    Description:

    ASTM A106 Seamless Carbon Steel Pipe for High Temperature Service

    API 5L Specification for Line Pipe

    Application:
    Used for construction of long distance pipelines for combustible liquids and gases, nuclear station pipelines, heating system pipelines, general-purpose pipelines, vessels manufacturing, mechanical engineering and instrumental engineering.

    DISTINCTIVES FEATURES:

    Line pipe is manufactured of metal in-house produced and smelted in the electric furnace, treated with synthetic slags and cast by continuous casters. The applied steel making process ensures the achievement of chemically pure steel with reference to sulphur and phosphor contents providing high tensile, ductility and corrosion resistance properties of pipes to be operated at low temperatures in various corrosion media.

    Rolling using a press piercing mill and continuous mill equipped with a fixed mandrel allows strict measurement tolerances to be obtained and ensures a lack of pipe body and surface defects.

    In order to achieve high tensile and ductility steel as well as its required structure, providing a high corrosion resistance in various corrosion media, pipes are heat treated in a computerized walking beam furnace. 70% of oil line pipes are subject to heat treatment.

    Pipes are inspected for internal and external flows by automatic non-distructive testing of ultrasonic and electromagnetic inspection. Pipe ends inspection after beveling is done by magnetic-fluoroscopic flaw detection.

    While manufacturing seamless line pipes ensures testing of corrosion-resistance properties through hydrogen included cracking method under NACE MR 02-84 and sulphide stress corrosion cracking method under NACE MR 01-77.

    All hot-finishing processes are done and completed above a temperature of 860ºC. The hardness of the material is in all instances below 22HRc, thus complying with the NACE MR 01-75 requirement for carbon steels.
