Standard wooden skid size

[leher258]

Dear Team,

Please advise regarding standard dimension details to select right size wooden skid for 36" Gas pipeline.


Thanks

Can you give us a little more information? Are you talking about a typical wood skid used with forktrucks or is this some type of wood platform supporting a gas line?

Thanks a lot Motorcity for the response. Yes exactly these are secondary supporting to Gas pipeline mostly needed to assembly the pipeline section until lowering in to trench.

They are std. 6"x6", 8"x8" (or some such), any length, hardwood cribbing materials. The same hardwood materials are used for working mats under heavy equipment or at concentrated work areas. Ask some of your local pipeline companies, or a local pipeline materials and equipment supply company. They can be spaced as you wish, stacked in alternating layers to a preferred height, cut to any length, and cut in short length with angled ends to keep pipe from rolling, and they can be easily transported down the line.

Many thanks dhengr for the response.
It's really helpful but why I'm floating the query actually to find some industrial standard length of skids. Commonly we can consider greater then OD of pipe but I would like to follow if any standards there so please confirm.

Leher258:
I don’t know of any industry stds., as such, although pipeline work isn’t my specialty. And, I don’t think what you are referring to is called a skid, it is more likely just cribbing or temporary support system for the pipe. This kind of stuff is pretty site and project specific and a matter of some engineering judgement and experience. Various pipe line companies probably have their own stds. and rules of thumb from their own experience. They will most likely reuse materials and equipment if they have another project in the same area, so this could come into play. Obviously, these cribbings have to be stable for the work involved, so they will likely be wider (pieces longer) than the o.d. of the pipe being worked on, maybe a foot or so on each side for larger pipes. Then, at the ground level, 2 pcs. (or more) of the 6" or 8" wide by x length timbers must provide enough soil bearing area for the loads being supported. Then the next timber layer is set perpendicular to the first at about the same width spacing, and the bearing area btwn. the timbers [4(6x6) or 4(8x8)] shouldn’t overstress the timbers in compression perpendicular to the grain. Someone within the company has done these types of calcs. enough times so he probably has a tabulation of various arrangements based on pipe size, pipe piece length, thickness, weight, and they know something about the soil conditions along the pipeline. And, this sets the cribbing arrangement and spacing. I suggested who you should talk with, they can probably give you better local answers than I can. Then, also, apply some of your own engineering knowledge or find someone local who can help you on this. That will be a good relationship to foster and develop.

dhengr,

Here again thanks a lot for the guidance.
