• materialRed pine wood (with a thermal conductivity of 0.1~0.2 W/m · K), hardwood;Must undergo anti-corrosion treatment(Asphalt vacuum soaking/ACQ), insect and moisture resistant.

• structureSaddle arc, split type (wooden Haval); Thickness 30/40/50/80mm (≥ insulation thickness).

• Inner diameter formula：Inner diameter=Outer diameter of pipeline+2 x Thickness of insulation layer(Insulation commonly uses 30/40/50mm).

• Pipe diameter range：DN20~DN1000（Φ27~Φ1020mm）， Customizable.

• Supporting pipe cardHot dip galvanized U-shaped card (Q235), equipped with M8/M10/M12 bolts, rust proof for ≥ 5 years.

3、 Installation points (steps+spacing)

1. Bracket positioningHorizontal pipe spacing of 1.5-3m per piece; Install guide brackets on the 2nd to 3rd floors of the riser.

2. Selection of wooden palletsSelect the corresponding inner diameter and thickness based on the pipe diameter and insulation thickness,Thickness ≥ insulation layer thickness.

3. installation sequence：

• Fix the metal bracket (angle steel/channel steel), place half of the wooden support on the pipeline (insulated), fasten the other half of the wooden support (split Haf), and tighten it with U-shaped clamp bolts.

4. key details：

• Wooden supports, pipelines, and bracketsDense and void freePrevent water leakage from the cold bridge.

• Leave a gap of 3-5mm between the sliding bracket to adapt to thermal expansion and contraction.

• The tightness of the pipe clamp is moderate, without squeezing the insulation layer.

4、 Standard Basis (GB 50738-2011/GB 50243)

• Between hot and cold water pipes and bracketsInsulation pads must be installed(Anti corrosion wooden mat/flame-retardant hard insulation material).

• linerThickness ≥ insulation layer thicknessThe width is equal to or greater than the width of the support surface of the bracket, and it is complete and compact.

Dew condensation and dripping waterThe inner diameter of the wooden support is too small, the thickness is insufficient, or it is not corrosion-resistant, and the cold bridge is not blocked.

Insulation damageThe pipe clamp is too tight or the curved surface of the wooden support does not fit properly, squeezing the insulation layer.

vibration noiseThe wooden support is not firmly padded or the spacing between the brackets is too large, resulting in ineffective shock absorption.
