Sulfinert Treated Swagelok Sample Cylinders硫钝化的取样钢瓶

• Sulfinert coating provides stable storage of sulfur and mercury at ppb levels in petroleum samples.硫钝化的涂层为采样罐提供了稳定的性能，可以储存PPB级的含硫样品。
  
• Inert coating doesn't flake; more durable than Teflon?.内涂层稳定性和耐用性大大优于Teflon。
• TPED compliant cylinders now available for shipping into EU countries.
  
• All cylinders have 1/4" female NPT threads on both ends.所有的瓶子两端均为1/4英寸的阴螺纹。

Refinery and natural gas samples often contain trace amounts of sulfur-containing compounds which can interfere with reactions or poison catalysts in petrochemical processes. Because sulfur compounds quickly react with stainless steel surfaces, accurate determination of these compounds is impossible when samples are collected and stored in untreated sample cylinders. Restek's Sulfinert passivation technique bonds an inert silica layer into the surface of stainless steel, preventing active compounds from reacting with or adsorbing to the steel. These Swagelok high pressure sample cylinders are Sulfinert? treated for greater stability of sulfur compounds and mercury. DOT rating to 1,800 and 5,000psig allows sampling at gas wellheads as well as in the refinery. Use of high pressure sample cylinders is cited in ASTM D1265, Standard Practice for Sampling Liquefied Petroleum （LP） Gases, Manual Method.

炼油厂与天然气的取样样品里含有痕量的硫化物，它们会影响反应的正常进行或使催化剂中毒。因为含硫化物可以快速地与不锈钢表面起化学反应，所以用普通的采样罐采集样品是无法进行准确测定硫化物的含量的。RESTEK公司的硫钝化技术使耐硫腐蚀的惰性的物质附着在采样钢瓶的内表面，阻止了硫化物与不锈钢表面的反应。这些经过硫钝化的可耐高压的取样钢瓶是美国DOT钢瓶，可耐1800PSI和5000PSI的压力，这种高压采样钢瓶被引用入ASTM D1265标准，作为一般石油液化气抽样分析的方法。
