A higher schedule number means a thicker wall.<\/p>\n<p>Thicker walls allow the pipe to handle higher internal pressure. The outside diameter (OD) stays the same for a given pipe size regardless of schedule.<\/p>\n<p>Only the inside diameter (ID) changes.<\/p>\n<p>The schedule system was developed to standardize pipe wall thicknesses across manufacturers.<\/p>\n<p>Today, common schedules include SCH 10, SCH 20, SCH 40, SCH 80, SCH 120, SCH 160, and XXS (Double Extra Strong).<\/p>\n<h2>Schedule 40 Pipe<\/h2>\n<p>Schedule 40 is the most commonly used pipe schedule in residential and commercial plumbing.<\/p>\n<p>It offers a good balance between wall thickness and cost. SCH 40 is suitable for low to moderate pressure applications.<\/p>\n<p>It is available in carbon steel, stainless steel, PVC, and other materials.<\/p>\n<p>For example, a 2-inch SCH 40 carbon steel pipe has an OD of 2.375 inches and a wall thickness of 0.154 inches.<\/p>\n<p>t handles pressures up to approximately 1,000 PSI, depending on material and temperature.<\/p>\n<h2>Schedule 80 Pipe<\/h2>\n<p>Schedule 80 has a thicker wall than Schedule 40. It handles higher pressure and offers greater mechanical strength.<\/p>\n<p>SCH 80 is common in industrial piping, chemical processing, and oil and gas applications.<\/p>\n<p>A 2-inch SCH 80 carbon steel pipe has the same OD of 2.375 inches. However, the wall thickness increases to 0.218 inches.<\/p>\n<p>This reduces the inside diameter and increases pressure capacity significantly.<\/p>\n<h2>Schedule 160 Pipe<\/h2>\n<p>Schedule 160 is a heavy-duty option designed for very high-pressure systems.<\/p>\n<p>It has a much thicker wall than SCH 40 or SCH 80. SCH 160 is used in refineries, high-pressure steam systems, and hydraulic systems.<\/p>\n<p>It is more expensive and heavier, but essential where safety is critical.<\/p>\n<h2>SCH 40 vs SCH 80 vs SCH 160: Comparison<\/h2>\n<ul>\n<li>Wall thickness: SCH 40 &lt; SCH 80 &lt; SCH 160. Each step up increases wall thickness significantly.<\/li>\n<li>Inside diameter: As the schedule number increases, the inside diameter decreases. This reduces flow volume.<\/li>\n<li>Pressure rating: Higher schedule pipes handle greater internal pressure. SCH 160 handles roughly twice the pressure of SCH 40.<\/li>\n<li>Weight: Higher schedule pipes are heavier. SCH 160 can weigh 2\u20133 times more than SCH 40 in equivalent sizes.<\/li>\n<li>Cost: SCH 40 is the most affordable. SCH 160 can cost 3\u20134 times more per foot due to additional material.<\/li>\n<li>Applications: SCH 40 suits water and gas distribution. SCH 80 is for industrial use. SCH 160 is for extreme-pressure systems.<\/li>\n<\/ul>\n<h2 class=\"\"><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone size-full wp-image-1304\" src=\"https:\/\/pipenipples.com\/wp-content\/uploads\/2026\/05\/schedule-40-vs-80-vs-160.jpg\" alt=\"schedule 40 vs 80 vs 160\" width=\"800\" height=\"450\" srcset=\"https:\/\/pipenipples.com\/wp-content\/uploads\/2026\/05\/schedule-40-vs-80-vs-160.jpg 800w, https:\/\/pipenipples.com\/wp-content\/uploads\/2026\/05\/schedule-40-vs-80-vs-160-600x338.jpg 600w, https:\/\/pipenipples.com\/wp-content\/uploads\/2026\/05\/schedule-40-vs-80-vs-160-150x84.jpg 150w, https:\/\/pipenipples.com\/wp-content\/uploads\/2026\/05\/schedule-40-vs-80-vs-160-768x432.jpg 768w, https:\/\/pipenipples.com\/wp-content\/uploads\/2026\/05\/schedule-40-vs-80-vs-160-24x14.jpg 24w, https:\/\/pipenipples.com\/wp-content\/uploads\/2026\/05\/schedule-40-vs-80-vs-160-36x20.jpg 36w, https:\/\/pipenipples.com\/wp-content\/uploads\/2026\/05\/schedule-40-vs-80-vs-160-48x27.jpg 48w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/h2>\n<h2>How to Choose the Right Schedule<\/h2>\n<p>Start with your system&#8217;s maximum operating pressure. Apply a safety factor of at least 1.5 to determine minimum required pressure rating.<\/p>\n<p>Then consider temperature, fluid type, and corrosion risk. Finally, check applicable standards such as <a href=\"https:\/\/engstandards.lanl.gov\/esm\/pressure_safety\/Section%20REF-3-R0.pdf\" target=\"_blank\" rel=\"nofollow noopener\">ASME B31.3<\/a> for process piping or <a href=\"https:\/\/www.nrc.gov\/docs\/ML0314\/ML031470592.pdf\" rel=\"nofollow noopener\" target=\"_blank\">ASME B31.1<\/a> for power piping.<\/p>\n<p>For most water and gas distribution systems, SCH 40 is sufficient. For industrial process lines, SCH 80 is typically recommended.<\/p>\n<p>For high-pressure steam or hydraulic systems, SCH 160 or XXS may be required.<\/p>\n<h2>Conclusion<\/h2>\n<p>Pipe schedule is a critical factor in safe and efficient piping design.<\/p>\n<p>SCH 40 vs SCH 80 vs SCH 160 represents a trade-off between wall thickness, pressure capacity, weight, and cost.<\/p>\n<p>SANVO manufactures steel pipes in all standard schedules to ASTM, ASME, and API standards.<\/p>\n<p><a href=\"\/es\/contact\/\" target=\"_blank\" rel=\"noopener\">Request a free sample or get a custom quote<\/a> from our factory today.<\/p>\n<div class=\"memorize_new_word_loading\" style=\"display: none;\"><\/div>\n<div class=\"bv-shadow-dom bv-shadow-dom-fade_out\"><\/div>","protected":false},"excerpt":{"rendered":"<p>What Is Pipe Schedule?
