Manufacturing Processes
Raw Material Sourcing
Raw materials for plastic tubes are sourced from a global network of polymer suppliers, with a preference for suppliers that adhere to environmental and quality standards. Dinesh Tube maintains long-term agreements with key resin manufacturers to secure stable pricing and ensure consistent material quality. For steel tubes, the company procures carbon steel billets from domestic steel mills, supplemented by alloy steel imports when required for specialty applications.
Extrusion and Molding
The extrusion process for PVC and HDPE tubes involves melting the polymer resin and forcing it through a precision-engineered die. The extruded tube is then cooled in a controlled environment to achieve the desired wall thickness and surface finish. The company uses multi-cavity extrusion units, allowing simultaneous production of multiple tube diameters and reducing energy consumption per unit.
For HDPE, the extrusion line incorporates a twin-screw extruder that enhances polymer mixing and homogenization. This ensures consistent mechanical properties across the product batch. The extrusion process is monitored using real-time sensors that track temperature, pressure, and flow rate, thereby enabling rapid detection of anomalies.
Steel Tube Production
Steel tubes are produced using a combination of seamless and welded manufacturing techniques. The seamless production line involves heating a steel billet, drawing it through a die, and subsequently extruding the tube without any welds. This process yields tubes with superior strength and corrosion resistance, ideal for high-pressure applications.
The welded line utilizes flat steel plates that are rolled, cut into circular sections, and welded along the seam. The process is followed by a heat treatment stage that reduces residual stresses and improves mechanical properties. Both production lines are equipped with automated inspection stations that measure wall thickness, diameter, and surface integrity.
Quality Control and Testing
Quality control at Dinesh Tube is governed by a comprehensive set of protocols aligned with ISO 9001:2015. Every batch of tubes undergoes dimensional verification, tensile testing, burst pressure assessment, and chemical composition analysis.
