PSI Custom Casing Spacers

Custom casing spacers may be manufactured to customer specifications to accommodate several pipes, conduits, cables or any other cylindrical item that needs to be inserted into the casing along with the carrier pipe.

Multiple Casing Spacers – Custom


Pipeline Seal and Insulator is the industry leader in the design and fabrication of multiple carrier spacers used for inserting different size pipes, conduits and wires into casings. Projects have ranged from simple dual pipe configurations to complex pipe/conduit arrangements, designed for maximum strength and efficiency within all pipe specifications.

Customized spacers are also available with electrically isolated rollers to ease installation of unusually heavy carrier pipes or for extremely long casing pipe runs.

PSI Models A (painted), C (coated) or S (stainless steel) may be designed and fabricated to meet the needs of your custom project.

All custom multiple carrier spacers share the same features as our single carrier spacers described throughout this web site. However, the multiple carrier spacers are considerably more complex and therefore require more detailed design considerations. Please contact Allied Corrosion Industries during your design phase.
