3000C and high electrical conductivity demands. Widely sourced from major producers in China and India for export to steel mills globally, they are critical consumable components in secondary steel production operations. Pricing varies by grade (HP/UHP) and diameter specifications, with bulk procurement contracts common in international trade.

Before placing an order, importers should obtain the material test certificate confirming the artificial graphite grade and carbon content. Verify the dimensional drawing for the selected type (3TPI, 3TPIL, 4TPI or 4TPIL) against your electrode specifications, and request a sample if possible. It is also prudent to check the supplier’s export licence and any applicable Chinese certification for graphite components.
Logistical arrangements typically involve sea freight from ports in Hebei province, with Incoterms such as FOB Tianjin or CIF Shanghai commonly negotiated. Lead times are not published, so ask the supplier for an estimated production and shipping schedule. Payment terms are usually a letter of credit at sight or a 30 % deposit with balance against documents; confirm the exact terms before contract signing.
During import, arrange a third‑party inspection to verify the carbon purity, dimensional tolerances and surface condition of the nipples. Request the supplier’s factory audit report and any ISO or industry standard compliance documents. Upon arrival, retain the test certificates and packaging inspection report as part of your quality assurance records.
