Description
Technical field
The utility model relates to a kind of micritization lass lining oil and gas pipes heating specific equipment, and particularly one can folding speciality Horizontal Heating electric furnace.
Background technology
Oil and gas pipeline is called for short oil and gas pipes, is the important component part of country of China public safety, occupies very important strategic position, be called as national great lifeline in national economy.According to reports, the existing long oil and gas pipeline of China about 10
5km, gathering line is about 3 × 10
5km, in recent years domestic will be in oil and gas pipes build peak period, to " 12 " latter stage, China's long oil and gas pipeline total length reaches 1.5 × 10
5km.
Corrosion is one of key factor affecting oil and gas pipeline reliability and work-ing life.In recent years, rapidly, pH value variable is large, delivery medium complicated component, corrodibility are strong, and abrasive wear is large, causes corrosive pipeline problem to become increasingly conspicuous for the development of recover petroleum, gas gathering and transportation and long distance pipeline construction.
Also has pipeline outer wall by a technical quality difficult problem for the considerable safety guarantee such as edatope stress corrosion crack sudden accident and the integrally-built distortion of pipeline.
Qingdao Pipeline Leak, maintenance is exploded suddenly.President Xi Jinping sends great instruction: " intensified safety production measure, firmly stops this type of accident ".
The pipeline that existing inhibiter technology, undercoat technology, multiple-unit tube technology are made, is added on steel pipe inner wall surface for self material depends in fact.Oil and gas pipes is in long-term conveying, because of tube wall surface oil gas medium knot dirt, need regular flush clean, oil gas waste is large, transport efficiency is low, and anticorrosive, wear resistance is poor, resistance to mechanical intensity is low, and the safety control such as environmental stress corrosion cracking and the distortion of pipeline one-piece construction, far can not meet the conveying in the long spool road of oil gas.
The enamel pipeline that nineteen ninety is carried to generating factory director line by colliery direct sending by research department's registration study coal grain of national most authority, well-designed and manufactured vertical electrically heated oven and Horizontal electric process furnace, also corresponding supporting automatic temperature control apparatus.
Vertical hot plate can not limit by pipeline major diameter and bit length, and pipeline burns till rear collimation and ensures, but the enamel for glassed steel layer of inner-walls of duct is flow state in high temperature (850-900 DEG C) burns till, and thin lower end, upper end is thick, and glaze layer uniformity coefficient is poor.
Horizontal Heating electric furnace, pipeline enters stove difficulty, difficulty of coming out of the stove, and because pipeline support buck is fire stop in process furnace, overall enamel for glassed steel layer is heated uneven, causes the of poor quality of the enamel for glassed steel layer after burning till; Pipeline cause in long-time heat several times pipeline one-piece construction and two end flange face deflections large, security and the economic benefit of total engineering are installed in direct correlation, and do not meet existing GB GB25025-2010 (device diameters >=1000mm, minimax diameter difference≤6mm, flatness tolerance≤2mm); Also have Horizontal Heating electric furnace diameter to amplify, electric energy consumption increases; Electric furnace is fragile etc.
Apply vertical and Horizontal electric process furnace as can be seen here, because entirety is uneven compared with long pipeline heating temperature, the extremely difficult manufacture breaking through long pipeline, serious quality problems existing for its overall enamel for glassed steel layer and pipeline one-piece construction, two end flange face are out of shape.
Trial-production through time is more than a year not suitable for coal grain length line Cemented filling, terminates the research of project, has not yet to see the exploitation manufacture of large-scale lass lining pipeline over more than 20 years.
By an engineering 2000 kilometers reckoning, be 5 meters with pipeline length, then installing interface is 400,000, if pipeline length is 25m, then installs interface and can be reduced to 80,000.
By an engineering 2000 kilometers reckoning, pipeline lass lining useful area reaches 6,000,000 m
2, the enamel for glassed steel layer useful area>=89m of the glass-lined equipment technical qualification defined formulated by GB25025-2010 country
2, it is 7 that pin hole repairs number, then the pinhole number of full engineering pipeline is up to 460,000.Can affirm: the existence of everywhere needle pore defect, direct correlation gross investment is up to the security of hundreds of hundred million Renminbi superprojects project and economic benefit.
This is that to be suitable for petroleum transportation pipeline why must be large-scale long pipeline, the major cause that the quality of overall enamel for glassed steel layer must be excellent.
Therefore the innovation of hot plate, must comprehensively meet by the demand of pipework and the greatest length (diameter 1.0 ~ 1.6m of steel pipe goods, 25m can be combined as) by 2 steel-pipe weldings, manufacture different size and the excellent large-scale micritization lass lining pipeline of total quality, to reduce the installation interface between omnidistance main pipeline, be convenient to site operation, installation, thus drastically increase the quality of pipework entirety, the effect that circulates and safe operation.
