Description
Technical field
The utility model relates to a kind of submerged pipeline accessory, particularly about a kind of bending intensive being applicable to the static flexible pipe in ocean.
Background technique
21st century is the New Times developing ocean, and the marine petroleum development technology of China, just in develop rapidly, increases greatly to the demand of the petroleum pipeline of ocean.Current submarine pipeline is divided into two classes, steel pipe and flexible hose, and relative to steel pipe, flexible hose has designability, corrosion-resistant, flexible, easily lays, recyclable, develops more economical, is more applicable for the features such as ocean environment.Flexible pipe is the most outstanding is bending flexible, and flexible pipe can bear larger bending deflection, in marginal oil field, adopt flexible pipe, and due to easy laying, recyclable, the duration is short, can significantly reduce engineering construction and operation cost.Due to the advantage of above-mentioned flexible pipe, progressively apply at the standpipe of China and marginal oil field.Due to the restriction (bearing power of equipment and the size in space) in equipment and space in the production process of flexible pipe, a flexible pipe can not be totally continuous, a link will be there is: joint between 1 ~ 2km, joint builds epoxy resin by steel components to make, the rigidity of joint is equal to metal steel part substantially, and flexible hose is entwined by nonmetal extrusion molding and metal steel wire, it is flexible, and rigidity is low.Like this at joint and hose body joint, just there is a rigidity saltation zone, if be subject to excessive load or repeatedly bending, the little flexible pipe of rigidity will be damaged at this saltation zone, thus it is complete to destroy hose construction, causes the inefficacy of flexible pipe entirety.
Model utility content
Main purpose of the present utility model is to provide one and adds the static hose bending intensive in compact form ocean, its agent structure is made up of polyurethane elastomer and steel structure fixed block, PU body is generally polyurethane elastomer material, its good toughness, durable, and can be good at adapting to seabed operating mode.The two major features of polyurethane is that Young's modulus is low and elongation at break is high, can play well flexible and toughness; Steel structure fixed block needs directly to contact with seawater for a long time, so need to carry out anticorrosion consideration to steel beam column.By the bending stiffening device that two panels half-watt formula PU body and pieces steel beam column form, fixing with joint and body, can transfer with in installation process at flexible pipe, by self self-stiffness of bending stiffening device, the effect that rigidity is excessive is played in rigid joint and flexible pipe body, thus prevent overbending from causing the inefficacy of flexible pipe, effectively protect hose body and joint, avoid because excessive hose bends the destruction of causing, avoid owing to destroying the making of again cutting flexible pipe and joint simultaneously, lower construction cost, reduction of erection time, and reduce Attention problems risk.
The purpose of this utility model is realized by following technological scheme:
Add the static hose bending intensive in compact form ocean, comprise polyurethane elastomer, steel beam column, it is characterized in that described polyurethane elastomer is made up of two panels half-watt formula PU body, described half-watt formula PU body is cone section structure, inside is provided with groove, and described inside grooves is provided with steel beam column described in pieces, and described steel beam column main body is the fan-shaped cambered surface of steel band, main body two ends are set to flat segments, and form semi-circular cuff structure of putting more energy into.
Described steel beam column coordinates described half-watt formula PU body to be anchored on outside joint and hose body by half-watt formula PU body by clamping bolt.
Described steel beam column selection is super-duplex stainless steel and equivalent material, or carbon steel material, and according to described carbon steel material, the joint corrosion protection anode protective system need docked with bending intensive is connected by wire.
The beneficial effects of the utility model: the bending stiffening device formed by two panels half-watt formula PU body and pieces steel beam column, fixing with joint and body, can transfer with in installation process at flexible pipe, by self self-stiffness of bending stiffening device, the effect that rigidity is excessive is played in rigid joint and flexible pipe body, thus prevent overbending from causing the inefficacy of flexible pipe, effectively protect hose body and joint, avoid because excessive hose bends the destruction of causing, avoid owing to destroying the making of again cutting flexible pipe and joint simultaneously, lower construction cost, reduction of erection time, and reduce Attention problems risk.
