什么是CGA接头?什么是DISS接头?韩国HANSUN S-LOK管阀件
使用高纯氨的时候,钢瓶、管道、阀门都需要认真考虑,而其中钢瓶阀门与管道连接的接头(通常就是所谓的CGA660和DISS720)比较特殊,相关的部件都已经有较为成熟的标准和产品,但是相关的说明比较混乱,让人看完了往往还是一头雾水,在这儿我们尽可能做一些浅显的说明,整理一下头绪。
什么是CGA接头?
CGA是Compressed Gas Association的简称,字面的意思为“压缩气体协会”,实际上是指美国压缩气体协会,这个协会制定了不同种类的特殊气体的接头标准(特别是针对钢瓶阀门的连接接头),在这个标准中,针对各种特气使用了不相同的数字编号来区分接头,比如660针对的是氨气(Ammonia),在习惯上,CGA660就是针对氨气的接头。很多人根本不知道(也无需知道)美国压缩气体协会,就像我不知道中国压缩气体协会一样(你知道有中国压缩气体协会吗?或者你知道中国压缩气体协会制定的某个标准吗?)美国压缩气体协会还在不断地修改接头的标准,比如到2002年已经出版了标准的第10版。在新的标准中,有些原有的编号会被移去,而新的编号也会加进来。特气接头使用的实际情况比上面说的还要更复杂一些,不同的气体有可能使用同一个编号,比如,BCl3和NH3都可以使用CGA660,而同一种气体有时也可以使用不同编号的接头,比如,CGA705和CGA660都可用于氨气。这部分原因可能来自标准的不断修改和优化,根据新旧标准制造的接头可能共同存在于市场上。什么是DISS接头?
什么是DISS接头?
DISS是Diameter Index Safety System的简称,字面的意思为“直径指数安全系统”,估计很少人知道DISS的真实含义(实际上也无需知道)。它实际上也是CGA(美国压缩气体协会)制定的针对不同特气的接头标准,是CGA制定的比较新的标准,而且也是使用不同的数字来针对不同的气体,比如720对应的是氨气,DISS720也是针对氨气的接头,完整地讲应该称为CGA DISS 720,但是人们往往比较偷懒,通常只说DISS720,有些情况下,也有称为CGA 720的。
韩线工程有限公司于2012年设立, 主要生产S-LOK品牌接头阀门, 拥有 世界顶尖的生产工艺和设备, 拥有 ABS/ API/ BV /DNV/ CCS/NK等多项国际认证 并每年保持更新。我们热处理设备以天然气 为燃料, 因此对材料进行热处理加工时不但 热量分布均匀, 且能很好地控制其升、降温曲线。 这样不仅有利于材料金属晶格的有序排列、 最大限度的消除缺陷, 并能使碳粒子充分 细化和排列均匀。经该设备处理加工后的材 料不仅具有良好的抗疲劳性, 也大大提升了 其抗拉强度。在产品制造后端, 我们采 用了锻打和压实工艺, 从而使产品提高了直径 —压力比, 具有了更高的耐高温高压、抗震颤性, 因而能够保证产品充分的稳定性和使用寿命。 在产品检测阶段, 我们对每一个出厂的产品进行检测, 并根据客户要求添加检测项目, 努力使每一个出厂的 产品符合客户的要求。
