Important points related to Exhaust Pipe Supports Erection

Here are the very simple but important points to be followed during exhaust pipe supports erection...

1. Anchor Fastener:

An anchor bolt is used to attach objects or structures to concrete. There are many types of anchor bolts, consisting of designs that are mostly proprietary to the manufacturing companies. All consist of a threaded end, to which a nut and washer can be attached for the external load. Anchor bolts are extensively used on all types of projects, from standard buildings to dams and nuclear power plants. They can also be used to firmly affix embed plates to a concrete foundation when used with a structural steel element.

In simple terms, exhaust pipe can be erected in desired directions using MS Supports fixed in appropriate places with the help of welding and anchor bolts. Anchor fasteners( also called anchor bolts) should be anchored(hammered) to concrete beam , pillar and concrete ceiling but not to brick walls. One has to ensure that fastener is properly fixed inside concrete as per specifications, before going for another one. Pin type anchor fasteners are recommended to the ground level supports, whereas tapper or Fischer type anchor fasteners are recommended for ceiling level supports fixing.

2. In case of MS exhaust pipe erection with in structure or building shaft area, a support at every 3 meters is required for vertical erection of pipe, whereas if the pipe is vertically erected along building wall, then a support at every 2 to 2.5 meter is recommended. If the pipe is erected horizontally then a support at every 2 meter is necessary since supports has to hold/share the total weight of the pipe's layed. Upto 200mm round pipe 75 x 40 x 6mm MS Channel, above 200mm round pipe 100 x 50 x 6mm MS Channel supports should be considered. If the pipe is heavier and also series of pipe's to be layed side by side then a 100 x 50 x 6mm MS Channel box support or heavier size channel is recommended.

3. In case of constructing fly over bridge (near road crossing) from the bottom of the ground for series of exhaust pipe horizontal erection then MS i-beam should be considered for bridge supports erection. The base-plate of the each pillar of the bridge should be fixed to the foundation bolts grouted inside concrete.

These are very important points to be taken into consideration before erection of exhaust pipe supports.
