With our new Simplified Frac Iron System, Weir Oil & Gas has dramatically reduced the amount of iron on the frac site, replacing multiple iron strings, numerous turns and connections found in traditional configurations with a safer, straighter, more streamlined large-bore design.
Reduced non-productive time and costs
Customized to any basin or condition, this system is designed to improve safety and performance, minimize pressure-drop and erosion—thus extending equipment life—and reduce non-productive time, rig-up time, and material and labor costs.
Fewer leak paths, greater reliability
Throughout Weir Oil & Gas’ Simplified Frac Iron System, we’ve replaced the numerous hammer-union connections with safer API-6A flange connections. These standardized connections, which rarely require tightening in the field, feature reliable metal-seal gaskets—and since there are fewer of them, we have dramatically reduced the number of potential leak paths.
Faster rig-up
The linear, large-bore design of the system’s pressure control components, several of which have patents pending, vastly simplifies and shortens the rig-up process. Single inlets and outlets replace multiple tie-in lines. Adjustable spools and rotating flanges allow for quick alignment between the zipper manifold, the frac tree, and the trunk line.
Less fluid turbulence
Directional fluid changes, which create accelerated wear and pressure drop in demanding conditions, are also minimized by the one-straight-line design, extending product life.
Field-tested, field-proven
In a recent field test, the pressure-control components of Weir’s Simplified Frac Iron System lasted more than three times longer than a competitor’s previous configuration, which also featured a single-line zipper tie-in.
The number of pipe connections was reduced from 100 to 12, eliminating the potential for leak paths by 88 percent (rig site set-up will vary total reduction). An internal CFD analysis of the Weir configuration predicted approximately 70 percent less pipe erosion compared to similar designs.
