G 2T® lined wear pipe is a seamless, monolithic lined pipe designed to provide maximum abrasion resistance in the most challenging environments.

The G 2T lined pipes consist of a layer of engineered alumina ceramic material applied to the inside wear surfaces of the pipe, which is then spun cast or troweled in place. The result is a singular liner with no seams or tiles. After curing, the liner retains a hardness of between 8 and 9 on the Moh’s scale, yielding one of the best wear solutions for the most erosive applications. 

Our cast lined pipe has been engineered to provide unparalleled wear resistance in corrosive and high-temperature environments. The chemical composition and seamless application limit the effects of corrosion in many applications. The G 2T’s high-temperature capabilities and excellent thermal shock resistance can provide exceptional abrasion resistance that no other material can match in environments up to 2200° F. 

The combination of corrosion resistance and high-temperature capabilities provides unquestionable advantages over the most common pipe materials such as basalt, rubber, polyurethane, steel, cast iron, or ceramic tile.

Hardness Profile

The outside surface is mild steel for easy welding. The interior of the pipe is lined with engineered G 2T ceramic material for integrity. 

fabrication

We recommend the use of Clifton Steel’s fabrication services to eliminate processing and fabrication errors. 

Cutting

WARNING: Ceramic lined pipe must be supported on both sides of the cut area to prevent damage to the pipe and/or cutting equipment.

Ceramic lined pipe can be cut with an abrasive saw using an abrasive silicon carbide wheel. 

Joint Preparation

Inspect the surfaces to be welded- avoid welding areas that have tears, cracks, or other discontinuities. Clean the joint area, remove all loose scale, rust, moisture, grease, etc. within 1/2″ of welding joint. 

Liner Touch-up

Any chipped areas should be filled with G 2T from Clifton Steel. Allow for proper curing. 

Ceramic Lined Pipe

welding

1. general instructions

Working from the exterior of the pipe, join the pipes using a low carbon electrode. Allow the pipe to cool before proceeding. Our Tensaweld Workmate welding wire is compatible with the G 2T pipe. 

2. Preheating

If the ambient temperature of parts is below 70° F, preheat the weld zone and 6″ of adjacent materialto 100° F.

3. consumables

Any low carbon electrode is acceptable, 1/8″ or smaller should be used.
