  • Industrial coating with color-change responsivity to acid and base contact
    Patent number: 11680181
    Abstract: A latex-based surface coating that can be applied to the surface of equipment to detect any leaks of acid or base onto the equipment. The latex-based surface coating changes color when a strong acid and/or a strong base makes contact with the surface coating, thereby providing a visual indication that a leak of a strong acid and/or a strong base has occurred. The surface coating is able to provide visual indications for acids with a pH between 0 and 3 in the liquid or gas phase. The surface coating is also able to provide visual indications for bases with a pH between 9 and 14 in the liquid or gas phase.

  • Casing spacer with roller assembly guards
    Patent number: 11578823
    Abstract: A casing spacer that fits around a carrier pipe at various intervals along the length of the carrier pipe for the purpose of positioning the carrier pipe within a casing pipe. The casing spacer is equipped with roller assemblies on the outside surface of the casing spacer. The roller assemblies are protected by guards to help the roller assemblies avoid obstacles that may exist on the inner surface of the casing pipe.

  • Transparent flange protector
    Patent number: 6231052
    Abstract: A flange protector for protecting opposing flanges of a pipe joint from corrosion and leakage. The flange protector is comprised of a transparent, flexible, elastomeric band for wrapping around the periphery of the opposing pipe flanges of the pipe joint. The band has metal straps that support a fastener for pulling the ends of the band together tightly around the pipe flanges and lubrication inserts for injecting a lubricant through the transparent band to the surfaces of the flanges. The transparent band is sufficiently clear so as to allow visualization of the amount of the lubricant present at the flanged pipe joint and the presence of any corrosion of the flange surfaces without the removal of the flange protector from the flanged pipe joint.
