For most pressure vessels, the cost of shipping is not more than a few percent of the total cost, yet even that is enough that it should be considered in the price of the product. For products that are extremely large or extremely heavy, however, that percentage may increase.

The size and load capacity of standard rail cars facilitate shipment of many vessels that might require permits as wide, long, or heavy loads if shipped by truck. Rail rates (per pound) are often much less than truck rates. Barges even more so, if the size of the product justifies them. This is especially the case if permits or special routing are needed for trucking. Rail shipments often take longer than trucks, however, due to the way that rail traffic is routed.

In any case, unless the estimator is confident of knowing shipping costs with a good degree of accuracy, it would be good to verify costs with shippers prior to bidding a job. See Chapter 11 for more information regarding shipping.
