The nozzles, subjected to these elevated temperatures, conducted heat from the nozzle tips to the piping, causing damage. Although the nozzle tips were regularly replaceable, frequent piping replacement demanded considerable time and expense.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">Seeking a solution to mitigate piping damage and enhance maintenance efficiency, the customer turned to us for assistance.<\/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<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\">Proposals from IKEUCHI<\/h3>\n<\/div>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">Initially, we considered covering the nozzle section with a sleeve to reduce heat damage to the nozzle piping. However, this approach would have required managing the replacement schedule for both the nozzle and the sleeve, leading to complex maintenance procedures and a risk of oversight in the field.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">To address this, we proposed a unit design where <span style=\"font-weight:bold;font-size: 1.0rem\">the nozzle section and sleeve are welded together, allowing both to be replaced simultaneously<\/span>. This structure eliminates gaps between the nozzle and sleeve, further enhancing the protective performance of the nozzle piping.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2024\/12\/noz-pne-coo_001.jpg\" alt=\"\" width=\"1600\" height=\"600\" class=\"alignleft size-full wp-image-6252\" \/><br \/>\n<img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2024\/12\/noz-pne-coo_005.jpg\" alt=\"\" width=\"1600\" height=\"601\" class=\"alignleft size-full wp-image-6257\" \/><\/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<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\">Benefits Achieved<\/h3>\n<\/div>\n<ul style=\"list-style-type: disc;margin-left:2.8rem;font-size: 1rem;line-height:1.6rem\">\n<div style=\"margin-bottom:0.8rem\">\n<li>Eliminating the need to manage separate replacement schedules for the nozzle section and sleeve has significantly enhanced maintainability.
