View Price List & Sizes of 304/ 316 Stainless Steel Instrument Stilling Tubing

316 Stainless Steel Instrument Stilling Tubing is one of the types in the instrument tubing. The instrument tubes can range in dimensions such as diameters, wall thicknesses and lengths. There are various materials that are used to make these tubes. The most used are the 304, 304L, 316 and 316L grades. But there are other, high alloy and expensive materials. The Instrument Tubing Material needs to be able to handle machining and forming operations. The instruments used in power distribution, automotive, chemical, petrochemical, oil and gas, process instruments, sensing instruments and others need special metals or special materials. The Stainless Steel Instrumentation Tubing is used in hydraulic applications and in other high pressure applications.

There are chemical inhibition instruments, impulse lines and others as well. The Instrument Stilling Tube can come in different dimensions. There are custom cut to length sizes available as well. Depending on the requirements of the instruments, the materials need to have different heat resistant, corrosion resistant, abrasion resistant, elongation and other characteristics. The 304 SS Instrument Tube is used in high corrosive and steam application instruments because brass is resistant to acidic and steam corrosion. The instrument tubing is usually of smaller diameter size in the range of ¼ inches to 2 ½ inches.
