General Purpose Fiberglass Epoxy Tubing

For more than 40 years Amalga has produced composite tubing as an alternative to metal tubing. Constructed of fiber reinforced thermoset epoxy resin, fiberglass epoxy tubing (CL) can be used in a variety of structural applications. The results: A light weight, high strength, corrosion resistant material which replaces carbon steel, chromed steel, stainless steel, aluminum or brass in a wide variety of applications.

Fiberglass/Epoxy tubing (CL) is constructed of fiber reinforced thermoset epoxy resin. CL is a light weight, high strength, corrosion resistant material which replaces steel, aluminum or brass in a wide variety of applications.

Key features of Fiberglass Epoxy Tubing

Key features of Fiberglass Epoxy Tubing include:

75% Reduction in Weight

Fiberglass epoxy tubing reduces material handling and shipping costs. Approximately 1/4 the weight of steel or brass and 3/4 the weight of aluminum, fiberglass epoxy tubing is much easier to handle than traditional metal tubing. Assembly times are reduced and stress loads on component parts are decreased.

Superior Corrosion Resistance

Trouble-free performance in chemical, high moisture and other adverse environments including salt and chlorinated water which results in significant reduction in life cycle costs.

Electrical Insulator

Can be used in applications to prevent the flow of electric current.

Storage Capacity

We can stock products to meet your JIT, MRP, or KAN BAN requirements.

Transparent to x-rays, radio and television transmission

Fiberglass epoxy tubing can be used as a radome because it is not affected by electromagnetic radiation.

Shape Stability and Impact Resistance

Ship, store and cut fiberglass epoxy tubing, it will retain its circular shape. Unlike metals, the product does not dent. Material impact strength is 40 lzod ft-lbs.

Excellent Thermal Stability

With a very low coefficient of thermal expansion, fiberglass epoxy tubing operates efficiently up to 250 °F and customers have reported success in using our product at temperatures below -50 °F.

Non-Magnetic Material

Can be used in magnetic fields without concern of interference. It is ideal for Magnetic Resonance Imaging (MRI) applications.

Standard Sizes

Fiberglass Epoxy Tubing is available in a range of standard sizes. These can be specified with either standard bore sizes or standard wall thicknesses. For more information on standard size Fiberglass Epoxy Tubing, click here.
