Abstract
The utility model provides a hose flange protector, includes the flange protector unit of two symmetries, and every flange protector unit comprises middle part gentle section and both ends changeover portion. The interior of the gentle section is provided with two protruding structures along the wall surface, and the protruding structures are used as inner interlayers and are tightly attached to a pair of flanges of the connecting hose. And bolt holes are formed in the transition section, and after bolts penetrate through the bolt holes in the two symmetrical protector units, gaskets and nuts are matched at two ends and screwed down. When the oil pipe joint is used, the two units are attached together to wrap a pair of flanges of two connected oil pipes and a part of oil pipe connected with the flanges respectively. The oil pipe flange can be effectively protected, the external profile is smooth and continuous, the oil pipe is convenient to move, and the oil pipe flange is not easy to be blocked by obstacles; the protector is made of polyurethane materials, has the characteristics of impact resistance, wear resistance and ultraviolet radiation, and can not affect the use and the function after being contacted with seawater for a long time; and the installation is simple, and the removal is convenient.
Description
Technical Field
The invention relates to a hose flange protector, in particular to an oil delivery hose flange protector for the marine oil and gas industry.
Background
The oil delivery hose establishes an important communication pipeline between the floating storage tanker (FPSO), the offshore oil and gas platform and the Shuttle Tanker (ST), and the shuttle tanker is used for transporting crude oil produced by the floating storage tanker and the offshore oil and gas platform outwards or transporting finished oil to the floating storage tanker and the offshore oil and gas platform as daily consumption.
In order to achieve the required overall length, the oil hose needs to be connected by bolted flanges. The flange can generate a bulge, and in field operation engineering, when the oil pipe is dragged, the bulge part is contacted with other structures, so that obstruction is easily generated, collision is caused, and the difficulty in dragging the oil pipe is caused.
Disclosure of Invention
The main purpose of the present invention is to overcome the above mentioned disadvantages of the prior art, and to prevent obstacles from occurring during mooring and operation in the marine oil and gas industry, the flange protector is fixed at the flange connection, so that the external profile of the outlet oil pipe is smooth and continuous.
The purpose of the invention is realized by the following technical scheme:
the utility model provides a hose flange protector, includes the flange protector unit 2 of two symmetries, and every flange protector unit 2 comprises middle part gentle section 4 and both ends changeover portion 3, and two changeover portions 3 are located 4 both sides of gentle section, form a continuum.
The interior of the gentle section 4 is provided with two protruding structures along the wall surface, and the protruding structures are used as an inner interlayer 5, and the inner interlayer 5 is used for being tightly attached to a pair of flanges of a connecting hose to play a role in fixing. The transition section 3 on be equipped with bolt hole 6, the bolt hole 6 position that is equipped with on the flange protector unit 2 of two symmetries corresponds, a long bolt passes behind the bolt hole on the protector unit 2 of two symmetries, gasket and nut are joined in marriage at both ends and screw up.
When the oil hose external diameter is D, 4 external diameters of gentle sections of flange protector are 2D, 4 length 0.8D of gentle section, and 3 length of changeover portion are 1.5D.
During installation, two flange protector units 2 are attached together, the gentle section 4 wraps up a pair of flanges of two oil pipe junctions respectively, and the transition sections 3 at both ends wrap up the oil pipe connected with the flange respectively, and then are fastened by bolts to form a whole.
When in manufacture: manufacturing a protector mold according to the sizes of the flanges and the hose, heating an oven to be completely cured after casting molding to achieve the design performance, drilling according to the design position, performing simulated assembly in a factory, fixing the two units by penetrating bolts after the two units are attached, wrapping a pair of flanges of two connected oil pipes and a part of oil pipes connected with the respective flanges in field practical application, and then fixing by penetrating the bolts.
The invention has the beneficial effects that: by adopting the technology, the external profile is smooth and continuous, the oil pipe is convenient to move, and the oil pipe is not easy to be blocked by obstacles; the protector is made of polyurethane materials, has the characteristics of impact resistance, wear resistance and ultraviolet radiation, and can not affect the use and the function after being contacted with seawater for a long time; and the installation is simple, and the removal is convenient.

Fig. 2 is a schematic structural diagram of a symmetrical single unit according to the present invention.
FIG. 3 is a schematic view of a hose flange connection without a flange protector.
FIG. 4 is a schematic view of a hose flange connection using a flange protector.
In the figure: 1 flange protector, 2 flange protector units, 3 transition sections, 4 gentle sections, 5 interior interlayers, 6 bolt holes.
Detailed Description
The present invention is further illustrated by the following specific examples.
As shown in fig. 1 and 2, a hose flange protector comprises two symmetrical flange protector units 2, each flange protector unit 2 consists of a middle gentle section 4 and two end transition sections 3, and the two transition sections 3 are positioned on two sides of the gentle section 2 to form a continuum. The inside wall of following of gentle section 4 is equipped with two protruding structures, and as interior interlayer 5, interior interlayer 5 is used for closely laminating with a pair of flange of coupling hose, plays the fixed action. Be equipped with bolt hole 6 on the changeover portion 3, the bolt hole 6 position that is equipped with on the flange protector unit 2 of two symmetries corresponds, and a stay bolt passes behind the bolt hole on two symmetrical protector units 2, and gasket and nut are joined in marriage at both ends and screw up. When the outer diameter of the oil hose is 200mm, the outer diameter of the gentle section of the flange protector is 400mm, the length of the gentle section is 160mm, and the length of the transition section is 300 mm.
During installation, two flange protector units 2 are attached together, the gentle section 4 wraps up a pair of flanges of two oil pipe junctions respectively, and the transition sections 3 at both ends wrap up the oil pipe connected with the flange respectively, and then are fastened by bolts to form a whole.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent variations and modifications made to the above embodiment according to the technical spirit of the present invention still fall within the scope of the technical solution of the present invention.
