Strict Material Control: The Foundation of TORICH Quality
To deliver high-quality stainless steel products, TORICH strictly adheres to a rigorous raw material selection process that starts from the very source - the billet.
High-Purity Billets from Trusted Steel Mills
We prioritize first-grade virgin stainless steel billets sourced from reputable large-scale steel mills. Unlike recycled or substandard alternatives, these billets feature:
- Precise and stable alloying element content (e.g., chromium, nickel, molybdenum)
- Extremely low impurity levels, such as: Carbon ≤ 0.08%, Sulfur ≤ 0.03%
Full-Process Traceability System
To ensure quality from start to finish, TORICH has implemented a comprehensive traceability system:
- Incoming Inspection: Each billet batch must be accompanied by a Material Test Certificate (MTC) from the steel mill.
- In-House Verification: Our laboratory performs spectral analysis and metallographic testing to double-check composition accuracy and internal structure.
- Batch Record Tracking: Detailed billet batch data is recorded and linked throughout the production process, enabling full traceability from raw material to finished product.
Sustainable and Compliant Materials
TORICH are committed to eco-conscious sourcing and sustainable manufacturing practices.Our materials comply with:
- RoHS and REACH directives
- ISO 9001:2015 for quality management
- ISO 14001:2015 for environmental responsibility
Advanced Equipment: Ensuring Quality Through Technology
At TORICH, we understand that advanced equipment is essential to producing high-quality stainless steel pipes. That's why we continuously invest in state-of-the-art production and testing systems, ensuring precision, efficiency, and consistency at every stage of manufacturing.
Comprehensive Seamless Stainless Steel Pipe Production Lines
Our factory boasts a complete suite of dedicated stainless steel pipe manufacturing lines:
- 22 Cold-Drawing Lines: Deliver precise dimensional control and smooth surface finishes, ideal for high-precision applications.
- 18 Cold-Rolling Mills: Achieve excellent dimensional accuracy and mechanical strength by enhancing the internal grain structure of the material.
- 6 Bright Annealing Furnaces: Ensure oxide-free internal and external surfaces, improve corrosion resistance, and stabilize mechanical properties.
Advanced In-House Testing & Inspection Equipment
Our quality control laboratories and inspection stations are fully equipped to perform 100% inspection throughout the production process, guaranteeing the reliability and performance of every pipe. Key testing equipment includes:
- Eddy Current Testing Machines: For non-destructive detection of surface and sub-surface defects.
- Ultrasonic Testing Systems: For detecting internal flaws and verifying wall thickness uniformity.
- Hydrostatic Pressure Testing Equipment: Ensures every pipe meets the required pressure resistance and is free from leakage.
- OES (Optical Emission Spectrometers): Accurately verify the chemical composition of both raw billets and finished products.
- Tensile and Hardness Testing Machines: Confirm that mechanical properties comply with customer requirements and international standards.
