Aluminum Silicate Insulation Tube

Aluminum Silicate Insulation Tube is a preformed fiber section for boiler pipework, process-heating lines, and high-temperature service branches.
Selection starts with the pipe outside diameter. The required inside diameter, wall thickness, length, temperature grade, facing, and joint method are then confirmed from the line data.

Description

 

Aluminum Silicate Insulation Tube closes around a hot pipe as a shaped layer, reducing the amount of on-site forming needed. A correct bore keeps both halves or the split section in contact with the pipe, while the wall thickness provides the planned insulation depth. Supports, valves, bends, and removable items still require separate cuts, so those points are included in the order schedule.

Quality Check

 
 
01
 

Before loading, the warehouse checks the Aluminum Silicate Insulation Tube diameter mark, wall thickness, quantity, visible surface, and package identification.

 
02
 

Different bore sizes are packed separately where practical, allowing installers to match each bundle to the pipe schedule without sorting mixed sections.

Certifications & Qualifications

 

product-1190-1682

Finished-tube dimensions are controlled by the order and TDS. A conformity document for blanket material must not be renamed as a tube certificate.

The available related UDEM record covers Aluminum Silicate Needled Blanket under EN 13162:2012+A1:2015, certificate M.2025.206.C125156, model Xinyafeng/96kg-3600*610*50mm.

This file may support the fiber material used in the tube, but the tube bore, wall thickness, and length remain order-specific and should appear in the packing list or technical data.

Company approvals include FAP25259601QRO for quality management, FAP25259601ERO for environmental management, and FAP25259601SRO for occupational health and safety, following the applicable ISO standards.

TDS, MSDS, labels, photographs, customs papers, and the size-based packing list can be provided with the shipment.

 

FAQ

 

Q: Why must the pipe outside diameter be accurate?

A: The bore has to close around the pipe. An incorrect diameter can create a gap or prevent the split seam from meeting.

Q: How should tube sections be stored?

A: Keep them dry, support them without crushing, and separate them from sharp tools or heavy bundles.

Q: What should remain accessible after insulation?

A: Unless the approved drawing says otherwise, valves, identification plates, removable covers, and service points should not be permanently enclosed.
