Problems solved by technology

[0002] In today's oil and gas gathering and transportation stations in the oil and gas industry, the gaps between the flanges of oil and gas pipelines are exposed for a long time. The side is gradually corroded, especially the metal spiral wound gasket, which will be corroded layer by layer, gradually extending to the inside of the pipeline like peeling an onion, and finally leaking, causing oil and gas leakage accidents, and even major safety accidents such as fire and explosion

Embodiment Construction

[0006] The present invention will be described in further detail below in combination with specific embodiments.

[0007] The first step is to derust the surface of the flange and its accessories (gaskets and bolts) to remove loose or raised oxide scales and attached dust to ensure that the mixture of butter and talcum powder can be used in subsequent treatments. In close contact with the surface of the flange and its accessories (gaskets and bolts) to achieve a better anti-corrosion effect.

[0008] In the second step, talcum powder and butter are blended in a container according to the ratio of 7:3 by weight. If the proportion of talcum powder is too large, it will not be firmly bonded to the flange. If the proportion of butter is too large, it will cause stickiness, which is not convenient for construction.

[0009] The third step is to fill the well-mixed talc powder and butter mixture into the gap between the flanges until the flange surface is filled. When filling the ...

Abstract

The invention relates to an anti-corrosion treatment technology of oil and gas gathering and transferring pipeline flanges in the field of the oil and natural gas industry. The technology includes the following steps that 1, the flanges and accessories (gaskets and bolts) thereof are subjected to rust removal treatment; 2, talcum powder and butter are mixed in a container according to the weight proportion of 7: 3; 3, a talcum powder and butter mixture obtained through mixing is put in seams between the flanges till the seams between the flange surfaces are full of the mixture; and 4, PVC tape firmly winds around the seam space between every two flange surfaces. By means of the anti-corrosion treatment technology of the oil and gas gathering and transferring pipeline flanges, the flanges and the accessories (the gaskets and the bolts) thereof of oil and gas gathering and transferring pipelines can be well protected from being rusted, the service life of the flanges and the accessories thereof is prolonged, oil and gas leakage is avoided, and normal production of oil and natural gas is guaranteed.

Description

technical field [0001] The invention relates to the field of petroleum and natural gas industry, in particular to an anticorrosion treatment technology for flanges of oil and gas gathering and transportation pipelines. Background technique [0002] In today's oil and gas gathering and transportation stations in the oil and gas industry, the gaps between the flanges of oil and gas pipelines are exposed for a long time. The sides are gradually corroded, especially the metal wound gaskets, which will be corroded layer by layer, gradually extending into the pipeline like peeling onions, and finally puncture leaks, causing oil and gas leakage accidents, and even major safety accidents such as fire and explosion. Contents of the invention [0003] The purpose of the present invention is to provide an anti-corrosion treatment technology for oil and gas gathering and transportation pipeline flanges, which can better protect the oil and gas gathering and transportation pipeline fla...
