Special applications. On request casing spacers can be manufactured in other types of plastic material according to the temperature and mechanical requirements of the application.
Raci Casing Spacers are divided into 3 groups which address a wide range of pipe sizes, and weights.
Individual spacers within each group have specific load carrying capacities. The tables below state these figures with a built in safety factor. All of these factors must be verified to determine the best casing spacer type for the application.
Distance between spacers must be calculated so the maximum load per spacer ring does not exceed the maximum load carrying capacity for the type used as shown in the tables. Maximum load per casing spacer is calculated based on the weight of the pipe filled with liquid divided by the number of casing spacer rings installed.
The maximum distance of 10 feet / 3 meters shall not be exceeded due to the danger of the pipe sagging between the spacers support points unless the pipe manufacturer states differently.

Casing Spacer Extensions
When a higher element height is required, extensions are available in 146, 171, and 197 mm (5.75, 6.73 and 7.76 inches) heights. These extensions fit easily over the regular casing spacer projections. Contact a distributor for more information.
Special Applications
On request casing spacers can be manufactured in other types of plastic material according to the mechanical and temperature requirements of the application.
