Tolerances and Inspection
Outer Diameter: ±0.3mm to ±2mm
Wall Thickness: ±5% to ±10%
Outer Diameter Measurement: Measure the pipe’s outer diameter using calipers or an outer diameter gauge (e.g., laser measuring instrument) to ensure compliance with standard tolerance ranges.
Wall Thickness Measurement: Measure wall thickness using an ultrasonic thickness gauge or mechanical calipers to verify compliance with design requirements.
Straightness and Bend Inspection: Ensure pipe straightness to prevent issues caused by bending or deformation during installation.
X-ray or Ultrasonic Inspection: Examine internal weld integrity to confirm absence of cracks or defects.
Visual Inspection: Conduct visual checks on welded joints to ensure neat welds without obvious flaws.
Pressure Testing: Perform pressure tests to evaluate the pipe’s ability to withstand internal pressure, ensuring operational safety under high-pressure conditions.
Hardness Testing: Conduct hardness tests on pipes to ensure material hardness meets specifications, particularly for high-temperature applications where sufficient strength is required.
Electrical Conductivity Testing: Evaluate the electrical conductivity of metal pipes to ensure reliable conductivity within electrical systems, suitable for power transmission conduits.
It can be connected via threaded, flanged, or butt joints. The pipe is flexible, facilitating installation in complex environments.
Made of galvanized or stainless steel, it effectively prevents rust and is suitable for various harsh environments.
Threaded Connection: Joins pipes using threaded fittings, suitable for smaller diameters.
Welded Connection: Used for larger diameters, providing superior joint strength.
Clamp Connection: Secures pipes with metal clamps or fasteners, ideal for quick installations.
Flange Connection: Connects pipes via flanges and bolts, commonly used in high-pressure applications.
Ensure pipes are not excessively bent during installation and maintain proper sealing integrity.
