Stainless Steel J55 Tube

Programming interface 5CT J55 Casing Tubing serves to transport both unrefined petroleum and gaseous petrol from oil and gas layer to the surface pipeline subsequent to boring is finished. It can shoulder the weight created by the misuse procedure. After the external surface is covered with a defensive layer, the tubing is set apart as per the API 5CT standard and lashed with metal belt. Our oilfield tubing and J55 Tubing Material can be generally relevant to oil, development, shipbuilding, refining, aeronautics, electric power, sustenance, paper, compound industry, restorative hardware, boilers, heat exchangers, metallurgy, etc.

This oilfield tubing can be delegated NUE type and EUE type. You can discover here Seamless 5ct j55 Petroleum Casing Pipe Dimensions and Casing Wall Thickness. Determinations incorporate 1.9in(48.3mm), 2 3/8in(60.3mm), 2 7/8in(73.03mm), 3 1/2in(88.9mm), 4in(101.6mm), 4 1/2in(114.3mm) and so forth. The profundity of our item to plummet the well is fundamentally indistinguishable to that of oil packaging channel. Both mechanical property and fixing execution of this tubing are additionally required to relate with the oil packaging funnel. Oil Tubing fundamental steel grade incorporates J55, N80, C90, P110 and some others. for more subtleties check beneath Casing And Tubing Tables, Casing Grade Table, and Casing Data Tables.

Programming interface 5CT J55 Casing Tubing is an API 5CT Oil Casing Pipe and mostly utilized for oil well penetrating. We produce API 5CT J55 Casing Tubing as per the SY/T6194-96 standard, it is accessible as short string sort and long string sort provided with their couplings. As indicated by American Petroleum Institute Standard API SPEC 5CT1988 first version, the steel evaluation of Grade J55 Oil Well Drilling Casing Pipe can be partitioned into ten kinds, including H-40, N-80, J-55, C-90, K-55, C-75, L-80, C-95, Q-125 and P-110. We supply the packaging channel and API 5CT J55 Casing Tubing went with string and coupling, or we offer our item as per the accompanying structures for choice.
