LRUT Screening for Critical Pipeline Zones Including Supports, Clamps, Low Points, and Injection Areas
Introduction Why Critical Zones Require Specialized Screening
Certain areas of a pipeline are statistically more prone to corrosion and structural degradation. These include support locations, clamps, low points, injection points, and areas of geometry change.
These zones often experience:
➤ Moisture accumulation
➤ Mechanical stress concentration
➤ Coating damage
➤ Crevice corrosion
➤ Chemical concentration
➤ Flow-induced erosion
Because of this, these areas represent higher integrity risk.
NDT AND PWHT SOLUTIONS PVT LTD provides specialized LRUT / Guided Wave Ultrasonic Testing (GWUT) services focused specifically on critical pipeline zones, enabling early detection and risk prioritization.
What Are Critical Pipeline Zones?
🔹 Supports & Saddles
Corrosion due to moisture entrapment and coating breakdown.
🔹 Clamps & Shoe Locations
Crevice corrosion under clamps and contact points.
🔹 Low Points
Water and sediment accumulation zones leading to internal and external corrosion.
🔹 Injection Points
Localized turbulence and chemical concentration risks.
🔹 Dead Legs
Stagnant fluid zones promoting corrosion.
🔹 Geometry Changes
Reducers, tees, and elbows where flow characteristics vary.
How LRUT Enhances Critical Zone Screening
Guided wave inspection allows:
➤ Screening across support-dense sections
➤ Detection of wall-loss near attachment points
➤ Evaluation of low-point regions
➤ Assessment of corrosion-prone configurations
➤ Screening beyond physically visible areas
LRUT is especially valuable in congested pipe racks where direct UT access is difficult.
