Inspect industry equipment


Inspection of Industrial Equipment 

Inspection of Pressure Vessels 

Inspection of Tanks, Boilers, Furnaces, and Towers


The inspection of tanks, the primary equipment used in industry, is one of the most important and sensitive types of inspection. It is divided into three main categories:  

1. Pre-construction inspection

2. Inspection during construction

3. Post-construction inspection  


Pre-construction and in-process inspection of pressure tanks are conducted by ASME SEC VIII standards or other national or internationally recognized standards. The inspection process includes the following steps:


- Reviewing documents and records, including approved drawings, welding procedure specifications (WPS), procedure qualification records (PQR), and welder qualification records (WPQ).  

- Inspection of raw materials and consumable parts  

- Dimensional inspection  

- Visual inspection of surfaces and edges 

- Visual inspection of welded joints 

- Radiographic or ultrasonic testing of welded joints according to standard requirements**  

- Supervision of hydrostatic testing

- Supervision of heat treatment operations, if necessary 


Fixed Tanks - Storage Tanks and CNG Tanks 


Fixed Storage Tanks  

Fixed storage tanks refer to aerial and ground tanks used for storing water, fuel, and industrial materials in refineries, power plants, petrochemical industries, and other industrial sites. In petrochemical industries, storage tanks are used to store gaseous liquids, chemicals, water, etc. These tanks operate at pressures below 15 PSI  


Inspection items include:

- Shell plate inspection for corrosion and deformation

- Inspection of circumferential and longitudinal weld joints for corrosion and cracking  

- Inspection of internal coatings (if applicable)  


Storage Tank Inspection  

Internal Inspection - Bottom Plate  

- Thickness measurement and calculation of remaining life of bottom plates and annular plates  

- Inspection of bottom plates and annular plates for corrosion and deformation 

- Inspection of welding joints for corrosion and cracking, especially annular plate-to-shell connections 

- Close inspection of internal coatings (if applicable)  

- Sample plate inspection, including removal of corroded sections 

- Inspection and supervision of vacuum testing  


Internal Inspection - Roof Structure

- Inspection of roof plates for corrosion and deformation 

- Inspection of structural roof members for corrosion and deformation 

- Inspection of weld joints in roof plates and structural members for corrosion and cracking 

- Inspection of internal coatings (if applicable)  


Inspection Methods for Storage Tanks  

CNG Tanks  

Inspection of Compressed Natural Gas (CNG) equipment** is conducted to monitor and ensure technical safety, preventing accidents and losses.  

- Supervision of pressure testing and complementary tests such as ultrasonic testing and immersion tests 

- Examination of corrosion on the tank body and internal surfaces
