Preventive maintenance efforts have been underway for some time to monitor structural integrity of pipe and equipment in the process industries. In its most basic form a visual inspection is made to assess surface corrosion. Increasingly, electronic testing (ultrasonic, infrared, vibration, etc.) is employed, in addition to visual inspection, which typically requires that a transducer probe make contact with the pipe or equipment surface. Design Specs & Pricing

The use of inspection plugs on insulated pipe and equipment reduces both the expense of periodic testing access and the risk of increased corrosion.

Material Specifications:

The NDT Inspection Plug consists of two parts:

1. The Sleeve is made of 50 durometer EPDM as follows:
   • Ethylene Propylene Rubber
   • Chemical Resistance: Excellent
   • Ozone, Water/Steam Resistance: Excellent
   • Permanent Set Resistance: Excellent
   • Temperature Range: -65F (-54 C) to +300F (+149 C) for Continuous Operation
   • Tensile Strength: 1400 PSI
   • Elongation: 300%
   • ASTM D2000 2BA 510 A₁₄B₁₃C₁₂F₁₇
2. The Plug Cap comes standard in dead soft aluminum #5052, or optional (304) Stainless Steel

• NDT Inspection Plugs consists of an EPDM Sleeve and Aluminum Cap – standard
• NDT 2 Inspection Plugs also include a handle with stainless steel lanyard
• Sizes for the NDT and NDT 2 Plugs are 1.5”, 2.5”, 3.0” and 5.0”

US Federal guidelines recommend testing be conducted periodically, in the same locations, to monitor integrity and degradation rates.
