The utility model has extensive application prospect in the industries such as petrochemical complex, medicine, food and the like, and can guarantee not only the intensity of use of the spherical tank but also the special requirement thereof on corrosion resistance. Moreover, the utility model has the advantages of lower equipment material cost, prolongation of equipment service life and reduction of construction cost.

Description

不锈钢复合板球罐 Tank stainless steel clad plate

技术领域 FIELD

本实用新型属于球罐,具体涉及一种不锈钢复合板球罐。 The present invention belongs to the tank, particularly to a composite steel plate Tank. 背景技术 Background technique

球罐以其结构形式合理、使用压力高、节约材料,广泛使用于城市的公用民用行业(城市天然气、液化石油气)、冶金行业(氧气、氮气、氩气等)、化工行业(许多的易燃、易爆、有毒的化工产品)等行业,现有的球罐的球壳板通常都是单层材料(碳钢,低合金钢,调质高强钢等),其使用都存在一定的局限性。 Tank its reasonable structure, high pressure, saving material, widely used in urban public civilian sectors (urban natural gas, liquefied petroleum gas), metallurgical industry (oxygen, nitrogen, argon, etc.), chemical industry (many easy fuel, explosive, toxic chemicals), etc., a conventional spherical tank petal are usually single layer of material (carbon steel, low alloy steel, hardened and tempered steel, etc.), there are some which use limitations sex. 发明内容 SUMMARY

本实用新型为了解决现有技术中球罐腐蚀性和强度不能很好地满足使用要求的问题,提供了一种不锈钢复合板球罐。 The present invention is to solve the prior art Spherical resistance and strength can not meet the demands of the problem, there is provided a composite steel plate Tank.

本实用新型采用如下的技术方案实现:不锈钢复合板球罐,包括球壳板制成的球形罐体,罐体下部支撑于支柱上,相邻的支柱通过拉杆连接,罐体上下两端设置球附件,其特征在于所述的球壳板由外侧的低合金钢层和内侧的不锈钢层构成。 The present invention uses the following technical solution: stainless steel clad plate tank, comprising a spherical body made of a spherical shell plate, the tank bottom is supported on struts, adjacent struts connected by a tie rod, the ball body is provided upper and lower ends Annex, wherein said spherical shell plate made of stainless steel and an inner layer of low-alloy steel layer to the outside.

本实用新型与现有技术具有如下有益效果: The present invention and the prior art has the following advantages:

1、 与碳钢球罐相比,采用爆炸不锈钢复合板可以根据石化设备内的介质腐蚀性的强弱,通过选用合适的不锈钢作为复层,达到延长设备使用寿命,减少维修次数的目的,从而具有经济性。 1, compared with carbon steel tank, stainless steel composite panels using explosive strength of the medium according to the corrosive petrochemical equipment, by appropriate choice of stainless steel as the cladding layer, to prolong the life of the device, the purpose of reducing maintenance times, thus economical.

2、 与不锈钢球罐相比,采用爆炸不锈钢复合板可以根据石化设备的不同强度要求,选择合适的钢板作基材,从而节约价格昂贵的不锈钢,达到降低造价的目的。 2, compared with the stainless steel tank, stainless steel composite panels using explosive strength requirements according to different petrochemical equipment, selecting the right plate as a substrate, thereby saving expensive stainless steel, achieve lower cost.

3、与碳钢+衬里不锈钢球罐相比,由于爆炸不锈钢复合板界面是全面积 3, as compared with stainless steel liner + tank, the explosion was stainless steel clad plate is the total area of ​​the interface

的冶金结合且结合强度高,可在设备内件的连接...[::简化制造工艺,同时减少设备的维修次数。 Metallurgical bonding and high bonding strength can be connected to the inner member in the device ... [:: simplifying the manufacturing process, while reducing the number of equipment maintenance.

本实用新型在石油化工、医药、食品行业等有着广阔的应用前景,既能保证球罐的使用强度,又能保证球罐对耐腐蚀性的特殊要求,也大大降低了设备的材料成本,提高了设备的使用寿命,降低了工程造价。 The present invention has broad application prospects in petrochemical, pharmaceutical, food industry, both to ensure the use of the strength of spherical tank, spherical tank can guarantee the corrosion resistance of special requirements, but also greatly reduces the material cost of the equipment, improve the life of the equipment, reducing the project cost. 附图说明 BRIEF DESCRIPTION
