Here at All Spec Piping we've got you and your needs covered.

Prefabricating pipe spools in a controlled shop environment is much more efficient than the headache of fabricating everything at the jobsite. All Spec Piping can help you plan how to effectively use prefabbed pipe to stay on schedule and under budget.

Also, some other piping methods which use mechanical joints can be less cost effective than prefabricated WELDED pipe, especially for pipe diameters greater than 6". We can provide a better product at a better price.
