API 5L X60 Pipe Specifications (PSL1 & PSL2) - Octal Steel

API 5L X60 is a common high grade pipe material in API 5L specifciations for oil and gas transmissions. Its also called L415 pipe, which named by yield strength minimum in 415 Mpa (60,200 psi).It covers manufacturing types in seamless (hot rolled and colde rolled), and welded in ERW, LSAW, SSAW (HSAW).. API 5L X60 pipe ranges in PSL1, PSL2, onshore/offshore, and sour service. AVESTA WELDING MANUALappropriate consumables and methods for welding stainless steels, it is hoped that the Avesta Welding Manual reflects this position. Stainless steel welding is a complex mixture of metallurgy, chemistry, geometry and aesthetics. The welds properties, e.g. corrosion resistance, have to be correct and the right surface finish has to be achieved.

Experimental phase balance assessment for duplex stainless

Experimental phase balance assessment for duplex stainless steel welded pipe. This paper discusses the assessment of weld metal ferrite content in duplex stainless steel pipe welded at a 45angle. The mechanical and corrosion properties of the weld joint depend on the proportion of ferrite and austenite phases in the microstructure. Grade X70 - an overview ScienceDirect TopicsProperties of 682.4-mm OD × 15.9 mm WT, API Grade X70 linepipe. A large offshore project in grade X70 is the pipeline in the North Sea operated by Statoil, connecting Karstø, Norway, with Dornum, Germany. This pipeline has a length of 600 km and it is built of pipe 42 in. × 2530 mm WT. In the 1990s, Europipe completed the development of

Therefore steel used for line pipe fabrication are fine grained with ASTM grain size number 7 or finer as per ASTM E 112. Concast Steel:Steel shall be made by continuous casting only to achieve improved yield, quality, productivity and cost efficiency.

X70 pipeline steel base metal, the weld bead and heat affected zone. The result obtained showed that the base metal have equiax ferrite grains while the weld bead have structure of acicular ferrite and fine bainite grains with manyAl -Si-Mn-Ti oxide particles/inclusions. The heat affected zone Machined Weld Rings - Imperial Weld Ring Corp., Elizabeth, NJOur custom weld rings can be machined to fit any standard or non-standard pipe or tube dimensions. We offer a variety of profiles that are designed to meet multiple pipe welding applications. Rings can be produced in mild steel, stainless steel, duplex, aluminum, copper-nickel (C71500 70/30, C70600 90/10), chrome-moly, nickel alloys, and

Weld Properties of Low Carbon Steel Using Shielded Metal

The choice of electrode for SMAW lies on a number of factors, like weld material, welding direction and the preferred weld properties. The present paper investigate the microstructure and hardness properties of the Low carbon steel pipe welded using shielded metal arc welding with different electrode combinations. Weldability of Steel The Metal Press by onlinemetalsNickel steel is a specific type of Alloy Steel that is unusual enough that it gets its own entry. Alloys contain 1-3% nickel may be carefully welded with low hydrogen welding processes. As the nickel content increases, the steels hardness increases. Like carbon, this means the weldability of

Welding - Steel Construction

Welding is a core activity in the fabrication factory, undertaken by skilled, qualified operatives working to a welding quality management system under the control of a Responsible Welding Coordinator. It is used to prepare joints for connection in the shop and on Welding Pressure Pipeliners and Piping SystemsThis booklet is a guide to welding pipe with Shielded Metal Arc Welding (SMAW) and double ending pipe using automatic welding. Lincoln Electric supplies electrodes, power sources, automatic and semiautomatic wire feeders, submerged arc wire and flux, which are the industry standards for pipeline construction around the world.

Welding of Stainless Steel and Other Joining Methods

Stainless Steel Welding Characteristics By definition, stainless steels are iron-base alloys containing 10% or more chromium, which imparts to the metal the corrosion-resistant properties for which stainless steels are so highly regarded. The chromium content may be increased and other alloying elements added or adjusted to meet specific end- Welding of austenitic stainless steels for cryogenic LNG Before setting up the requirements for LNG weldments the general mechanical properties of the austenitic steel and the main influences on the achieved test data have to be discussed. 2 Strength properties austenitic steels for LNG application Strength design is primarily done using room temperature properties.
