Problems solved by technology

[0003] However, the anti-corrosion technology of water pipelines, gas pipelines and chemical raw material pipelines is the weakest anti-corrosion mitigation of the entire pipeline. Pipeline corrosion, perforation, and leakage have brought serious losses to oil and gas fields and the country. The development of anti-corrosion technology It is directly related to the safe operation and service life of the pipeline

Abstract

The invention relates to hot melting horseshoe gum resin which is characterized by comprising the following components in percentage by weight: 30-50 percent of elastomer, 10-20 percent of asphalt, 25-40 percent of trackifing resin, 5-20 percent of plasticizer, 5-10 percent of filler and 0.2-0.5 percent of antioxidant. A product of the invention is used for corrosion protection of pipelines and has good bonding and sealing property, good low-temperature resistance, higher peel strength and stable performance.

Description

technical field [0001] The invention belongs to the technical field of hot-melt glue for pipeline anticorrosion, and in particular relates to a hot-melt horseshoe glue. Background technique [0002] With the rapid development of my country's economy, the application of engineering pipelines is becoming more and more extensive, especially in my country's gas transmission pipelines. The start of the project and the planned start of the largest gas transmission pipeline project between China and Russia in Xinjiang will set off a peak period for my country's oil and gas pipeline construction. [0003] However, the anti-corrosion technology of water pipelines, gas pipelines and chemical raw material pipelines is the weakest anti-corrosion mitigation of the entire pipeline. Pipeline corrosion, perforation, and leakage have brought serious losses to oil and gas fields and the country. The development of anti-corrosion technology It is directly related to the safe operation and serv...
