Detailed Introduction

The insulated wear-resistant composite tee is designed to address the problems that ordinary wear-resistant tees are not insulated and ordinary insulated tees are not resistant to scouring. The inner wear-resistant layer can be selected from ceramic lining, bimetal surfacing welding, rare earth alloy or rubber lining; the middle layer is a Q235B or 20# carbon steel pressure-bearing substrate; the outer layer is a high-density polyurethane or rock wool insulation layer; and the outermost layer can be optionally a PE, fiberglass-reinforced plastic or galvanized iron sheet protective shell. The product covers DN50–DN1200, with pressure ratings PN10–PN40, supports butt welding and flange connections, and includes equal-diameter, reducing and 45° inclined tee structures. It is suitable for branch diverting transportation of high-temperature dry powder, hot pulverized coal, high-temperature ore slurry, hot slag, desulfurization slurry and thermal circulation media. For specific configurations and prices, please contact us for confirmation.

Four-layer composite structure: the wear-resistant layer, carbon steel pressure-bearing layer, insulation layer and outer protective layer are integrally formed, reducing on-site secondary insulation construction.
The wear-resistant layer can be selected from ceramic lining, bimetal surfacing welding, rare earth alloy or rubber lining, adapting to different wear conditions such as high-temperature dry grinding, wet grinding and heavy-load impact.
The insulation layer uses polyurethane or high-temperature rock wool, with a density of ≥60kg/m³ and a thermal conductivity of ≤0.028W/(m·k), helping to reduce heat loss in the pipeline network.
It covers the full range of DN50–DN1200 and supports equal-diameter, reducing and 45° inclined tees, with connection methods available as butt welding or flange.
The outer protective layer can be optionally PE, fiberglass-reinforced plastic or galvanized iron sheet, adapting to direct-buried, overhead and high-cold outdoor laying environments.
At the factory, documents such as wear-resistant hardness testing, insulation thermal conductivity testing, hydrostatic pressure testing and material verification can be provided, facilitating engineering submission for approval and foreign trade customs clearance.

Overview

The thermal insulation and wear-resistant composite tee is a diverging and converging pipe fitting used for high-temperature powder, hot slag, high-temperature slurry and thermally worn pipeline networks. It integrates the wear-resistant layer, carbon steel pressure-bearing layer, thermal insulation layer and outer protective layer into an integrated composite structure, solving the problems that ordinary wear-resistant tees are not insulated and have large heat loss, and that ordinary insulated tees are not resistant to erosion and are easily worn through. Products cover DN50–DN1200, pressure rating PN10–PN40, support butt welding and flange connection, and include equal-diameter, reducing and 45° oblique tees. Suitable for pipeline network operation and maintenance, technical transformation and new construction projects in electric power, metallurgy, building materials, chemical and thermal industries.

Key Features

First, the four-layer composite structure combines wear resistance and thermal insulation together, reducing on-site secondary insulation construction. Second, the wear-resistant layer has four options: ceramic lining, bimetal overlay welding, rare earth alloy and rubber lining, which can be matched according to different working conditions such as high-temperature dry abrasion, wet abrasion and heavy-load impact. Third, the thermal insulation layer uses polyurethane or high-temperature rock wool, density ≥60kg/m³, thermal conductivity ≤0.028W/(m·k), helping to reduce pipeline network heat loss. Fourth, the outer protective layer can be PE, FRP or galvanized iron sheet, adapting to direct burial, overhead and severe cold outdoor environments. Fifth, before delivery, documents such as wear-resistant hardness testing, thermal insulation thermal conductivity testing, hydrostatic pressure testing and material verification can be provided, facilitating engineering approval and foreign trade customs clearance.

FAQ

How to choose a thermal-insulated wear-resistant composite tee for different working conditions?

For high-temperature dry ash and ash-conveying powder conditions, the ceramic-lined thermal-insulated type can be selected; for high-temperature coarse-particle impact conditions, the bimetal overlay welding thermal-insulated type can be selected; for high-temperature hot slag conditions within 350°C, the rare earth alloy thermal-insulated type can be selected; for hot and humid desulfurization slurry conditions, the rubber-lined thermal-insulated type can be selected. For specific selection, please contact us and provide the medium temperature, particle hardness and installation environment, and we will assist in confirming the configuration.

What is the difference between a thermal-insulated wear-resistant composite tee and an ordinary wear-resistant tee and an ordinary thermal-insulated tee?

Ordinary wear-resistant tees usually do not have a thermal insulation layer, resulting in large heat loss, and pipes may freeze in winter; ordinary thermal-insulated tees have insufficient wear resistance and are easily worn through by high-temperature particles or slag slurry. The thermal-insulated wear-resistant composite tee integrates the wear-resistant layer and the thermal insulation layer into one, which can both resist erosion and retain heat, prevent the medium from cooling and crystallizing, and reduce pipeline network energy consumption and operation and maintenance costs.

Will the composite layer delaminate and fall off?

The product adopts an integrated composite curing process, and the wear-resistant layer is tightly bonded to the substrate and the thermal insulation layer. Before leaving the factory, an adhesion test of the composite layer is performed. During the warranty period, for delamination and falling off caused by manufacturing defects, we provide free return and exchange and free replacement.

Does the thermal-insulated wear-resistant composite tee support customization?

Yes. In terms of dimensions, non-standard pipe diameters within the range of DN50–DN1200, thickened wall thickness, non-standard branch angles and eccentric flow-dividing structures can be customized; for the wear-resistant process, ceramic tiles, bimetal overlay welding, rare earth alloy casting or rubber lining can be selected; for the thermal insulation scheme, ordinary polyurethane, high-temperature rock wool or aerogel can be selected; the outer protective layer, substrate material, pressure rating and thermal insulation thickness can also be confirmed according to project requirements. Production can be carried out according to drawings, samples or technical agreements, and English shipping marks and LOGO customization are supported.

What are the delivery time and warranty period?

DN50–DN300 conventional ceramic or rubber-lined direct-buried and above-ground standard models are in stock, and shipment can be arranged within 24–48 hours after order confirmation. For non-standard customizations and bulk engineering orders, please contact us to confirm the delivery lead time. The product warranty period is 18 months. During the warranty period, for problems caused by manufacturing defects, we provide free returns and exchanges and free replacements.
