Abstract
The invention provides a high seal and corrosion-resistant seabed conveying pipeline connecting device, which includes an upper flange, a lower flange, bolts, an upper pipe, a lower pipe, a seal ring I, and a seal ring II, and is characterized in that the upper flange is connected with the upper pipe; the lower flange is connected with the lower pipe; the upper flange is concave, and is provided with an upper flange connecting surface and an upper flange concave surface; the lower flange is convex, and is provided with a lower flange connecting surface and a lower flange convex surface; the seal ring I and the seal ring II are placed at the joint of the upper flange and the lower flange; the upper flange is connected and fixed with the lower flange through the bolts; surfaces of all components are sprayed with Xylan coatings. The connecting device is firm in connection and high in seal and corrosion resistance, and guarantees the safe and stable running of a seabed oil and gas pipeline.
Description
Technical field
The present invention relates to a kind of assembling pipe joint, relate in particular to a kind of seabed conveyance conduit connection set.
Background technique
Annual all over the world have a large amount of oil gas to need transportation, with marine transportation, compares, and adopts submarine pipeline to carry the oil gas quantity delivered larger, more economical, safer.But in case it is also more difficult that pipe leakage occurs, leakage will cause waste the bad border, severe contamination ocean of ample resources, so the seabed conveyance conduit is had to very high quality requirement, especially pipeline connects.Because environments such as subsea has high pressure and corrosivity, corrosion failure pipeline, high pressure easily cause leaking, so require seabed conveyance conduit connection set to have anticorrosive property and high leak tightness.
Summary of the invention
The object of the present invention is to provide a kind of seabed conveyance conduit connection set of high-sealing corrosion-resisting erosion.
Technological scheme of the present invention is: a kind of seabed conveyance conduit connection set of high-sealing corrosion-resisting erosion, comprise upper flange, lower flange, bolt, upper pipe, lower pipe, seal ring I, seal ring II, and it is characterized in that upper flange connects upper pipe, lower flange connects lower pipe; Upper flange and lower flange all are provided with through hole and some bolts hole; Upper flange is spill, is provided with upper flange junction surface and upper flange concave surface, and the upper flange concave surface is provided with the groove I, and the upper flange junction surface is provided with the groove II; Lower flange is convex, is provided with lower flange junction surface and lower flange convex surface, and the lower flange junction surface is provided with the groove III, and the lower flange convex surface is provided with the groove IV; Upper flange and lower flange adopt some bolts to be connected and fixed, and groove I and groove IV, over against forming circular groove, are placed the seal ring I in it; Groove II and groove III, over against forming circular groove, are placed the seal ring II in it; The surface spraying of upper flange, lower flange, bolt, top tube and down tube the Xylan coating, Xylan is a kind of coating that U.S. Hua Fu company (WHITFORD) produces, Xylan is the mixture of fluoropolymer, engineering plastics and elite preservative, has superior Corrosion Protection.Seal ring I and seal ring II are made by anti-corrosive rubber.
Technique effect of the present invention is: concaveconvex structure is adopted in upper flange and lower flange joint, makes dislocation between them become flexible, and is connected firmly, and has extended the length of connecting sewing, and two corrosion resistant seal rings are set in joint, and high leak tightness so just is provided.The surface spraying of each parts the Xylan coating, make the present invention can have good anticorrosive property.For safely and steadily running, sea-bottom oil-gas pipeline provides safeguard.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Upper flange 2, lower flange 3, through hole 4, bolt hole 5, bolt 6, upper pipe 7, lower pipe 8, seal ring I 9, seal ring II 10, upper flange concave surface 11, groove I 12, upper flange junction surface 13, groove II 14, lower flange junction surface 15, groove III 16, lower flange convex surface 17, groove IV in the drawings 1.
