Friction welding is the process of choice for the oil and gas industries. It's proven reliability coupled with process advantages such as being clean, fast, consistent, and free of operator-induced error, makes friction welding one of the leading methods of joining flanges to valve bodies, drill pipe, high-pressure hose couplings, and manifold tubes.

How MTI is making a difference in oil and gas manufacturing

Harbison-Fischer, which specialises in subsurface oil field rod pumping processes, had an issue with an integral pump part that was taking too long to create and costing too much to produce and so MTI created a cost-cutting, time-reducing friction welding machine that met the client’s expectations. 

After teaming up with MTI, we applied our partnership process along with our experience in oilfield applications and this led to developing a friction welding machine that solved their problem by manufacturing the part with much higher quality while also saving them time and money. The experience also resulted in creating further innovations for this and other industries as well.

In response to client requirements, MTI were able to cut the client’s Monel consumption in half for this product process and in addition, Harbison-Fischer benefited from lower expenses and faster output because they were able to eliminate processes. MTI also created two new innovative tactics (quick change tooling and the shear die design on the machine) that may be used for other applications in different industries.

Proving once again that MTI are able to meet challenges in unchartered territory, the solutions directly cut costs for the client and the learning experiences throughout the process were crucial in delivering a first-rate friction welding machine. 




Why friction welding is vital in oil and gas applications

Since a typical string of drill pipe can be three to four miles long, composed of 30-foot sections, weld integrity is a must in the oil field drilling industry. The friction welds support the lower drill stem assembly (made up of other drill pipes, drill collars, and the drilling bit) and transmit the rotary torque needed for drilling.

Friction welding produces a metallurgical bond strong enough to take the high torque and highly loaded rotary tension due to directional drilling.
