产品介绍：
Product Introduction: This product is composed of nickel-chromium alloy steel and a high-molecular high-temperature resistant
precision woven protective layer. The spiral wire-wrapped permeable pipe has high strength in terms of pressure resistance and rust
prevention, and is a new type of drainage pipe material worth promoting.
Product specifications: The straight outer diameter of the spiral wire-wrapped permeable pipe is 32mm, and the inner diameter size
is 25mm. The weight per meter is 800 grams, the thickness of the metal square steel is 2mm, and the diameter of the nano-protective
layer wire is 1.5mm.
Product features The metal support body of the spiral wire-wrapped permeable pipe is made of (nickel-chromium alloy steel), which
has a high load-bearing capacity and can withstand a linear pressure of 300kn per meter. The nano-temperature-resistant composite
material can remain unmelted at 200℃ for 30 minutes. Under high-temperature construction conditions when covered with asphalt
concrete, it can maintain its non-brittleness, non-wrinkling and non-deformation. It also has a certain resistance to acid and alkali
corrosion. Meanwhile, the spiral wire-wrapped permeable pipe has certain tensile properties and anti-freezing effects, does not
blend with oil stains or adhere to dust, ensuring smooth drainage.
Application scope: Currently, it is mainly used for drainage on elevated Bridges. The laying position is arranged longitudinally along
the root of the bridge's edge impact wall and in cast iron drainage channels.
