rinsing\u2014require flat spray nozzles that generate a fan-shaped spray pattern, covering a wide area of a moving workpiece and making them indispensable in these operations.<\/p>\n<p><img

\/><br \/>\nStainless steel flat spray nozzle<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">\nBecause sheet widths can reach about two meters, multiple nozzles are mounted on a header with a twist angle (offset angle*) rather than aligned horizontally across the width, where overlapping the edges of adjacent spray patterns produces a uniform distribution across the entire surface.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 0.9rem;line-height:1.5rem\">\n*For more details on offset angle adjustment, please refer to

number of the flat spray nozzles, whose performance directly dictates the quality of steel sheets. Yet the recirculated water used for rinsing carries impurities and foreign matter into the nozzles, causing frequent clogging and degrading their performance. <\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">This necessitates scheduled maintenance that involves removing entire headers, detaching nozzles for cleaning or replacement, and readjusting offset angles upon reinstallation\u2014a time-consuming and labor-intensive process for on-site operators.<\/p>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<\/div>\n<p><!-- Solutions Proposed by IKEUCHI\u3000\u2605p\uff5e\/p\u3067\u6bb5\u843d\u533a\u5207\u308a \u2605\u753b\u50cfURL\u3092\u201d\u3053\u3053\u306bURL\"\u306e\u4f4d\u7f6e\u306b\u5165\u308c\u308b\u3002\u753b\u50cf\u30b5\u30a4\u30ba\u306f\u5143\u548c\u6587HTML\u53c2\u8003\u3000--><\/p>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-bottom:0.8rem;background:url(https:\/\/www.dry-fog.com\/jp\/wp-content\/uploads\/sites\/2\/2024\/10\/10px-45px.svg) no-repeat 0 0;background-size:auto 30px;padding-left: 20px\">\n<h3 style=\"font-size: 1.5rem\">Solutions Proposed by IKEUCHI<\/h3>\n<\/div>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">To address this challenge, IKEUCHI introduces the stainless-steel flat spray nozzle <a href=\"https:\/\/www.dry-fog.com\/en\/products\/noz-hyd-invv-ss\/\" style=\"color: #00a273\" target=\"_blank\" rel=\"noopener\">INVV-SS<\/a> Series, a newly launched product.<br \/>\nThe INVV-SS features a detachable <span style=\"font-weight:bold;font-size: 1rem\">nozzle-tip section<\/span> consisting of a nozzle tip, cap, and packing. This section <span style=\"font-weight:bold;font-size: 1rem\">can be removed and replaced independently<\/span>, while the nozzle adaptor remains fixed to the header.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">This design <span style=\"font-weight:bold;font-size: 1rem\">eliminates the need to remove entire nozzles from the header during maintenance<\/span>. Operators can replace only the nozzle tip at clogged locations, or exchange all tips at once and clean them later in a safe area for reuse as spares.<br \/>\nIn either case, <span style=\"font-weight:bold;font-size: 1rem\">no readjustment of offset angles on the adaptors is required<\/span>, significantly reducing on-site maintenance workload.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2025\/10\/nozzle-steel-007-image_04.png\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/><br \/>\nLeft: Adaptor + Nozzle Tip Assembly | Right: Nozzle tip detachable while Adaptor remains fixed to the header<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">The customer immediately grasped the advantage, remarking that the design would <span style=\"font-weight:bold;font-size: 1rem\">greatly reduce maintenance effort<\/span>.
