Metal hoses are particularly flexible between joints, making them more convenient to use. Many consumers choose this type of metal hose when they need one, so they want to know more about the types of metal hoses and purchasing tips, which will help them buy a product that meets their satisfaction. However, our understanding of metal hoses in daily life is very limited. Next, I will share some basic knowledge about metal hoses, hoping it will be helpful to everyone.
Metal Hose Models
Metal hoses are suitable for transporting liquids and all high-temperature media, with specifications ranging from DN20 to DN800mm, depending on the equipment and pipe diameter. The soft hoses are mainly made of stainless steel and come in specifications such as single buckle type P3 and double buckle type P4. The diameters of metal hoses generally range from 5mm to 100mm. The models are formulated according to the requirements of different manufacturers. The general coding rule for metal hoses is: company name code + hose inner diameter + hose outer diameter + single buckle or double buckle code. For example, TF0406D represents a single buckle metal hose produced by Tongfeng, with an inner diameter of 4mm and an outer diameter of 6mm.
