Stainless Steel Instrument Tubing Description

Our company has a large number of seamless stainless steel instrument tubing. Product quality is stable, internal and external polishing, our company has a large stock, and a variety of sizes, different wall thickness for customers to choose.Huashang stainless steel instrument tubing is in a comprehensive range of corrosion-resistant stainless steels and nickel alloys protecting outdoor diameters from (OD) 2.0 to 38 mm. All sizes are provided with clean surfaces and shut dimensional tolerances reducing the risk of leakages when connecting tubes with couplings.HUASHANG steel instrumentation tubing length is straight, but our tubes can additionally be delivered as coiled tubing, contributing to reduced installation costs. HUASHANG instrumentation tubes are characterized by using high cleanliness, and tubes with OD large than 5 mm are delivered with plugged ends for transport protection towards inside contamination. Instrumentation tubes are applied to many industries, such as Instruments and meters, Petroleum, Medicine, Chemical Industry, Water Purification, Gas and Pressure Vessel. In order to ensure the quality of the instrumentation tube, we will be according to the standard to do an inspection, such as chemical analysis, tensile, hardness, flattening, flaring, corrosion, and hydrostatic.
