Heat resistanceIn intermittent use below 1600 degrees and continuous use below 1700 degrees, 316 stainless steel has good oxidation resistance. In the range of 800-1575 degrees, it is best not to continuously act on 316 stainless steel, but when 316 stainless steel is continuously used outside this...[详细]
304 is a versatile stainless steel, which is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability).301 stainless steel shows obvious work hardening during deformation, and is used in various occasions requiring higher strength.302s...[详细]
In layman's terms, stainless steel is steel that is not easy to rust. In fact, some stainless steels have both rust resistance and acid resistance (corrosion resistance). The rust resistance and corrosion resistance of stainless steel are due to the formation of a chromium-rich oxide film (passi...[详细]

Stainless steel material is a kind of material with brightness close to mirror surface, tough and cold touch. It is a relatively avant-garde decorative material with excellent corrosion resistance, formability, compatibility and toughness. It is used in heavy industry and light industry. , Daily nec...[详细]
Card sleeve ball valves are mainly used for long-distance pipeline transportation of oil and natural gas and city gas pipeline systems. Due to its unique characteristics, the long-distance pipeline valve fully considers its ability to withstand pipeline stress, safety, weather resistance and long-te...[详细]
Analysis of common thread size:A series of dimensions are required for the machining of common thread by CNC lathe. The calculation and analysis of the dimensions required for the machining ofcommon threadmainly include the following two aspects:1. Workpiece diameter before thread processing:C...[详细]
叶轮与泵壳成偏心,泵壳内充一定量的水,叶轮旋转使水形成水环。相邻叶片(如图中红色叶片)旋转时,与水环形成的空间(气室)变大即进气,空气(气室)逐渐变小,即空气被压缩。多组相邻叶片,即多组往复压缩。结构紧凑、工作平衡可靠和流量均匀,所以化工生产中多用来输送或抽吸易燃、易爆和有腐蚀性的气体。水环式真空泵...[详细]
1、不允许在衬氟蝶阀上做任何高温焊接工作,以免造成衬里层的永久损害。 2、经维修后的衬氟阀门在使用前要按相关标准测试合格方可安装。 3、衬氟蝶阀与管路连接时,一般并不再单独使用垫片,但与异种材料(金属面等)法兰面相接时,应采用适当垫片,以保护PT...[详细]
