Welcome to Leader in NDT & Inspection Service since 2007
Global Certificate: ISO 9001:2015
BISCO offers Liquid Penetrant testing of surface discontinuities to inspect materials & welds of pipes, pressure vessels & other process equipment’s on the construction projects & process plants.
+ High sensitivity to small surface discontinuities
+ Easy inspection of parts with complex shapes
+ Quick and inexpensive inspection of large areas and large volumes of parts/materials
+ Few material limitations (metallic and nonmetallic, magnetic and nonmagnetic, and conductive and nonconductive can all be inspected)
+ A visual representation of the flaw are indicated directly on the part surface
+ Aerosol spray cans make the process portable, convenient, and inexpensive
+ Indications can reveal relative size, shape, and depth of the flaw
+ It is easy and requires minimal amount of training
+ Only surface breaking defects can be detected.
+ Only materials with a relatively nonporous surface can be inspected.
+ Precleaning is critical since contaminants can mask defects.
+ Metal smearing from machining, grinding, and grit or vapor blasting must be removed prior to LPI.
+ The inspector must have direct access to the surface being inspected.
+ Surface finish and roughness can affect inspection sensitivity.
+ Multiple process operations must be performed and controlled.
+ Post cleaning of acceptable parts or materials is required.
+ Chemical handling and proper disposal is required.
