Industrial process piping networks are designed and constructed for long-term functionality. However, the system will eventually fail due to issues such as age, corrosion and even impact from external sources. If this is the case in your operation, you should consider replacing your piping network with stainless steel tubing. These are efficient for conveying diverse materials because the metal alloy is invulnerable to rusting. Moreover, the material is strong and can withstand mechanical stress and impact. On the other hand, selecting the right tubing for your application can be challenging since there are numerous stainless steel grades. Here is a description of the primary aspects that you should consider before purchasing the ideal tubing.

Pressure Rating

Stainless steel tubes are resilient, but the quality of their strength is not homogenous. Therefore, it is important to consider the pressure rating of the different products in the market before purchase. Basically, this property determines the amount of weight that the tube walls can support without distortion. You must consider the density of your industrial fluid and even the speed of the flow. For example, you will need a tube with higher pressure rating if you are handling chemical slurry as opposed to water. In addition, if the fluid is flowing fast, the walls have to be stronger because the motion will exert pressure on the walls.

Temperature Resistance

Temperature resistance is an important consideration if your new piping network is intended for handling hot or really cold fluids. In most cases, this is not a critical aspect because all forms of stainless steel are capable of withstanding exposure to diverse levels of heat. However, if heat is applied directly on the tubing or the fluid being conveyed is at any extreme temperature, the structural integrity of the pipe will be compromised gradually. For example, normal stainless steel that is alloyed using chromium will become brittle in low temperature and form scale when conveying hot fluids. However, a grade with nickel will maintain flexibility in cold, and if some manganese is also added, there will be minimal scaling.

Corrosion Factors

Finally, you should consider the possibility of corrosion and rusting of the stainless tubing after installation. Generally, standard stainless steel has chromium which prevents reaction with water and air and subsequent rusting. However, when the industrial fluid is saline or chemical, the material will still be subject to tarnish and wearing. You should choose tubing grades that match your applications. For example, purchase marine-grade 316 piping for handling saline fluids.
