Checklist : Pipe Rack Design


During design of Pipe Rack, certain points need to be taken into consideration for optimal design. Some of these points are covered in following pipe rack design checklist. This checklist can be used at design stage as well as during 3D Model Review.

Sr.No. Point to Check Done
1 25% Extra space provided for future expansion
2 Minimum 3* Meters clearance provided below Units Pipe racks not crossing any roads.
3 Minimum 2.2* Meters clearance provided below offsite pipe racks not crossing any roads. (Only for Walking below).
