Incorporated in 1960, Harliss Specialties Corporation has
accumulated over 56 years of experience in the welding, machining and
fabrication business, offering custom fabrications from light gauge sheet metal
to heavy steel plate and structural weldments.

Our welders are qualified and certified to ASME Sec. IX for
all types of metals including Aluminum, Carbon Steel, Stainless Steel, Inconel,
Monel, Hastelloy, Titanium and Zirconium.

Our extensive fabricating, welding and machine shop
equipment is used to aid us in our desire for continued growth and to expand
our diversification to cope with the ever changing advances in technology.

ASME Code Vessels


    Harliss Specialties designs and builds tanks and heat exchangers to ASME Section VIII Div. I requirements. We have experience with registering code vessels with Canadian provinces, GOST certification and PED Requirements. We can also modify and repair pressure vessels using our “R” Stamp.

ASME / TEMA Heat Exchangers

Harliss is able to design Heat Exchangers to meet the TEMA and ASME code requirements. Thermal design is completed by using HTRI software and the mechanical design is completed using CEI Software.

Miniature Tanks

Harliss Specialties build miniature tanks either custom designed or designed based on our standard stock components. We manufacture miniature tanks in aluminum, hastelloy, monel, inconel, alloy 20, stainless steel or just carbon steel.

Forming

We are experts at rolling and forming. If need be we will design tooling to form your part. With our computer software we can develop, cut and form, any elbow, transition or cone you might need.

Machining

Our machine shop has a NC drilling machine, 72" boring mill, turret lathes, engine lathes and milling machines.
