API 5L DSAW PIPES

API 5L DSAW PIPES

API 5L Dsaw Pipes-

We can help supply all of the API-5L DSAW Pipes or linepipe supplies that your company needs for use in the oil or natural gas industries. API 5L Line Pipe Specifications for these pipes regulate usage for standard Grade A and Grade B pipes, with Grade X indicating stronger variants for drilling, production and transport requirements for offshore, arctic, deep well or harsher environments. Longitudinally welded steel pipes / Carbon Steel SAW Pipes are used in onshore and offshore oil and gas pipelines requiring critical service, high performance and tight tolerances.

With more than 20 years of combined experience, vast industry knowledge, competitive prices, the ability to procure hard-to-find products and fast delivery, we help you complete your projects on time and on budget.Double submerged arc welded pipe (DSAW) derives its name from the welding process wherein the welding arc is submerged in flux while the welding takes place. Both inside and outside welds are required and are usually accomplished in separate processes, hence the word “double.” These separate welds consume a portion of the other resulting in a single high quality weld nugget.

DSAW pipe is produced in sizes from 18″ through 72″ OD and wall thicknesses from .250″ through 1.5″.

Two different processes are used to manufacture DSAW pipe; the “Pyramid Rolls” method, and the “UOE” (U-ing, O-ing and Expanding) method. The difference in the processes is found only in the method of forming the cylinder. In the Pyramid Rolls process the cylinder is formed between 3 rolls arranged in a pyramidal fashion. The UOE method uses a “U” press, and “O″ press for forming the cylinder. The finishing and inspection processes are similar, and both methods use a flat steel plate as the raw material.

DSAW pipe may or may not be cold expanded. Cold expansion is a process where the pipe is expanded (up to 1.5%) to obtain its final OD dimension. In the process, a gain of yield strength results. Expansion is most often utilized in a UOE mill due to the need to recover yield strength lost during forming in the “O” press. DSAW pipe is available in the following grades: ASTM A134, A139, A252, A671, A672, A690, A691, CSA (Canadian) – Z245.1 and custom specifications. API 2B, 5LB, 5L X42 – 5L X80

DSAW pipe is normally produced in double random lengths with square ends or beveled ends. It is usually furnished bare but varnished pipe is also offered. A wide range of external coatings and internal linings are available with DSAW pipe.
