- Description
- Cast Iron Inserts PN-002-004-590 & PN-002-004-591 The cast elements are manufactured from Spheroidal Graphite Iron (SGI) in accordance with EN 1563. Spheroidal Graphite Cast Irons, grade EN-GJS-450-10. Typical Chemical Composition (controlled at supplier/foundry level): - Carbon (C): 3.4 – 3.9 % Silicon (Si): 2.2 – 2.8 % Manganese (Mn): ≤ 0.30 % Phosphorus (P): ≤ 0.05 % Sulphur (S): ≤ 0.02 % Magnesium (Mg): 0.03 – 0.06 % (residual, to ensure spheroidal graphite formation) Iron (Fe): Balance Minor alloying elements such as Copper (Cu), Nickel (Ni), or Molybdenum (Mo) may be added in controlled and limited quantities when required to achieve the specified mechanical properties. Minimum Tensile Strength: ≥ 450 MPa, and Minimum Elongation: ≥ 10 %. The cast elements are produced using a Green Sand Casting Process with an automated High Pressure Moulding Line (HPML). Raw Material Charging and Melting Approved base iron, steel scrap, and internal returns are charged into an induction furnace. The molten iron is treated with magnesium-based alloys to convert graphite into a spheroidal (nodular) form. Green Sand (HPML) Moulds are produced on an automated high-pressure moulding line using green sand composed of silica sand, bentonite clay, water, and additives. HPML ensures high dimensional accuracy, repeatability, and stable mould quality. Molten SGI is poured into the prepared moulds under controlled temperature and pouring conditions. Castings are allowed to solidify and cool under controlled conditions to minimize defects. After cooling castings are removed from the moulds. Gates, risers, and excess material are removed through fettling operations such as cutting and grinding. For use in the offshore energy industry for pipeline protection. Insert is over moulded within a polymer product to provide asset protection, impact resistance and stabilization. Usually packed in crates.

- Justification
- Classification has been determined in accordance with the following: For the purposes of determining the commodity codes within which goods most appropriately fall, Reg 3 (1) of The Customs Tariff (Establishment) (EU Exit) Regulations 2020 sets out that the rules of interpretation contained in the following have effect – a. Part Two (Goods Classification Table Rules of Interpretation) of the Tariff of the United Kingdom (Reg 3(1)(a); and b. Notes to a section or chapter of the Goods Classification Table (Reg 3(1)(b)) GIR 1 has been used to classify this product by the terms of heading 7325 - Other cast articles of iron or steel. GIR 5(b) has been used to identify the type of packaging. GIR 6 - has been used to classify the goods to subheading level 732599 - Other. 8 Digit Code 73259910 - Of cast iron. 10 Digit Code - 7325991090 - Other. Also classified in accordance with: Harmonised System Explanatory Notes (HSENs) to 7325
