Certifications

ASME - American Society of Mechanical Engineers
Custom Air Coolers currently holds the ASME U and UM stamps. Our products can be designed, constructed, and tested to meet the requirements of the applicable section of the ASME Boiler and Pressure Vessel Code.

CRN - Canadian Registration Number
Coils with working pressures over 15 psi that are installed in Canada must have a Canadian Registration Number (CRN) issued by the province where the coils will be installed. Custom Air Coolers obtains CRN numbers in accordance with the Canadian "Boiler" Pressure Vessel and Pressure Piping Code (B51).

NB - National Board
This American National Standard has been adopted by most states and cities, all Canadian provinces, and federal regulatory agencies. It is the only standard recognized worldwide for in-service inspection repairs and alterations of boilers and pressure vessels. The standard also serves as a permanent registration containing calculations and other pertinent information required for ASME certification.

API Standard 661: Air-Cooled Heat Exchangers for General Refinery Service
Custom Air Coolers can provide compliance with this International Standard, which provides requirements and recommendations for the design, materials, fabrication, inspection, testing and preparation for shipment of air-cooled heat exchangers for use in the petroleum and natural gas industries.

API614 flushing capability
API Standard 614: Lubrication, Shaft-Sealing, Control-Oil Systems and Auxiliaries for Petroleum, and Chemical and Gas Industry Services. Custom Air Coolers can provide in-house oil flushing meeting the intent of Paragraph 4.3.3.7.1 of API Standard 614 with our on-site oil flushing skid.

CE European Mark
Coils installed in Europe are required to be built in accordance with the Pressure Equipment Directive (PED). The PED dictates when a CE mark can and cannot be applied to a coil. Custom Air Coolers can build coils in accordance with the PED for Categories I, II, and III.

CWB

Canadian Welding Board
This is a structural steel welding certification for the country of Canada. The current certification is under standard W47.1-Division: 3.

NDE

Non-Destructive Examinations
Custom Air Coolers is approved for several different Non-Destructive Examinations, which is the act of evaluating a welded component (or material to be welded) without affecting the serviceability of the part or material.
Magnetic Particle Inspection (MT):
Commonly referred to as Magnaflux testing, is only effective at checking for flaws located at or near the surface. MT uses a metallic powder or liquid along with strong magnetic field probes to locate flaws (Particles will align along voids). MT can only be used on materials that can be magnetized.
Liquid (Dye) Penetrant Inspection (PT):
Uses colored or fluorescent dye to check for surface flaws but will not show sub-surface flaws. PT can be used on both metallic and non-metallic surfaces such as ceramic, glass, plastic, and metal.
Ultrasonic Testing (UT):
Is a method of determining the size and location of discontinuities within a component using high frequency sound waves. Sound waves are sent through a transducer into the material and the shift in time required for their return or echo is plotted. Since ultrasonic waves will not travel through air, flaws will alter the echo pattern.
X-Ray Inspection (RT):
Also known as Radiographic Testing, a wave of energy will pass through most materials and develop the negative image of what it passes through on film. The x-ray picture is a permanent record of a weld used for quality inspection purposes. These inspections can reveal flaws deep within a component.
Hardness Testing:
A test to determine resistance to penetration. Also to determine weld and heat affected zone hardness per methods described in ASTM A-370.
