Quick Connect for Mining

Fast and Reliable Casing Solutions for Mining Applications

At MITO, we collaborate closely with our customers to understand their operational needs and offer a full suite of casing equipment and accessories. MITO has specifically designed casing with speed in mind, introducing Welda Quick Connect, a high-performing, flush connection for Mining applications.

Welda is an innovative quick connection designed with a blunt start and 3 thread per Inch (TPI) coarse thread to deliver quick and easy make-up in less than 7 turns. To help you run casing faster, the connector is a submerged arc welded to the pipe body to ensure a weld that is tough and reliable. Welda has undergone a series of qualification testing including Non-Destructive Testing, Make and Break, Torque, Tensile and Hydrostatic Tests.

In addition to Welda, MITO has a range of API connection OCTG products and accessories to suit mining applications.

  • 3 thread per Inch (TPI) with taper of 0.5 degree for easy and accurate stab.
  • Fast make up (less than 7 turns) and reduced cross threading.
