POINTS TO BE CHECKED WHILE SUPPORTING

[PipingStudy.COM]

L-TYPE SUPPORT SHOULD BE AVOIDED FOR LINE SIZE GREATER THAN 4". IN CASE OF SMALL SIZE LINES, CANTILEVER OF SUPPORT SHOULD BE 1000mm (MAX.)

HORIZONTAL TRUNNION ON THE FLOOR SHOULD BE AVOIDED IF IT CREATS TRIPPING HAZARD. AS FAR AS POSSIBLE, PROVIDE TRUNNION BELOW THE STRUCTURE IN SUCH CASES.

IN CASE OF VERTICAL TRUNNION , HEIGHT SHOULD BE RESTRICTED TO 700mm (MAX.) IF THE DIFFERENCE BETWEEN BOP AND TOS IS MORE, THEN USE TEE-POST AND LESS HEIGHT TRUNNION. BUT GENERALLY WE SHOULD AVOID VERTICAL TRUNNION ON THE HORIZONTAL PIPE. WE CAN USE SHOE INSTEAD.

ALL THE STRUCTURAL SUPPORT (T-POST, L-POST, TRAPEEZ ETC.) SHOULD BE USED WITH MEMBER SIZES PROPORTIONAL TO LINE SIZE/ LOAD REQUIREMENT.

IN CASE OF STRESS CRITICAL LINES, THE NON STANDARD GAPS TO BE SPECIFIED IN SUPPORT SUMMARY AND SHALL BE VARIFIED BY STRESS ENGINEER.

AVOID HANGING SUPPORTS IN CASE OF HEIGHT MORE THAN 3000mm. OTHERWISE GUIDING OF THE PIPE HAS TO BE ENSURED.
