Products Description
Our Advantages
1. Corrosion Resistance
- TORICH 316 Large Diameter Stainless Steel Pipe is made from high-quality stainless steel materials such as 316/316L, and the pipes undergo bright annealing treatment. The passivated chromium oxide layer on the surface prevents corrosion from corrosive substances.
- The pipes are tested using a spectrometer and intergranular corrosion tests to ensure long-term durability in wastewater treatment and chemical fluid transportation.
2. Precise Dimensions
- Our welded pipes are manufactured using a cold drawing process after welding, resulting in a smooth surface and uniform wall thickness, ensuring excellent concentricity and straightness for smooth installation with flange connections.
- TORICH pipes undergo systematic dimensional inspection during and after production to ensure proper fit with flanges, fittings, and welded joints.
3. Excellent Mechanical Properties
- TORICH 316 Large Diameter Stainless Steel Pipe improves yield strength and tensile strength through a precise cold drawing process, and bright annealing restores ductility and toughness, allowing them to withstand fluid pressure, thermal expansion, and mechanical stress.
- The pipes undergo rigorous mechanical performance testing to ensure high fatigue and vibration resistance, making them suitable for continuous flow wastewater systems.
4. Large Diameter Capability
- TORICH offers customized sizing services with outer diameters up to 1000mm, supporting high flow rates and reducing pressure loss in wastewater treatment pipelines.
- TORICH has specialized cold drawing equipment designed for large outer diameters and thick-walled sections, ensuring that the outer diameter and wall thickness of the pipes meet standard specifications.
5. Welding Quality
- Our pipes are produced using advanced automatic welding processes, ensuring consistent weld penetration. The cold drawing process eliminates typical weld defects such as uneven thickness and weak areas.
- Our pipes support TIG welding, MIG welding, and orbital welding, facilitating efficient on-site installation.
