Experience Is Key:

Aero-Flex has extensive experience in fabricating complex custom process piping and power piping spools including complete piping systems. You can find our piping systems and assemblies on some of the largest oil & gas and power turbine companies in the world including GE Power and GE Oil & Gas along with Pratt & Whitney Power Systems among others.

 Our CWI (certified weld inspector) is on the floor throughout the fabrication process making sure all welds are performed within spec and all assemblies get a final check for accuracy in quality before being signed off for shipment to our customers. We have a certified NDT expert on staff to perform penetrant inspections  and Aero-Flex has a certified NDT lab that performs all radiograph (X-Ray) inspections when required.

Power Piping

The Aero-Flex Touch:

After welding our piping assemblies are individually pressure tested and cleaned inside and out. During cleaning we apply a de-greaser to clean the pipe and a pickling acid on the welds. The pickling acid pulls the carbon out of the weld and brings it to the surface. Then we scrub the welds to remove the carbon and other impurities. This ensures the weld will not rust or deteriorate for years to come. Take a look at the pictures and see how they look after pickling.

In any event you can’t have just anyone fabricate your process piping or power piping spools. The Aero-Flex team has over 75 years of experience in metal fabrication and welding along with the understanding of the specifications required to deliver a process piping system that will perform to your expectations.

ASME Pipe Welding

What Is ASME Process Piping?

ASME’s piping code provides specifications for the design requirements of high pressure piping. This is to ensure that the pipe can safely meet the demands and stresses that will be placed on it while in service. The code also sets standards for material selection, support design, thermal expansion, examination, and testing. Corrosion resistance is a major factor for pipe fabrication. The corrosion resistance required affects the pipe wall thickness and the selection of pipe materials. An ASME pipe process uses different subsections to address corrosion allowance for different piping specifications (PS). These are specified by the PS-number.

Connections in pipes are among the most common sources of failure. ASME process piping addresses what types of connections are permitted and what type are not. It also addresses when welded branch connections will need to be reinforced and what types of welded fittings may be used. Butt-Weld Pipe fittings and flanges are covered in ASME with specifications for temperature requirements, materials, and pressures. Typically ASME B16.5 pipe flanges are used where flanged connections are required. Pressure testing is crucial to ensure the integrity and performance of your piping assembly. ASME sets hydrostatic test limits that specify different minimum test pressure specifications for different design pressures and temperatures. Hydrostatic testing may need to be performed on fittings, valves, and instruments separately to ensure compliance.
