Square Pouring Pipe

Square Pouring Pipe is a high-performance refractory component designed to channel molten metal from ladle to mould cavity in a controlled and stable manner. Its square geometry allows better alignment within rectangular gating systems, ensuring balanced metal distribution and improved flow control during casting operations.

The structured shape helps reduce turbulence, minimize air aspiration, and prevent slag or impurity entry into the mould cavity. By maintaining steady metal velocity and pressure, the Square Pouring Pipe supports laminar flow, resulting in improved casting surface finish and reduced internal defects such as blowholes and oxide inclusions.

Its design also helps protect the mould and sprue system from erosion caused by direct molten metal impact. This enhances mould life, improves dimensional stability, and contributes to consistent casting quality. The square configuration is particularly suitable for mould systems requiring structured metal entry and precise flow direction control.

Manufactured from silica-based refractory material with minimum 70% of silica content, the Square Pouring Pipe offers reliable thermal resistance during high-temperature pouring operations. Controlled density and adequate transverse strength ensure safe handling and structural integrity under foundry conditions.
