Hot Rolled seamless steel pipe

- Apr 17, 2019-

Seamless steel tube for geologic drilling and oil drilling: to explore the structure of underground rock strata, groundwater, oil, fossil fuel and natural resource, the employment of drilling RIGS drilling.Drilling is indispensable for oil and fossil fuel exploitation. Seamless steel pipe used for oil drilling for geologic drilling is that the main drilling instrumentality, in the main as well as outer core pipe, inner core pipe, casing pipe, drill pipe, etc.Due to the pipe to travel deep into the thousands of meters formation depth work, operating conditions is incredibly complicated, drill pipe underneath pull, pressure, bending, torsion and uneven impact load stress, however conjointly by mud, rocks and wear, therefore, needs conduit should have spare strength, hardness, wear resistance and impact toughness, steel pipe steel with "DZ" pinyin "(geology) and beloved on behalf of the steel yield purpose, same common steel grade DZ45 MNB forty five, fifty mn;DZ50 40Mn2, 40Mn2Si;DZ55's 40Mn2Mo, 40MnVB;DZ60's 40MnMoB and DZ65's 27MnMoVB.All steel tubes are delivered in heat-treated condition.Petroleum cracking pipe: seamless pipe for furnaces, heat exchangers and pipelines in fossil fuel refineries.Commonly used prime quality steel (10, 20), steel (12CrMo, 15CrMo), heat resistant steel (12Cr2Mo, 15Cr5Mo), stainless-steel (1Cr18Ni9, 1Cr18Ni9Ti) producing.In addition to the chemical composition and numerous mechanical properties of the steel pipe, however conjointly to confirm that water pressure, flattening, like flaring take a look at, and surface quality and non-destructive scrutiny.Steel tubes to be delivered in heat treated condition.Stainless steel pipe: with every kind of stainless-steel hot rolled, cold rolled stainless-steel pipe, wide employed in fossil fuel, chemical instrumentality pipelines and numerous USES of stainless-steel structure components, additionally to the chemical composition and mechanical properties ought to be secured, wherever used as an impact fluid pressure steel pipe to confirm that the water pressure take a look at qualified.All kinds of special steel pipes shall be secured in keeping with the desired conditions.
