HOW TO INSPECT GRP LAMINATES?

Since plastic materials are often used for storing and processing corrosive stuff like acids, the consequences of a failure can be devastating. GRP pipe manufacturers would like to share details on non destructive testing of GRP laminates through this article. How to inspect GRP laminates and how NDT tool helps in the job is explained well in this post.

Non destructive testing or NDT tool is essential for inspecting GRP pipes and tanks. Earlier, NDT methods for field use have not been completely intended for adequate precision. Today, many modern facilities are running procedures for several testing methods of GRP laminates. It includes  

Radiographic testing Ultrasonic testing Visual testing

Digital radiography It is done with a portable digital imaging unit. The results are processed instantly and evaluated in digital computer. The equipment is user-friendly and small-scale.

Ultrasonic testing Ultrasonic testing is used for detecting delamination and corrosion. The structure of GRP material can make the use of ultrasound complex.

Visual inspection To standardize and enhance the process of visual inspection, professionals take help of tool to detect the most common defects. This allows experts to distinguish manufacturing defects from others that have been appeared during operations.

With the help of these three NDT methods, it is possible for the manufacturers to comply with available regulations, even if the component is made of GRP material.

The inspection of welds and joints is also important for ensuring safety and quality of newly commissioned plants prior taking the ownership from the owner or contractor of the site. NDT plays critical role in the inspection.

Advantages of NDT of Glass fibre reinforced laminates      

You meet requirements of authorities You ensure safety and quality of newly commissioned plants prior acquiring the ownership from contractor of site.

You prevent devastating failures by regulating the storing and processing risks related to corrosive liquids.

You get reliable detection of defects You plan timely repairs and maintenance You lower the failure risks by determining the worn out GRP pipes You get help from NDT techniques to achieve precise control of the material

GRP pipes are applied in following industries:       

Automotive Aerospace Chemical Water and wastewater engineering Wind turbines Electrical industries Sports equipment

GRP pipe manufacturers have shared their best knowledge about NDT methods used for testing GRP laminates. The three techniques – radiography, ultrasonic and visual inspection are widely popular and are used by modern facilities to test GRP laminates. If you want to explore more about this topic, you may do research online.
