There are several reasons that make grade X80 one of the more stronger carbon steel pipes under the API 5L specification. Firstly, the checks performed on API 5L Grade X80 PSL 2 pipes are more through and every pipe produced is checked. Secondly, the chemistry is followed through with very narrow tolerance values. However, the content of carbon could be modified with if the pipe to be made via a welded construction.
Api 5l X80 Pipes made via welding can be processed to such a degree that the longitudinal weld seam made on the body is reduced. This procedure is practised by several manufacturers to avail good quality welded pipes at an affordable cost. Though it is important for businesses to vet their manufacturer or supplier prior to purchasing an Api 5l X80 Line Pipe, as an improperly welded product is not only susceptible to getting attacked by intergranular corrosion on the weld seam, but also getting cracked. These issues are not seen in a product like the Api 5l X80 Seamless Pipe. Though the cost of choosing a seamless product over a welded one is a more expensive one. But cost aside, the performance of a seamless variety Api 5l X80 Psl2 pipe is much better than a PSL 1 pipe as the tolerance is much lower, thus ensuring only good quality pipes are supplied to the buyer.
