Fatal accidents occur yearly because of faulty pressure vessels. This is the number one reason why quality control for pressure vessels is so essential.
InTouch is one of the leading inspection companies focused on inspecting such vessels in China. Some of the things we take into account in our inspection and verification process include:
Visual Inspection
A Visual inspection includes various methods which require tools and equipment of better rendering of judgment. Pictures shall be taken for as part of documentation.
- Inspect that the pressure vessel does not contain any surface damage and distortion
- Inspect to ensure information such as date of production, the manufacturers name, the serial number of the pressure vessel and the specifications in which the pressure vessel complies are located on the pressure vessel.
- Liquid Penetrant Test is performed to test the pressure vessel for any leaks in the materials by using dye to display cracks and material defects.
Functional Inspection
- Hydrostatic pressure test is performed to detect if the pressure vessel contains any cracks, flaws or leaks.
- Magnetic Particle inspection test is performed to detect cracking from functional stress with pressures running at 30000 psi.
Materials Inspection
- Thickness measurements test is performed using ultrasonics to test the pressure vessel to ensure the thickness complies to standard.
- Radiographic Inspection tests are performed on the welds in the pressure vessel to ensure the products contains no defects and cracks.
Acoustic Inspection
- Acoustic Emission Tests are performed to detect crack growth in pressure vessels.
InTouch constantly upgrades its pressure vessel inspection and quality control protocols by keeping an eye on the latest and most relevant international standards concerning the pressure vessel industry. A few of these standards include:
AS 1210
The AS 1210 contains inspection protocols and certification information for pressure vessels constructed by casting, welding and forging. This standard is required for safe and proper functioning of pressure vessels.
CSA B51
The CSA B51 is performed to regulate the size limitations of gauge pressures. The B51 is intented for all pressure vessels and boiler systems.
EN 286
The EN 286 contains safety specifications intended for pressure vessels that contain nitrogen or air at a gauge pressure greater than 0.5 bar but not greater than 30 bar. It is not intended for pressure vessels manufactured for nuclear use, ships, aircraft, and fire extinguishers.
PD 5500
The PD 5500 contains the inspection procedures and specifications for pressure vessels made out of carbon, austenitic steels and ferritic alloy, copper, nickel and aluminum.
ASME BPVC
The ASME BPVC standard is intended for pressure vessels used in locomotive, traction and portable service. The standard describes design, safety and manufacturing specifications and testing requirements.
ASME PVHO-1
The ASME PVHO-1 standard specifies testing, markings, and stamping design protocols for pressure vessels developed for human occupancy.
