Three-Layer PE Insulation Structure

XLBAODI mini split line sets use a three-layer LDPE + IXPE + PE insulation structure designed to protect the copper refrigerant pipe and reduce thermal loss.

Inner LDPE Layer

The inner layer provides a smooth protective surface around the copper tube and helps improve moisture and friction resistance.

Middle IXPE Layer

The cross-linked polyethylene foam layer provides thermal resistance and helps reduce heat transfer between the refrigerant pipe and the surrounding environment.

Outer PE Layer

The outer protective layer improves resistance to UV exposure, abrasion, moisture, and mechanical wear during installation and long-term use.

This multi-layer construction makes PE insulated copper pipe suitable for indoor and outdoor HVAC installations where thermal performance and durability are important.

Copper Tube Material and HVAC Standards

The performance of a mini split line set depends heavily on the quality and dimensional consistency of the copper tubing.

XLBAODI uses 99.9% high-purity C1220T copper tubing manufactured according to internationally recognized HVAC copper tube standards, including:

• ASTM B280

• EN12735

• AS1571

• JIS H3300 C1220T

Consistent copper tube diameter and wall thickness help provide reliable refrigerant flow, installation flexibility, and pressure performance for HVAC and refrigeration applications.

Designed for Mini Split and HVAC Refrigerant Systems

PE insulated copper line sets provide the connection between indoor and outdoor HVAC equipment, carrying refrigerant through the cooling and heating cycle.

Typical applications include:

• Ductless mini split air conditioners

• Split air conditioning systems

• Heat pump systems

• HVAC refrigerant piping

• Residential air conditioning systems

• Light commercial HVAC systems

• Pre-insulated copper tubing assemblies

Different refrigerants and HVAC equipment may require different copper tube dimensions, wall thicknesses, and system pressure ratings. The appropriate line set should therefore be selected according to the HVAC equipment manufacturer's specifications.

How to Choose the Right Mini Split Line Set

Choosing the correct insulated copper line set is important for HVAC efficiency, installation reliability, and long-term system performance.

1. Check the Copper Tube Size

The liquid and suction line sizes should match the requirements of the air conditioner or heat pump.

Common copper tube diameters include 1/4", 3/8", 1/2", 5/8", 3/4", and 7/8".

Always refer to the HVAC equipment manufacturer's specifications when selecting the correct combination.

2. Select the Appropriate Insulation Thickness

Insulation thickness affects heat transfer and condensation control.

XLBAODI offers:

• 8mm

• 9mm

• 10mm

• 12mm

• 19mm

• Customized thicknesses

The appropriate thickness depends on the installation environment, climate conditions, piping location, and applicable project requirements.

3. Confirm Copper Tube Standards

Copper refrigerant tubing should meet the standards required for the target HVAC market or project.

XLBAODI can provide copper tubing manufactured according to ASTM B280, EN12735, AS1571, and JIS H3300 specifications.

4. Determine the Required Line Set Length

Available lengths can be customized according to installation and distribution requirements.

XLBAODI supports lengths from 3m to 30m, as well as customized specifications for OEM orders.

5. Confirm Refrigerant and Equipment Requirements

Before ordering, confirm the required pipe size, wall thickness, operating pressure, refrigerant type, and equipment specifications.

This helps ensure that the selected copper line set is suitable for the intended HVAC system.
