Cleaning equipment recirculation pump

In addition to the drilling rig, a variety of support equipment may be required. Depending on the HDD project, a drilling fluid or mud cleaning and recirculation unit, drill pipe trailer, water truck, and pump and hoses may be required. An excavator is needed to dig the entry, exit, and recirculation pits. In urban or environmentally sensitive areas a vacuum truck may be required to handle the fluid in the return pits or inadvertent returns. 

This improves temperature control of the material In the lines and avoids settling of reinforcing materials when they are used. All lines should be designed to be self-draining to simplify machine clean out. Smooth inside surfaced flexible hoses lined with Teflon are preferred where flexible lines are required. Where these lines are jacketed, It is preferred that the jackets be coupled to the suction side of the recirculating oil pumps to keep the oil pressures low. Should leakage occur between the jacket and the reactant streams, then It is more likely that the reactants will leak into the oil than visa versa. Oil contamination will adversely affect nylon RIM reaction speed and physical properties. Many manufacturers of RIM equipment recommend that all tanks, valves and fittings for nylon RIM machines be made of stainless steel. Mild steel and...
