Problems solved by technology

[0003] The solubility value of the existing oil delivery hose is difficult to meet the requirements of oil transportation during liquid cargo replenishment. Moreover, the existing hose has poor bending performance and is easy to discount, resulting in a large loss of fluid resistance; and the existing oil delivery hose is resistant to Poor abrasiveness, easy to damage; poor elasticity of the pipe body, poor sealing when connected with the pipe joint; low bearing strength, that is, low working pressure; poor aging resistance

Embodiment Construction

[0045] Combine below figure 1 The preparation method of the present invention is specifically described.

[0046] In this method, when preparing the oil pipeline, the mandrel is firstly prepared, and the mandrel is used for winding the rubber hose thereon. Before preparing the hose, the mandrel should be cleaned.

[0047] Then prepare the Le Ruigu 1808 release agent, stir the release agent evenly until it becomes a milky white liquid, and coat a layer of prepared Le Ruigu 1808 release agent on the mandrel. The function of the release agent is to wait until the subsequent rubber hose is prepared and shaped, and the mandrel can be taken out of the rubber hose smoothly. Due to the multiple high-temperature processes involved in the preparation of the rubber hose, if no release agent is applied, the subsequent rubber hose will adhere to the mandrel after molding and cannot be taken out.

[0048] Next, wind the first inner film on the outer surface of the mandrel in a first dire...

Abstract

The invention provides a preparation method of oil delivery pipe DN65. The oil pipeline prepared by the method of the invention has been verified and tested many times, and the medium resistance performance, isooctane extraction and physical properties of the inner film can all meet very high requirements. The solubility can be lower than 3%, which cannot be achieved by existing hoses for oil delivery. The first and second cover layers have very good resistance to oil, ozone and UV aging. The winding angles of the first adhesive plaster layer and the second adhesive plaster layer of the invention adopt balance angles of 54°44' and -54°44'. By adopting this special winding angle, the oil delivery pipe prepared by the present invention has very good bending performance and will not be bent due to bending. The invention adopts a uniquely designed winding method of the inner film and the adhesive cloth layer, which can not only achieve good bending performance, but also have high tensile strength, and can realize repeated bending and unfolding.

Description

technical field [0001] The invention relates to the field of oil material transportation, in particular to a method for preparing an oil transportation pipe. Background technique [0002] The implementation of replenishment at sea is a means of maritime logistics support that is often required for maritime operations. In the process of refueling at sea, oil hoses must be used instead of hard metal pipes like on land. Therefore, it is very important to have oil hoses with good performance. The performance of the hose determines the type of replenishment, the rate of replenishment and the quality of the replenishment liquid cargo. [0003] The solubility value of the existing oil delivery hose is difficult to meet the requirements of oil transportation during liquid cargo replenishment. Moreover, the existing hose has poor bending performance and is easy to discount, resulting in a large loss of fluid resistance; and the existing oil delivery hose is resistant to Poor abrasi...
