Siphon Refractories Pvt. Ltd.

India hosts Siphon Refractories Pvt. Ltd., which currently lists 29 distinct product lines across refractory, mechanical and electrical categories. The catalogue includes fire‑clay and high‑alumina refractories (HS 6902.10), rolling‑mill spare parts made from alloy steel, high‑chromium cast iron or forged steel (HS 8455.90), and mixed‑material electrical components such as copper, brass and aluminium assemblies (HS 8538.00). Additional entries cover silica‑sand based ramming mass (HS 6903.20), high‑alumina calcium aluminate castables (HS 6903.20), precast concrete well blocks (HS 6810.99) and a 90 k mortar blend (HS 3824.50). Metal‑based items such as dummy bar bolts (HS 7318.15) and lancing pipes (HS 7304.51) are also listed, together with ferro‑silicon, silico‑manganese and sodium silicate chemicals. The product set further includes a variety of nozzle and tundish accessories, plumbing fittings and assorted pipe, flange and hose components (HS 7307.23).

The supplier’s catalogue groups products by function and material. Refractory items comprise fire‑clay bricks, high‑alumina castables, ramming mass and specialised tundish boards, all of which are typically formulated to meet ASTM C618 or ISO 11584 standards for chemical resistance and thermal shock. Rolling‑mill spares and mechanical seals are offered in alloy‑steel grades such as ASTM A335 (high‑temperature ferritic) or ASTM A182 (chromium‑molybdenum) and are machined to dimensional tolerances of ±0.02 mm for critical shafts. Electrical components follow IEC 60204‑1 safety requirements and are often supplied with copper conductors of 1 mm² to 35 mm² cross‑section. Chemical products such as silico‑manganese and ferro‑silicon are graded by silicon and manganese content, with typical purity levels of 60‑75 % Mn and 14‑30 % Si for SiMn. Standard packaging includes 20‑ft containers for bulk refractory powders, 40‑ft containers for rolled steel parts, and 25 kg drums for chemicals, each sealed to prevent moisture ingress.
