Welded 5CT K55 Tubing

Programming interface 5CT K55 oilfield pipe packaging channel is fundamentally the same as J55, there is no noteworthy contrast in the synthetic structure and yield quality, anyway a definitive rigidity of K55 is higher than J55 steel, K55/J55 are 655MPa and 517MPa separately. K55 has better mechanical and warm weakness opposition and break obstruction than K55. For a warm generation well, the substantial divider K55 packaging is fitting rather than J55 packaging. The previous has a superior warm weakness obstruction property than the last mentioned. In present deals, the selling cost of postulations two sorts is commonly kept the equivalent, their application is fundamentally the same as. In the oil boring, K55 API 5CT packaging or tubing is a generally regular sort.

Programming interface 5CT K55 and J55 oilfield oil packaging channel is very like J55, there is no impressive refinement inside the compound piece and yield quality, howeverhigher than J55 steel pipe.

Programming interface 5CT K55 Casing Tubing is an API 5CT Oil Casing Pipe and basically utilized for oil well penetrating. We make API 5CT K55 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 API 5CT oil packaging funnel can be isolated into ten sorts, including H-40, J-55, K-55, N-80, C-75, L-80, C-90, C-95, P-110 and Q-125. We supply the packaging channel and API 5CT K55 Casing Tubing went with string and coupling, or we offer our item as per the accompanying structures for alternative. On the off chance that you are keen on API 5CT K55 Casing Tubing, we will supply you with the best cost dependent on the most astounding quality

API 5CT K55 Casing Tubing Features

  • API 5CT K55 Casing Tubing is offered with a free length range from 8m to 13m on basis of the SY/T6194-96 norm. However, it is also available no less than 6m length and its quantity should be no more than 20%.
  • Deformations which mentioned above are not allowed to appear on the outer surface of API 5CT K55 Casing Tubing coupling.
  • Any deformation such as hairline, separation, crease, crack or scab is not acceptable on both inner and outer surfaces of the product. All these defects should be completely removed and the removed depth must not exceed 12.5% of nominal wall thickness.
  • The surface of thread of coupling and API 5CT K55 Casing Tubing should be smooth without any burr, tear or other defects that may have a negative impact on the strength and close connection.

It's important for oil and gas operators to protect their production well casings from corrosion with cathodic protection & API 5CT OilField Tubing primarily serves to transfer oil and gases.
