Definition - What does Hydroforming mean?

Hydroforming is a cost-effective technique of converting the shape of ductile metals such as alloy steel, stainless steel, aluminum, brass and copper into lightweight, strong and structurally stiff pieces. This technique can also be referred as metal fabricating and forming technique. Automobile industries make use of this technique on a large scale. Similarly bicycle manufacturing industries also make use of hydroforming for production of bicycle frames.

Petropedia explains Hydroforming

Hydroforming has always been an effective solution of forming and fabricating metals into required shapes. This technique has now been seen as one of the important technological advancement in the safety of marine life because of the failure of offshore wells and oil spills in oceans by oil and gas industries. After the Gulf Coast Oil spill disaster and increased environmental scrutiny by regulatory authorities on offshore O&G industry, integrity and maintenance of offshore (under sea) wells has become very important.

After the immense success of Hydroforming in automobile space, engineers have started deploying this technique for the maintenance of offshore wells as well. In the hydroforming process, a metal sheet is kept on a specialized die molding and then with the help of highly pressurized fluid, the metal is formed into a required shape. Inspired by hydroforming and taking advantage of the natural hydraulic pressure generated by the offshore drilling rigs at site, engineers have developed a process called Metalmorphology, which allows engineers to form the metal component after it has been already inserted into the borehole. The metal is formed inside the borehole into the required shape by the application of natural hydraulic pressure created by the offshore drilling rig.
