Schedule 10 Stainless Steel Pipe Pressure Rating Chart
Stainless steel pipes are widely used in industries that require high corrosion resistance and strength. These pipes come in different schedules, which are determined by the wall thickness and diameter of the pipe. Schedule 10 stainless steel pipe is one of the most commonly used schedules due to its moderate pressure rating and ease of installation. This article will discuss the pressure rating chart for schedule 10 stainless steel pipes.
What is Schedule 10 Stainless Steel Pipe?
Schedule 10 stainless steel pipe has a wall thickness of 0.109 inches and an outer diameter of 1.315 inches. This schedule is commonly used in low-pressure applications such as water supply, drainage, and heating systems. Schedule 10 stainless steel pipes are also used in food and beverage industries due to their high corrosion resistance.
Pressure Rating Chart for Schedule 10 Stainless Steel Pipe
The pressure rating chart for schedule 10 stainless steel pipe is based on the American National Standards Institute (ANSI) B36.19M standard. This chart provides the maximum allowable working pressure (MAWP) at different temperatures for various sizes of schedule 10 stainless steel pipes.
For example, a 1-inch schedule 10 stainless steel pipe has a MAWP of 1,029 psi at 100°F, 952 psi at 200°F, and 700 psi at 500°F. The MAWP decreases as the temperature increases due to the reduced strength of the material at higher temperatures.
Factors Affecting the Pressure Rating of Schedule 10 Stainless Steel Pipe
The pressure rating of schedule 10 stainless steel pipe is affected by several factors such as the temperature, fluid type, and pipe length. Higher temperatures reduce the MAWP, while certain fluids such as corrosive chemicals can also reduce the pressure rating. The length of the pipe also affects the pressure rating as longer pipes have higher friction losses, which can reduce the flow rate and increase the pressure drop.
Installation of Schedule 10 Stainless Steel Pipe
Installation of schedule 10 stainless steel pipe is relatively easy due to its lightweight and thin wall thickness. However, it is important to use the correct fittings and tools to avoid damaging the pipe. Stainless steel pipes should also be properly supported to prevent sagging and excessive stress on the joints.
Advantages of Schedule 10 Stainless Steel Pipe
Schedule 10 stainless steel pipe offers several advantages over other materials such as copper and PVC. Stainless steel pipes are highly corrosion-resistant, which makes them ideal for use in harsh environments. They also have a long lifespan and require minimal maintenance, which reduces the overall cost of ownership.
Conclusion
Schedule 10 stainless steel pipe is a widely used schedule due to its moderate pressure rating and ease of installation. The pressure rating chart for schedule 10 stainless steel pipe provides the MAWP at different temperatures for various sizes of pipes. The pressure rating is affected by several factors such as the temperature, fluid type, and pipe length. Installation of schedule 10 stainless steel pipe is relatively easy, and the material offers several advantages over other materials such as copper and PVC.
