Duct specifications
Introducing "duct classification" and "the pitch of spiral duct seams"!
Here is an introduction to the specifications of ducts. The classification of ducts is as follows: "Low-pressure ducts" have a positive pressure of 500 or less and a negative pressure within -500. "High-pressure 1 ducts" exceed a positive pressure of 500 but are 1,000 or less, and have a negative pressure exceeding -500 but within -1,000. "High-pressure 2 ducts" exceed a positive pressure of 1,000 but are 2,500 or less, and have a negative pressure exceeding -1,000 but within -2,000. Additionally, we provide information on "the thickness of straight pipes for spiral ducts," "the thickness of joints for spiral ducts," and "joining materials" in a PDF document, so please refer to it for more details. 【Duct Classification】 ■ Low-pressure duct ・Positive pressure: 500 or less / Negative pressure: within -500 ■ High-pressure 1 duct ・Positive pressure: exceeding 500 but 1,000 or less / Negative pressure: exceeding -500 but within -1,000 ■ High-pressure 2 duct ・Positive pressure: exceeding 1,000 but 2,500 or less / Negative pressure: exceeding -1,000 but within -2,000 *For more details, please refer to the PDF document or feel free to contact us.
