4. Stainless steel conservation

Stainless steel is a popular metal for appliances these days. Many kitchen appliances, both large and small, are made with stainless steel. Pots and pans and eating utensils are also made with stainless steel. One advantage of stainless steel is that is very resistant to rusting. But it can get rust stains from transference of rusty objects. You can keep stainless steel rust-free by following a few simple steps.

Clean frequently with a cleaner and water. Any cleaner that is safe for glass is usually safe for stainless steel.
Scrub off all rust from these objects with a scrubbing pad or steel wood pad. This means getting rid of rust from pots and pans before putting them into a stainless steel sink or on top of a stainless steel stove.
Put a rubber mat at the bottom of the stainless steel sink before placing rusted pots and pans (such as cast iron cookware) in the sink.
Apply a thin layer of lubricant (such as mineral oil) to the surface of the stainless steel. This prevents rust from forming.
Inspect equipment frequently, if you notice discoloration, tarnish or water stains, increase the frequency of your fresh water rinses to reduce accumulated chemicals

Q:How do you calculate the wall thickness for stainless steel pipes under external pressure?: To calculate the wall thickness for stainless steel pipes under external pressure, you need to consider various factors such as the material properties, design codes, and the applied external pressure. Here is a general approach to calculating the wall thickness: 1. Determine the design pressure: The first step is to identify the external pressure that the stainless steel pipe will be subjected to. This pressure can be due to factors like fluid flow, environmental conditions, or operational requirements. 2. Determine the material properties: Stainless steel pipes have different grades, each with its own mechanical properties. Consult the material specifications to obtain the values for the yield strength (Sy) and ultimate tensile strength (Su) of the specific stainless steel grade you are working with. 3. Determine the allowable stress: The allowable stress (Sa) is the maximum stress that the material can sustain under the given conditions. It is usually provided by design codes or standards such as ASME B31.3 for process piping or ASME Section VIII for pressure vessels. 4. Calculate the design pressure thickness: Use the following formula to calculate the design pressure thickness (t): t = (P * D) / (2 * Sa) where P is the design pressure and D is the outside diameter of the stainless steel pipe. 5. Determine the corrosion allowance: Since stainless steel is prone to corrosion, it is important to consider a corrosion allowance to ensure the longevity of the pipe. The corrosion allowance is typically specified by the design codes or industry standards. 6. Calculate the final wall thickness: Add the corrosion allowance to the design pressure thickness calculated in step 4 to obtain the final wall thickness. It is important to note that this is a general approach, and specific design codes or standards may have additional requirements or factors to consider. Therefore, it is recommended to consult the relevant design codes, standards, or a qualified engineer to ensure accurate and safe calculations for your specific application.
