F316 Y Type Strainer<\/strong> is a Class 1500 high-pressure stainless steel pipeline strainer manufactured with ASTM A182 F316 components and a removable filtration screen.<\/p>\n<h2>What is the size of this Y strainer?<\/h2>\n<p class=\"isSelectedEnd\">This model is <strong>12 pouces<\/strong>, equivalent to approximately <strong>DN300<\/strong> nominal pipe size.<\/p>\n<h2>What does 1500LB mean?<\/h2>\n<p class=\"isSelectedEnd\">1500LB refers to the <strong>ASME Class 1500 pressure class<\/strong>. The actual allowable pressure depends on the material, operating temperature, applicable pressure-temperature rating, design standard, and project requirements.<\/p>\n<h2>What does F316 mean?<\/h2>\n<p class=\"isSelectedEnd\">F316 refers to a molybdenum-bearing austenitic stainless steel grade. It provides good corrosion resistance and improved resistance to pitting compared with conventional 304 stainless steel in many environments.<\/p>\n<h2>What is an RTJ flange?<\/h2>\n<p class=\"isSelectedEnd\">RTJ means <strong>Ring Type Joint<\/strong>. It is a high-pressure flange sealing system that uses a metallic ring gasket installed into a precision-machined annular groove.<\/p>\n<h2>Why use an RTJ flange?<\/h2>\n<p class=\"isSelectedEnd\">RTJ connections are commonly selected for high-pressure and critical services because they provide a robust metallic sealing arrangement when correctly designed and installed.<\/p>\n<h2>Can this strainer be used for oil and gas?<\/h2>\n<p class=\"isSelectedEnd\">Yes. The <strong>Class 1500 F316 Y Strainer<\/strong> can be used in suitable oil &amp; gas and hydrocarbon applications, subject to fluid compatibility, temperature, pressure, and project specifications.<\/p>\n<h2>Can the screen be customized?<\/h2>\n<p class=\"isSelectedEnd\">Yes. STV Valves can provide different screen materials, perforations, mesh sizes, and filtration configurations according to the required flow and particle removal requirements.<\/p>\n<h2>Can F316 be used for seawater?<\/h2>\n<p class=\"isSelectedEnd\">F316 has good general corrosion resistance, but continuous seawater exposure can be highly aggressive. Duplex, Super Duplex, Titanium, or other specialized materials may be more appropriate depending on the application.<\/p>\n<h2>Can STV Valves provide RTJ strainers?<\/h2>\n<p class=\"isSelectedEnd\">Yes. STV Valves can manufacture high-pressure strainers with <strong>RTJ flanges<\/strong> and customized body, screen, gasket, inspection, and documentation requirements.<\/p>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h1>Technical Summary<\/h1>\n<p class=\"isSelectedEnd\">Le <strong>1500LB F316 Y Type Strainer, 12 Inch, RTJ Flange<\/strong> is a high-pressure stainless steel filtration solution designed for critical industrial piping systems.<\/p>\n<p class=\"isSelectedEnd\">With <strong>ASTM A182 F316 construction<\/strong>, a removable stainless steel screen, <strong>Class 1500 pressure rating<\/strong>, et <strong>RTJ flange connection<\/strong>, this <strong>12 Inch Y Type Strainer<\/strong> is suitable for demanding oil &amp; gas, refinery, petrochemical, chemical processing, offshore, and industrial applications.<\/p>\n<p class=\"isSelectedEnd\">The combination of F316 corrosion resistance, high-pressure construction, large-diameter flow capacity, and RTJ sealing makes this strainer a practical solution for protecting downstream equipment in demanding process systems.<\/p>\n<p><strong>Contact STV Valves for a GA drawing, technical datasheet, RTJ flange details, screen specification, pressure-temperature data, material certificate, inspection plan, or customized quotation.<\/strong><\/p>","protected":false},"excerpt":{"rendered":"<h1 class=\"mt-6 mb-2 font-semibold text-3xl\" data-streamdown=\"heading-1\"><strong>1500LB F316 Y Type Strainer, 12 Inch, RTJ Flange<\/strong><\/h1>\n<p>STV Valve Technology Group C o., Ltd is a professional leader China 1500LB F304 Y Type Strainer,6 Inch \u00a0F304 Y Type Strainer \u00a0Stainless Steel Pipeline Strainer,Industrial Y Strainer,High Pressure Strainer,Oil &amp; Gas Y Strainer,Petrochemical Y Strainer,China Y Strainer Manufacturer,China Y Strainer Supplier,Industrial Strainer Manufacturer,STV Valves with high quality and competitive price.<\/p>","protected":false},"featured_media":8991,"template":"","meta":[],"product_brand":[],"product_cat":[85,48],"product_tag":[4308,4317,4313,4309,4312,4185,1256,4314,4172,4310,4311,4319,4176,4184,4306,4307,4318,4315,4316,4204],"class_list":["post-8990","product","type-product","status-publish","has-post-thumbnail","product_cat-stainless-steel-y-type-strainer","product_cat-y-strainer","product_tag-12-inch-f316-y-strainer","product_tag-12-inch-y-type-strainer","product_tag-1500lb-rtj-y-strainer","product_tag-1500lb-y-type-strainer","product_tag-astm-a182-f316-y-strainer","product_tag-china-y-strainer-manufacturer","product_tag-china-y-strainer-supplier","product_tag-class-1500-rtj-strainer","product_tag-class-1500-y-strainer","product_tag-dn300-y-strainer","product_tag-f316-stainless-steel-y-strainer","product_tag-high-pressure-pipeline-strainer","product_tag-high-pressure-y-strainer","product_tag-industrial-y-type-strainer","product_tag-oil-gas-y-strainer","product_tag-petrochemical-y-strainer","product_tag-refinery-y-strainer","product_tag-rtj-flange-y-strainer","product_tag-stainless-steel-y-strainer","product_tag-stv-valves","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/product\/8990","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/media\/8991"}],"wp:attachment":[{"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/media?parent=8990"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/product_brand?post=8990"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/product_cat?post=8990"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.stvvalves.com\/fr\/wp-json\/wp\/v2\/product_tag?post=8990"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
