Square ductwork is often considered in areas with limited ceiling height or where the route needs to closely follow a beam, but the dimensions must be calculated according to the HVAC specifications.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/onggiosaoviet.vn\/wp-content\/uploads\/2026\/04\/Anh-1-Bai-8-T4-600x450.png\" alt=\"\u1ed0ng gi\u00f3 vu\u00f4ng v\u00e0 ph\u1ee5 ki\u1ec7n h\u1ec7 th\u1ed1ng th\u00f4ng gi\u00f3 t\u1ea1i H\u1ea3i Ph\u00f2ng\"\/><figcaption class=\"wp-element-caption\">Illustrative image from the Sao Viet Wind Pipe image library.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Advantages of square ducting in HVAC systems<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Rectangular cross-sections facilitate easy ductwork layout in various technical layouts. Straight sections, elbows, tees, transition sections, and vents can be shown synchronously on the drawings to allow the construction team to check the support positions, maintenance clearances, and connection points. For renovation projects in Hai Phong, re-measuring ceiling heights and obstacles before finalizing dimensions helps minimize on-site modifications.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Specifications must be agreed upon before placing a manufacturing order.<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The cross-sectional dimensions and lengths of each section are as shown in the drawing.<\/li>\n\n\n\n<li>Material, thickness, and type of connection as per design, working pressure.<\/li>\n\n\n\n<li>Location of fittings such as elbows, tees, dampers, inspection hatches, and air vents.<\/li>\n\n\n\n<li>Require thermal insulation, fire protection, or soundproofing if specified in the project documents.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Thickness should not be chosen or cross-sectional area changed solely for manufacturing convenience. Any adjustments must be approved by the design engineer or project authority to avoid altering the expected flow rate and pressure loss.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Square duct installation in Hai Phong<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Contractors can submit drawings, bill of quantities, material specifications, and delivery schedules to Sao Viet Air Ducting for discussion and supply planning.
