Casing Spacers

Stainless Steel Casing Spacers

The 8” wide or 12” wide stainless steel casing spacer shall be a two piece shell made from 14 gauge T-304 stainless steel. Each shell section shall have a flange formed with ribs for strength and with a minimum of three 5/16-inch stainless steel bolts for eight inch wide and four for twelve inch wide spacers.

Each shell shall be lined with a ribbed PVC extrusion with a retaining ridge that overlaps the shell to prevent slippage. Runner surface shall be UHMW polymer  or Glass Reinforced Polymer for abrasion resistance and a low coefficient of friction. The runners and risers shall be attached at appropriate positions to properly support the carrier within the casing and to ease installation.

The runners shall be attached mechanically with bolts and the bolt heads MIG welded for strength. All risers shall be 10 gauge T-304 stainless steel MIG welded to the shell.

Standard positioning within the casing will require the height of the runners and risers to be sufficient to provide clearance between the casing and the outside diameter of the bell or restrainer. Centered positioning within the casing will require the runners and risers to place the carrier pipe in the center of the casing and to provide a minimum clearance of 3/4-inch to the top of the casing.

Fusion Bonded Carbon Steel Casing Spacers

The 8” wide or 12” wide carbon steel casing spacer shall be a two piece shell made from 14 gauge pickled & oiled mild steel. Each shell section shall have a flange formed with ribs for strength and with a minimum of three 5/16-inch stainless steel bolts for eight inch wide and four for twelve inch wide spacers.

Each shell shall be lined with a ribbed PVC extrusion with a retaining ridge that overlaps the shell to prevent slippage. Runner surface shall be UHMW polymer  or Glass Reinforced Polymer for abrasion resistance and a low coefficient of friction.  The runners and risers shall be attached at appropriate positions to properly support the carrier within the casing and to ease installation.

All fusion bonded coated casing spacers are coated in a thermoplastic coating.

Carbon Steel Spyder Casing Spacer

This spacer is manufactured entirely of ASTM A-36 steel.  All joints are MIG welded and then coated with a thermoplastic powder.

KP and KC Polymer Casing Spacers

The BWM COMPANY offers a complete line of POLY spacers. We offer polymer spacers in sizes from 2-inch through 48-inch. Excellent dielectric resistance and low moisture absorption for minimal electric current loss and no impairment of catholic protection.

Poly spacers are manufactured by injection molding using high-density polyethylene, which provides high impact strength and a low coefficient of friction. Sections are used to construct all diameters. All runner configurations are engineered for a 6:1 load bearing safety factor. Runner heights come in various heights to provide clearance for bell and spigot connections.

BWM KP and KC spacers only require a screwdriver for installation and offer five advantages:

  • The molded legs can be manually cut on the cutting die built into every leg. This is a BWM exclusive which makes stocking our spacers a breeze.
  • Simple to install
  • No special tools required
  • Extra strong
  • Solid construction.
