Detailed Manufacturing Process of Dust Cover Tube

Manufacturing Workflow:
Raw Material Selection (316L SS, Alloy steel, PVC) → Cutting & Pre-processing → Forming (CNC Bending/Rotary Press) → Welding (TIG/MIG/Seamless Integration) → Heat Treatment (for alloy grades) → Precision Machining (CNC turning/milling for tolerance & finish) → Surface Treatment (Passivation, Powder Coating, Anti-corrosion spray) → Inspection & Quality Control (in line with ISO 9001, ANSI B16.9 standards) → Packaging & Delivery

Quality Checkpoints: Raw material spectrometry, Dimensional accuracy (
Certifications: ISO 9001:2015, EU RoHS, CE Marking, ANSI conformance.

CBI’s advanced Dust Cover Tube line achieves a 0.02mm CNC machining tolerance and includes 100% non-destructive ultrasonic testing, ensuring reliability in both high-vibration and corrosive installations. Product batches undergo random sampling per ISO 2859-1:2010 for quality assurance.

FAQ: Dust Cover Tube Technical Insights

1. What material grades are most recommended for Dust Cover Tube in corrosive environments?: For aggressive chemical or marine settings, 316L stainless steel is optimal due to its Mo-enriched composition, resisting pitting and crevice corrosion. Alloy steels or PVC-U are also viable where cost or specific chemical compatibility is prioritized.
2. What is the standard wall thickness range for industrial Dust Cover Tube?: Typically, wall thickness ranges from 1.6mm to 12mm, selected based on pressure class and exposure to physical/mechanical loads as per ANSI B36.10M and project specific engineering codes.
3. How does CNC processing benefit Dust Cover Tube manufacturing?: Computer Numerical Control (CNC) ensures sub-millimeter tolerance (
4. Which global standards must Dust Cover Tube comply with?: Compliance is expected with ISO 9001 (quality systems), ISO 9227 (corrosion testing), ANSI B16.9/B36.10M (dimensional), and CE directives for European projects.
5. How are Dust Cover Tube seals evaluated for ingress and life expectancy?: Seal design undergoes ingress protection (IP55-IP68) per IEC 60529, pressure cycle tests, and accelerated aging, supporting >10-year operational life.
6. What installation standards are followed for Dust Cover Tube?: Industry norms reference ASME B31.3/31.4/31.8 (piping system installation), and detailed installation manuals with precise torque, orientation, and support instructions.
