Sulfinert Treated Swagelok Sample Cylinders硫鈍化的取樣鋼瓶

• Sulfinert coating provides stable storage of sulfur and mercury at ppb levels in petroleum samples.硫鈍化的涂層為采樣罐提供了穩(wěn)定的性能，可以儲存PPB級的含硫樣品。
   
• Inert coating doesn't flake; more durable than Teflon?.內(nèi)涂層穩(wěn)定性和耐用性大大優(yōu)于Teflon。 
• TPED compliant cylinders now available for shipping into EU countries.
   
• All cylinders have 1/4" female NPT threads on both ends.所有的瓶子兩端均為1/4英寸的陰螺紋。

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.

硫鈍化的取樣鋼瓶，煉油廠與天然氣的取樣樣品里含有痕量的硫化物，它們會影響反應(yīng)的正常進行或使催化劑中毒。因為含硫化物可以快速地與不銹鋼表面起化學(xué)反應(yīng)，所以用普通的采樣罐采集樣品是無法進行準(zhǔn)確測定硫化物的含量的。RESTEK公司的硫鈍化技術(shù)使耐硫腐蝕的惰性的物質(zhì)附著在采樣鋼瓶的內(nèi)表面，阻止了硫化物與不銹鋼表面的反應(yīng)。這些經(jīng)過硫鈍化的可耐高壓的取樣鋼瓶是美國DOT鋼瓶，可耐1800PSI和5000PSI的壓力，這種高壓采樣鋼瓶被引用入ASTM D1265標(biāo)準(zhǔn)，作為一般石油液化氣抽樣分析的方法。
