elevated temperature mechanical properties of line pipe steels


High strength line pipe steels belong to the large category of metals that exhibit two stages of strain hardening (also called double-n behaviour) [8]. An accurate description and determination of this stress-strain behaviour and the toughness properties of line pipe steels is a key point in performing a strain based assessment [1, 7].

API 5L X56 PSL1/ PSL2 Carbon Steel Pipe manufacturer

What is X56 Pipe? Chemically, API 5L X56 PSL1 Pipe majorly contain alloying materials like 0.16% carbon, 0.45% silicon and 1.65% Manganese. All X56 Carbon Steel Pipe such as API 5L X56 Erw, X56 Line Pipe, X56 Lsaw Pipe, X56 Seamless Pipe & API 5L X56 PSL 1 Pipe also contain trace amounts of elements like 0.020 % Phosphorus, 0.010 % sulphur, 0.07% vanadium, 0.05% Niobium and 0.04% ASTM A335 P11 Seamless Pipe - metalspipingThe seamless pipe of ASTM A335 P11 is a typical Cr-Mo alloy steel pipe for high-temperature service. Also known as 1.25Cr-0.5Mo, the UNS designation of ASTM A335 P11 is K11597. Its ASTM equivalent includes ASTM A369 FP11 as well as ASTM A213 T11. Usually, the pipe shall be furnished with either butt welding(BW) or plain ends(PE).

Comparing materials for high-temperature steam piping

  • X20 MaterialP91 MaterialComparison of X20 and P91A Promising FutureNotesX20 material was first used in India for high-temperature steam piping around 1970. The next application in India took place nearly two decades later, when the Tata Electric Co. (tata) selected the material for both the main steam and hot reheat lines of its Trombay power station's 500-MW units. The use of X20 in preference to P22 (2-1/4 percent chromium, 1 percent molybdenum) in the latter application allowed wall thickness reductions of about 50 percent. These reductions resulted in ea Latest developments in mechanical properties and DOI:10.21825/SCAD.V4I1.742 Corpus ID:55278418.

D. Waele and D. Vanderschueren and Stijn Effect of Reduction Ratio below Austenite In this study, thermo-mechanical rolling trials were performed at the temperature below the recrystallization temperature of austenite on an API X70M PSL2 grade steel, which is large scale used in the oil and natural gas line pipes, to increase the strength without sacrificing the toughness.

    The Short and Long Term Effects of Elevated Temperature on

    Nov 10, 2016 · The mechanical properties of six industrially produced pipeline steels equivalent to API X52, X60, and X70 specifications were evaluated in the temperature range of 200350 °C. The steels were tested in uniaxial tension at strain rates of 10 4 and 8 × 10 4 s 1 in the as-received condition and after a low temperature 100 h aging process under a 419 MPa tensile stress. levated-Temperature Characteristics of Engineering Stainless steels for elevated-temperature appli­ cations include ferritic, martensitic, precipitation­ hardening, and austenitic grades. Next to the su­ peralloys, the stainless steels provide the best combination of high-temperature corrosion resis­ tance and high-temperature mechanical strength of any alloy group.
