Embodiment Construction

[0014] In order to further disclose the technical solutions of the present invention, the following will be described in detail through examples in conjunction with the accompanying drawings:

[0015] The present invention is composed of FRP 1, ternary permeation steel pipe 2, powder 3 and steel base pipe 4. The 1.5-2.5mm cold-rolled steel plate is rolled into a round pipe, and its diameter is about 20mm larger than the inner steel base pipe. It is put into a nitriding furnace for three-way co-infiltration, that is, carbon, nitrogen, and oxygen are 3:1: 2 The ratio is dropped into the furnace (volume ratio), and the three elements are vaporized and infiltrated into the surface layer of the rolled round tube at a high temperature of 920°C. After 6-8 hours of co-infiltration, the infiltration thickness is about 0.4-0.6mm, and the processed The ternary co-infiltration steel pipe is set on the steel base pipe, and the space is welded with a support to form an annular space between...

Abstract

This invention relates to the anti-theft oil steel multiple tubes, which is composed of the glass wool, the ternary co-soak steel pipe, the Taiherd soil and the steel pipe, the character of which is that the ternary co-soak is arranged outside of the steel pipe, and they joint with the support, and the Taiherd soil plasm is primed in the annulus space between the tubes, and a layer of the glass wools is arranged at the outside of the ternary co-soak steel pipe. This invention solves the problem that the former anti-theft pipe had, and prevents the oil field and the oil gas sources from losing.

Description

1. Technical field [0001] The invention relates to a special anti-theft oil and gas-water pipeline used in a petrochemical system, in particular to an anti-theft oil steel base composite pipe. 2. Background technology [0002] At present, the oil and gas gathering and transportation process of the oil field is often destroyed by criminals, which seriously affects the normal production of the oil field and causes the oil field to suffer serious economic losses. The purpose of criminals sabotaging gathering and transportation pipelines is to steal crude oil from oilfields and sell it to some small refineries, making ill-gotten gains from it, and stealing gas for life or for factory production. One method for criminals to steal oil and gas is to drill holes on the pipeline and weld oil or gas release valves, and then use rubber or plastic pipes to put the oil into the oil stealing container and pull it away, or lead natural gas to homes or factories as a living Or the factory ...
