Abstract
The utility model relates to a stainless lining pipe and a connecting component, consisting of a steel pipe and a pipe coupling. The thread head of the steel pipe is connected to an integrative stainless pipe orifice; a stainless lining is pasted from the inner wall of the steel pipe to the whole steel pipe; the annular gap between the stainless lining and the stainless pipe orifice is filled and sealed in a melting way by a welding line; the opposite thread heads of the two steel pipes are fit-connected by a pipe coupling screw thread; and the annular gaps between the two opposite stainless pipe orifices are connected in a sealing way by a stationary seal ring. The gap between the pipe body and the lining of the stainless inner pipe and the connecting component is sealed to prevent the inner wall of the pipe body from being corroded; and the seal ring is embedded in the coupling to prevent the thread and the coupling of the pipe body from being corroded. The utility model has the advantages of low processing cost and high economic benefit.
Description
Technical field
The utility model belongs to drilling well equipment, particularly relates to a kind of stainless steel inner lining tube and coupling assembling.
Background technology
During oil in industrial oil well pipe, sleeve field use, often have the problem that oil, sleeve pipe lost efficacy because of corrosion to take place, this is because conventional oil, sleeve pipe resistance to corrosion are poor.For preventing oil, casing corrosion, some unit uses oil, sleeve pipe and the box cupling of stainless steel material, be to have solved etching problem like this, but cost is too high, does not meet the theory of cost efficiency; Also some units uses stainless steel inner lining oil, sleeve pipe, but the space between body and liner can not be airtight, and inboard wall of tube body still can be corroded, and body screw thread and box cupling also can be corroded.
Summary of the invention
The purpose of this utility model provides a kind of stainless steel corrosion-proof lining oil, sleeve pipe and pipe nipple, is solving problem that the on-the-spot oil in oil field, sleeve pipe lost efficacy because of corrosion simultaneously, has also solved stainless steel oil, the problem that the sleeve pipe cost is high used.
Stainless steel inner lining tube of the present utility model and coupling assembling are made of steel pipe and pipe box cupling, on the silk head of steel pipe, be connected with the stainless steel mouth of pipe that combines together, inwall to full pipe at steel pipe posts stainless lining, the circumferential weld of the end face of the stainless steel lining and the stainless steel mouth of pipe is filled by sealing wire and the melting sealing, the silk head that two steel pipes are relative is cooperated by the pipe screw threads of coupler and is connected, and has friction tight joint ring sealing to connect at the annular space of two relative stainless steel pipe mouths.
As further improvement of the utility model, wherein said joint ring is made by the toughness material of anti-oily anticorrosion heatproof.
Space between its body of stainless steel inner lining tube of the present utility model and coupling assembling and liner is airtight, can prevent the inboard wall of tube body corrosion; Box cupling is embedded in the corrosion that joint ring can prevent body screw thread and box cupling, and processing charges is low, the economic benefit height.
Description of drawings
Figure of description is the structural representation of stainless steel inner lining tube of the present utility model and coupling assembling.
