What are the primary differences between welded and flanged joints?<\/strong><\/p>\n<p class=\"\" data-start=\"4667\" data-end=\"4832\"><span class=\"relative -mx-px my-[-0.2rem] rounded px-px py-[0.2rem] transition-colors duration-100 ease-in-out\">Welded joints involve the fusion of two pipe sections, creating a seamless and permanent connection.<\/span> <span class=\"relative -mx-px my-[-0.2rem] rounded px-px py-[0.2rem] transition-colors duration-100 ease-in-out\">Flanged joints consist of two flanges bolted together with a gasket in between, allowing for easy disassembly.<\/span> <span class=\"relative -mx-px my-[-0.2rem] rounded px-px py-[0.2rem] transition-colors duration-100 ease-in-out\">The primary differences lie in strength, maintenance requirements, and flexibility.<\/span>\u200b<\/p>\n<p class=\"\" data-start=\"4834\" data-end=\"4910\"><strong data-start=\"4834\" data-end=\"4910\">2. In what applications are welded joints preferred over flanged joints?<\/strong><\/p>\n<p class=\"\" data-start=\"4912\" data-end=\"5037\"><span class=\"relative -mx-px my-[-0.2rem] rounded px-px py-[0.2rem] transition-colors duration-100 ease-in-out\">Welded joints are preferred in high-pressure systems, such as oil and gas pipelines, where strength and leak resistance are critical.<\/span> <span class=\"relative -mx-px my-[-0.2rem] rounded px-px py-[0.2rem] transition-colors duration-100 ease-in-out\">They are also suitable for applications where space constraints make flanged joints impractical.<\/span>\u200b<\/p>\n<p class=\"\" data-start=\"5039\" data-end=\"5098\"><strong data-start=\"5039\" data-end=\"5098\">3.
