Carbon and high-strength low alloy steels meant for structural purposes in various forms, plates and bars are covered by specification ASTM A709. These components are first quenched, following which the alloy steel is tempered. The use of these structural plates or ASTM A709-50W Corten Steel Welded Pipe is specifically designed for use in bridges. About Us - Jain Steels CorporationAbout Us.

However, the high carbon content poses problems for welding, making the steel unsuitable for oil and gas transmission lines. Definition Of Duplex Steels - Metal & Oil & Gas News Sep 06, 2013 · Duplex Stainless Steels Are Extremely Corrosion Resistant, Work Hardenable Alloys. Their Microstructures Consist Of A Mixture Of Austenite And Ferrite Phases. As A Result, Duplex Stainless Steels Display Properties Characteristic Of Both Austenitic And Ferritic Stainless Steels. This Combination Of Properties Can Mean Some Compromise When Compared With Pure Austenitic And
Gas and oil pipelines for the Arctic region must sustain low temperatures and high internal pressures of a corrosive active medium. Generation of new steel compositions for oil and gas pipelines is an urgent issue in order to ensure their high reliability. Low-carbon steels with a ferriticpearlitic structure are normally used in pipe production, but they are unable to cope with increased Lap Joint Flange Supplier of Quality Forged Fittings-FlangesSurface treatment:Transparent oil, rust-proof black oil or hot galvanized Standard:ANSI, MSS, API, AWWA, DIN, JIS, BS and GB. Related Products. API 5L B Steel Pipe We supply API 5L B PSL 1 and PSL 2 steel pipe for industrial use kinds of seamless and welded. Nickel-containing alloy piping for offshore oil and gas Interest in the use of stainless steels for seawater systems developed in Norway11 where, in concrete gravity platforms, which incorporate oil storage/seawater ballast tanks in their base, problems developed in cement-lined steel ballast pip-ing. This piping is alternately exposed to seawater and crude oil containing some sulphides.

An attempt was made in present work to improve strength and hardness of a 0.20% C steel by quenching it in cold water and oil. The present work was further extended to the study of tempering Susceptibility to SOHIC for Linepipe/Pressure Vessel Steels
- Industrial ExperienceDiscussionConclusionsReferencesAn attempt has been made to collate information on instances of SOHIC which have occurred in industry. In doing this, only failures in which there is a fair degree of certainty that the primary mechanism was SOHIC have been included. Even so, the available information has not always been sufficient to make an independent judgement, and reported diagnoses have had to be accepted in some cases. Information has been sought from companies through an EFC/EPERC survey and by direct request to selected coDuplex Steel 2205 :Application or Typical ApplicationsDuplex Steel 2205 (UNS S31803) Pipes, Tubes, Fittings, Flanges, Fasteners, Plates and Bar :Agent, Exporter, Dealer, Distributor, Stockist, Stockholder and Supplier in India :Duplex stainless steels are typically used in:~ Chemical processing, transport and storage ~ Generally where 304 and 316L are used ~ Oil and gas exploration and offshore

Most of the oil and gas resources contain H2S or / and CO2. Among them, some oil and gas wells contain only H2S or only CO2, while more oil and gas wells contain both H2S and CO2. For the corrosion and protection problems containing only H2S, over 50 years, a lot of research has been done, the corrosion mechanism is relatively clear
