API 5L X65 PSL2 Pipe

API 5l X65 Seamless Pipe, PSL 1 X65 Carbon Steel Line Pipe suppliers

Covered under the ISO standard based API 5L specification are both welded as well as the API 5L X65 Seamless Pipes. Generally these API 5L X65 Asme Equivalent pipes can be manufactured from either alloy steel or carbon steel. A prime reason why our buyers prefer using the Carbon steel specified API 5L X65 Material pipes is because they tend to be low in cost in comparison to the other categories of metals and steels. Additionally the low alloying cost of API 5L X65 Dsaw Pipe, is also what contributes to the affordability of these pipes. At Trident Steel & Engg. Co., the API 5L X65 Carbon Steel we supply is not only known to be affordable, but also for their strength and durability properties. However, in those applications, where our buyer’s primary concern is corrosion resistance, we also supply FBE Coated API 5L X65 PSL 1 pipes. The FBE coated API 5L Grade X65q carbon steel pipes are able to resist corrosion. Hence, our buyers use the API 5L X65 Nace pipes for piping based applications in industries like petrochemical along with oil and gas industries. When the PSL 2 API 5L X65 Pipe which we supply is used in various key applications, these pipes are very often appreciated for their good performance. For example, take the API 5L X65 Sour Service pipes, when used in sour wells – they have an admirable performance. In sour service conditions sulphur gets deposited on the inner walls of the pipe. Over time, the deposition increases causing a load on the pipes, thereby being susceptible to hydrogen sulphide stress related corrosion cracking. Since our clients note that the API 5L Grade X65 PSL2 has the ability to withstand and resist hydrogen sulphide stress related corrosion cracking, our buyers use the API 5L Grade X65 Pipe over the other steel grade pipes.
