Piping Systems


Aero-Flex Corp. specializes in the fabrication of simple and complex ASME certified piping assemblies.  We can fabricate pipe sizes that range from 1/4″ up to 14″ in diameter and wall thickness that range from schedule 10 up to schedule 160. As a minimum we provide ASME quality level piping assemblies and can qualify to a company specific standard when required.

We have a CWI on staff that inspects each weld in process and during final QC inspection. We can provide radiographic inspection (X-Ray), liquid penetrant inspection, magnetic particle inspection and standard or high purity cleaning to any of the assemblies we build.

ASME Process Piping

ASME’s process piping code provides specifications for the pressure 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 consideration for pipe fabrication. The corrosion resistance required affects the pipe wall thickness as well as the selection of pipe materials. ASME 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  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. Fittings and flanges are also covered in ASME with specifications for temperature requirements, materials, and pressures.

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.

The Aero-Flex Touch

After welding all of our piping assemblies are individually pressure tested and cleaned inside and out. During cleaning we apply a degreaser 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 your weld will not rust in the field and will be nice and shiny for many years to come. Take a look at the pictures to the left and look at how they look after pickling.

In most cases piping systems serve as the backbone for multi-million dollar operations. Additionally your piping system has to withstand extreme circumstances from high pressures and temperatures to extremely corrosive environments.

In any event you can’t have just anyone fabricate your piping system. The Aero-Flex team has over 75 years of experience in these types of applications and the specifications required to deliver a piping system that will perform to your expectations.
