API 5l x65 pipe

API 5L X65 Pipe

Industrial applications have various requirements for metallic pipes. Metallic pipes are made from commercially pure metals to complicated alloys. To make sure that the manufacturers and the end users have the same idea about a particular pipe, there are standards and specifications set forth by international standards organizations. The API 5L is a standard specification for oil and gas line pipes and sour services. API 5L X65 Pipe is made in a grade X65 which has a minimum yield strength of 65ksi, which is denoted by its name. There are other grades in this specification as well. But the api x65 pipe is made unique due to the composition, production methods and heat treatment types.

Find an importer of x65 seamless pipe that provides MTC and the option to cut to length, and inquire about the working environment.

Since the pipes are carbon steel and can withstand high pressure and temperature, the api5lx65 pipe can be worked under room temperature. The pipes also can be hot and cold galvanized to improve surface resistance. The x65 pipe suppliers provide different coating options, matching, and forming options as well.

The density of any metallic alloy involves the composition of the alloy. The steel api 5l x65 pipe has carbon, manganese, phosphorus, sulfur, vanadium, niobium, and titanium in the composition. The composition gives the alloy 7850kg/m3 density. Higher pipe density also influences the x65 smys, which is the specified minimum yield strength. The smys for the X65 pipe is 65ksi.

The 1.7% manganese, carbon, silicon, and the other alloys give the api 5l gr x65 psl 2 pipe higher corrosion resistance. The corrosion resistance allows the pipes to last longer, especially in sour services and in onshore and offshore conditions. The x65 carbon steel pipe is therefore used in oil refineries, oil, and gas pipelines, and in other sour service applications.

Are you looking for tested, recognized API 5l x65 carbon steel pipe distributors? See API 5l x65 psl1 vs. Psl2

The produce specification level, PS1 is the normal standard for the api x65 steel pipe whereas the PSL2 is meant for even astringent qualities. Within a single piping system, there might be requirements for different pipes. So the psl1 and psl 2 of the api 5l x65 carbon steel pipe can be used within the same system for various components.

All international standards are met by the API 5l x65 tube, which is available on Schedules std, 40, 80, 20, 60, and XXS. Look into the API x65 steel pipe sour service application

The sour services are under an environment that has higher oxidizing conditions. The x65 seamless pipe has to operate under salty air and humid conditions. The surface finish, the corrosion resistance, and the abrasion resistance of the material stand against sour-induced corrosion. Therefore the pipes are suitable for sour services.
