Experimental device for simulating corrosion in crude oil pipeline

Abstract

The invention provides an experimental device for simulating corrosion in a crude oil pipeline. The experimental device comprises a temperature-control water bath tank, a corrosion experimental tank, a condensate water tank, a condensate water tube, a water storage tank, an oil conveying tube and an oil storage tank, wherein the temperature-control water bath tank and the corrosion experimental tank are of structures without top covers; the corrosion experimental tank is positioned inside the temperature-control water bath tank; the upper part, which is positioned in the temperature-control water bath tank and the corrosion experimental tank, of the condensate water tank forms the top cover; a circulating loop is formed between the condensate water tank and the water storage tank through the condensate water tube, and a circulating water pump is arranged on the condensate water tube; a circulating loop is formed between the corrosion experimental tank and the oil storage tank through the oil conveying tube, and a circulating oil conveying pump is arranged on the oil conveying tube; a storage rack is arranged at the inner lower part of the tank body of the corrosion experimental tank, and a plurality of sheet suspenders are arranged on the storage rack; a plurality of first corrosion clamping slots are formed in the bottom of the condensate water tank; corrosion test pieces which are matched are placed in the first corrosion clamping slots and the sheet suspenders. The experimental device is simple in structure, convenient to operate and strong in practicability, and the corrosion state in the pipeline can be evaluated in most of laboratories.

Description

technical field [0001] The invention belongs to the field of crude oil pipeline internal corrosion experimental equipment, in particular to a crude oil pipeline internal corrosion simulation experimental device. Background technique [0002] Corrosion has always been an important cause of pipeline damage and failure. The loss caused by corrosion is very serious. In addition to the economic loss caused by equipment maintenance, pipeline stoppage, reduction in transmission efficiency, raw material and energy loss, etc., there are also environmental pollution and personal safety problems caused by pipeline leakage and explosion caused by corrosion. In particular, top corrosion and flow corrosion in pipelines have attracted the attention of enterprises and researchers because of their many influencing factors and complicated detection and maintenance. [0003] Top corrosion refers to the generation of condensed water at the top of the pipeline when water vapor passes through th...
