HT PIPE employs advanced welding techniques to ensure structural integrity and longevity:
1. Welding Methods:
• TIG/MIG/SAW: Used for root passes and filling layers, ensuring precision and minimal heat distortion.
• Plasma Welding: Applied for high-purity applications, such as pharmaceutical or food-grade pipelines.
2. Critical Welding Practices:
• Pre-Weld Preparation:
Beveling: Mechanical or plasma cutting for clean edges, followed by removal of contaminants (oil, rust) within 20mm of the weld zone.
Anti-spatter measures: Use of anti-spatter agents or protective coatings on stainless steel surfaces to prevent contamination.
• Welding environment control:
Maintain argon shielding during TIG welding to avoid oxidation.
Avoid welding in humid or high-wind conditions to prevent porosity.
• Post-Weld Treatment:
Pickling and passivation: Removes oxide layers and enhances corrosion resistance.
Solution Annealing: For stress relief in thick-walled components.
HT PIPE adheres to stringent quality protocols to meet ISO, ASTM, AISI standards:
1. Non-destructive testing (NDT): Ultrasonic testing (UT) and X-ray testing, Penetrant Testing (PT)
2. Dimensional Accuracy
3. Other Third Party Inspection Agencies
