Definitions
- the present invention relates to piping, and more particularly to a piping for sending a slurry and steam containing the slurry.
- HPAL High Pressure Acid Leach
- the nickel oxide ore was first classified and obtained by classification.
- a nickel oxide ore having a predetermined size is repulped into an ore slurry (hereinafter, also simply referred to as “slurry”), and the slurry is heated and pressurized stepwise and transferred to an autoclave.
- an acid such as sulfuric acid is added, and nickel or the like is leached from the nickel oxide ore slurry.
- the leached slurry is cooled and stepped down in stages and sent to the next step.
- the process of raising the temperature and increasing the pressure of the slurry as described above is a process using high-temperature waste steam generated in the HPAL process.
- the slurry to be treated is charged into a pressure vessel (hereinafter referred to as “heater tank”) by a centrifugal pump, heated by the steam blown into the heater tank, and transferred to the next heater tank.
- the temperature is raised to a desired temperature.
- the outer diameter of the suction pipe of the centrifugal pump is larger than the outer diameter of the discharge pipe. Therefore, in order to arrange the centrifugal pumps of the same type in series, pipes having different pipe diameters at one end and pipe diameters at the other end, so-called different diameter pipes, are used for connection between the centrifugal pumps to be connected in series.
- waste steam from a decompression tank provided in the next step of the autoclave is used, and the slurry is made acidic by acid such as sulfuric acid contained in the waste steam. Therefore, there is a problem that not only wear due to transfer of the slurry at high pressure but also corrosion due to transfer of the high temperature and acidic slurry proceeds.
- waste steam used in the process of raising the temperature and increasing the pressure of the slurry is sent from the decompression tank to the heater tank using piping, but the waste steam that has passed through the autoclave is used.
- Acid steam or steam containing an acidic slurry is used. Therefore, similar to the problem that occurs when the slurry is transferred, the piping from the decompression tank to the heater tank is rapidly worn or corroded when the steam is sent.
- piping is also used when transferring acidic slurry to a treatment tank for cooling and lowering the temperature of the slurry that is provided next to the autoclave.

- a plate tension sometimes referred to as a “sacrificial plate”
- a buffer material to increase the shock resistance
- a method of attaching the wear resistant material by overlay welding or thermal spraying is used.
- the method of attaching the sacrificial plate to the pipe is a method of attaching a sacrificial plate having the same material and thickness as the pipe to a specific location in the pipe by welding. Since the pipe for transferring the acidic slurry under high temperature and high pressure needs to have corrosion resistance, an expensive material such as titanium is used for the sacrificial plate. Therefore, although this method is easy as construction, the cost becomes high. In addition, materials such as titanium have corrosion resistance but are not wear-resistant, so even if the plate thickness is increased to extend the service life, they will be consumed in several months, requiring re-repair or replacement. End up. For this reason, the method of attaching the sacrificial plate has a limited effect, and its implementation is accompanied by an increase in work cost.
- the buffer material a rubber material is mainly represented.
- the temperature of the slurry is raised to about 100 ° C. to 200 ° C., so that a buffer material made of a rubber-based material having no heat resistance is sent to the slurry or steam containing the slurry. It is difficult to apply to other pipes.

Abstract
Description
配管に犠牲板を取り付ける方法は、配管と同じ材質で厚みを持つ犠牲板を配管内の特定の箇所に溶接で取り付ける方法である。高温高圧下において酸性スラリーを移送する配管には、耐腐食性が必要であるため、その犠牲板にはチタン等の高価な材料を使用している。したがって、この方法は、施工としては容易であるがコストが高くなってしまう。また、チタン等の材料は、耐腐食性はあるものの耐摩耗性がないため、寿命を延ばすべく板厚を増加しても数ヶ月で消耗してしまい、再補修もしくは取替が必要となってしまう。このことから、犠牲板を取り付ける方法は、得られる効果が限定的であり、しかもその実施には作業コストの上昇を伴う。
緩衝材としては、主にゴム系材料に代表される。ところが、HPALプロセスにおけるスラリーを昇温する処理では、そのスラリーを100℃~200℃程度まで昇温するため、耐熱性を持たないゴム系材料からなる緩衝材をスラリーやスラリーを含む蒸気を送るための配管へ適用することは困難である。
流体摩耗に対する耐摩耗材料に関しては、硬化肉盛や高分子ポリエチレンに見られるように多くの材料が使用されているが、これらの一般的な耐摩耗材料は、常温下の使用に限定されることや酸性雰囲気では脆弱である。そのため、高温高圧下の酸性スラリーを移送する条件に合致するものとしては、セラミック等の限定された材料となる。セラミックが使われた配管としてはセラミックライニング鋼管が多く使用されているが、このセラミックライニング鋼管は、セラミックの耐摩耗性に主眼を置いているため、配管の母材となる部分には炭素鋼を用いている。このように、セラミックライニング鋼管においても、母材として炭素鋼を使用しているため、ライニングであるセラミックに亀裂等の欠陥が生じた場合には、酸性スラリーが耐腐食性に乏しい炭素鋼を短時間で腐食してしまい、その結果として配管に孔が開いてしまう。
本実施の形態に係る配管は、スラリー、又はスラリーを含む蒸気を送るための配管である。この配管は、例えば、ニッケル酸化鉱石のスラリーに対して高温、高圧下で硫酸等によりニッケルを浸出させるHPALプロセスにおけるプラントに用いることができる。より具体的には、ニッケル酸化鉱石のスラリーを段階的に昇温、昇圧して、オートクレーブに移送するための移送配管として用いることができ、この配管においては、スラリーのみならず、そのスラリーを含む蒸気も移送される。
図2は、本実施の形態に係る配管の構成の一例を示した断面図である。図2に示すように、配管10は、円筒形の母材11によって管状に形成されている。そして、この配管10は、円筒形の母材11と、その母材11の内径よりも小さい外径を有するライニング材12と、母材11とライニング材12との隙間を埋める充填材13とから構成される。
母材11は、円筒形の材料からなり、管状構造である配管10の母体を構成する。母材11は、耐腐食性を有する材料から構成され、好ましくは、ステンレス、ニッケル又はニッケル合金、チタン又はチタン合金、コバルト又はコバルト合金等から構成される。
ライニング材12は、母材11と同様に円筒形の材料からなり、母材11の内径よりも小さい外径を有して母材11の内側に配置される。このライニング材12は、断面視したときのライニング材層12sを構成するものであり、つまり、配管10の管状を構成する母材層11s/充填材層13s/ライニング材層12sの3層構造20において、最も内側に位置する内層となるものである。
充填材13は、母材11とライニング材12との隙間を埋めて接着させるためのものであり、断面視したときの母材層11sとライニング材層12sとの間に位置する中間層である充填材層13sを構成する。
本実施の形態に係る配管10としては、特に限定されないが、図2の断面模式図に示すように、スラリーが移送される上流側と下流側とで外径の異なる配管、いわゆる異径配管とすることができる。異径配管は、その外径が変化する部分(図2中の「P」で示す部分)を有している。
