Pvc Pipe Support Spacing Table Standards

Inches operating temperature of 60.

Pvc pipe support spacing table standards. Maximum support spacing feet nps. Center to center spacing 1 2 o d of the bigger size pipe flange insulation thickness of bigger size pipe if applicable 25 mm 1 2 o d of the smaller size pipe insulation thickness of smaller size pipe if applicable. Supports should at the very least be compliant with all codes and regulations you will face. Horizontal and vertical support for cpvc pipe mostplumbing codesandbuilding requiresupportfor horizontal pipe lines every 3 feet for pipe in 1 2 1 diameters and every 4 feet for pipe with diameters greater than 1.

Proper support selection and spacing is critical to prevent stress concentration areas as the result of weight loading bending stress the effects of thermal expansion contraction and to limit pipe displacement sag. Maximum support spacing for cpvc chlorinated poly vinyl chloride pipes depends on the operating temperature. The table below from as nzs 2032 shows the support spacing in metres for pvc pipe carrying water at 20 c. Pvc pipe schedule 40.

Lanl engineering standards manual pd342 chapter 17 pressure safety section d20 b31 3 g asme b31 3 process piping guide rev. In particular the application of asme b31 3 requires compliance with the inspector qualification. Spacing for vertical systems should usually be about two times the intervals in the table above. The span is 4 ft for pipe up to 6 ft for 4 schedule 40 pipe at ambient temperature.

If you are working on an inspected job you will also need to be aware of any specific code requirements for pipe support in your area. The basic principle for deciding the spacing the pipes running parallel to each other is. 2 3 10 09 4 the owner and designer are responsible for compliance with the personnel and process qualification requirements of the codes and standards. These spacings do not allow for additional extraneous loadings.

Cpvc pipes schedule 40 cpvc pipes schedule 80. Maximum spacing between supports at different temperatures can be found in the tables below. Approximately 1 ft more for schedule 80 and half that spacing at 150 f. However for the same class of pipes pvc o and pvc m will show increased deflection between the supports.

For pvc pipe the spacing depends on the pipe schedule and operating temperature.
