小口径方管在哪些地方可以使用到?

发布时间:2019-05-10人气:30
烟台方管市场或以盘整运行为主厂家心态偏空…方管本周烟台方管市场价格拉涨,成交一般。回顾本周,周初期货市场强势拉涨,本地现货市场跟涨,成交尚可,中期期货冲高回落,本地市场紧跟期货回调,而后市场暂稳,出货一般。现烟台方管主流价格在3780元/吨。成交方面,据了解本周烟台市场虽然价格方面有所拉涨,但实际市场需求面改善并不多,且方管厂家手上库存…

小口径方管用作炼钢吹氧用管,冶炼吹氧用钢管一般用焊接钢管,规格由3/8寸-2寸八种。用或Q195-Q235钢带制成。为防蚀,有的进行渗铝处理。是在S系列产品基础上研制而成,天津吹氧管,结合了当前电弧炉炼钢的实际需要,耐火度高、消耗量少、操作方便等特点。电弧炉炼钢中输送氧气或其它气体,在电弧炉内熔化并精炼钢铁。

Small caliber square pipe is used as oxygen blowing pipe in steelmaking. Welded steel pipe is generally used for oxygen blowing pipe in steelmaking. The specifications range from 3/8 inch to 2 inch. Made of or Q195-Q235 steel strip. In order to prevent corrosion, some are aluminized. It is developed on the basis of S series products. Tianjin oxygen blowing pipe combines the actual needs of electric arc furnace steelmaking. It has the characteristics of high refractory, low consumption and easy operation. In electric arc furnace steelmaking, oxygen or other gases are transported to melt and refine steel in the electric arc furnace. 小口径方管冶炼吹氧用钢管按焊接方法不同可分为电弧方管、高频或低频电阻方管。电焊钢管用于石油钻采和机械制造业等,可用作水煤气管等,大口径直缝方管用于高压油气输送。吹氧管厂家生产的扩口吹氧管,强度一般比直缝方管高,能用较窄的坯料生产管径较大的方管,还可以用同样宽度的坯料生产管径不同的方管。但是与相同长度的直缝管相比,焊缝长度增加30~100%,而且生产速度较低。因此,较小口径的方管大都采用小口径方管,大口径方管则大多采用螺旋焊。

Small caliber square pipe for oxygen blowing can be divided into arc square pipe, high frequency resistance square pipe or low frequency resistance square pipe according to different welding methods. Welded steel pipes are used in oil drilling and mechanical manufacturing, water gas pipes, etc. Large diameter straight seam square pipes are used for high pressure oil and gas transmission. Oxygen blowing tube manufacturer's enlarged oxygen blowing tube has higher strength than straight slotted square tube. It can produce square tube with bigger diameter with narrower blank, and can also produce tube with different diameter with the same width blank. However, compared with the straight seam pipe of the same length, the length of the weld increases by 30-100%, and the production speed is lower. Therefore, the small diameter square pipe is mostly used, while the large diameter square pipe is mostly spiral welded.
