ISO Ceramic Sleeve Lined Pipe Tee Corundum Ceramic Used In Metallurgy Ceramic Lined Tee Pipe

​Product Description

ELACERA ceramic sleeve-lined pipe tees provide wear protection at branch connections in metallurgical dust and powder conveying systems. The alumina ceramic lining protects the internal contact surface from abrasion, while the carbon steel body supports the fitting and its pipeline connections. Main-pipe diameter, branch dimensions, and connection details can be customized for the installation.

These fittings are useful where repeated wear at a collecting branch leads to patch repairs or premature replacement. Protecting the tee can help bring maintenance of this vulnerable connection closer to the planned shutdown schedule.

Wear Protection for Metallurgical Dust Lines

Dust collected around sintering, raw-material handling and mineral processing can contain hard, abrasive particles. As the dust travels through extraction pipework, these particles gradually remove material from unprotected steel surfaces.

A ceramic-lined tee can be considered for branch connections carrying iron-bearing dust, mineral fines and other abrasive powders into a collecting main. The lining provides a hard wear surface within the fitting, helping protect the steel body at a location that may otherwise require frequent attention.

The dust composition matters. Fine, dry powder and coarse particles carried over from a process do not place the same demands on the lining.

The Active Branches Matter

A collecting tee does not always operate under one steady flow condition. Several extraction points may run together during production, while only one branch remains active at other times.

When a dust-laden branch enters the main pipe, particle movement depends on the direction and relative strength of the two streams. Changes in branch operation can therefore change where particles strike the lining. A wear mark recorded during one production arrangement may not represent every operating condition.

For lining selection, it helps to identify which connections are inlets, which is the outlet, and which branches operate together. Normal airflow, maximum airflow, and changes in dust loading are more useful than a single average operating figure.

Why a Worn Tee Matters in a Suction Line

In pipework operating below atmospheric pressure, a worn opening can draw outside air into the extraction system. The fitting may therefore need attention even when little dust is visibly escaping.

This unwanted air contributes to the volume handled by the extraction system without collecting dust at the intended pickup point. Protecting the tee against abrasion helps preserve the condition of the ductwork and reduce recurring repairs.

The ceramic lining does not balance the extraction network or correct inadequate fan capacity. Its role is to protect the fitting while the ventilation system performs its designed duty.

Keep the Finished Bore in the Specification

For a lined tee, the steel pipe diameter alone does not describe the passage available to the material. Ceramic thickness and the supporting layer also occupy space inside the fitting.

The drawing should identify the finished internal diameter of both the main passage and the branch. This is particularly important when replacing an unlined tee within existing extraction pipework: fitting a liner inside the same steel shell reduces the available flow area.

The required bore should therefore be agreed before the steel body and lining dimensions are finalized. This allows wear protection and the required flow passage to be considered together.

Ceramic Material Reference

These are reference ceramic properties. The selected grade and acceptance requirements are confirmed with the order.

Higher hardness is only one part of the selection. Particle impact, temperature changes, and the way the ceramic is supported also affect the suitability of the finished tee. The lining construction should be specified for the actual duty.

FAQ

Can this tee improve dust collection at the extraction hood?

Its main function is wear protection. Keeping the pipework in good condition supports the extraction system, but suction at the hood also depends on airflow balance, duct resistance, fan performance and hood design.

Can a metallurgical tee be specified from the furnace temperature?

No. The relevant conditions are those at the fitting itself, including normal gas temperature, short temperature peaks, and any external heat exposure. The temperature capability of alumina alone does not establish the operating limit of the complete lined assembly.

Should the lining be changed if a branch starts carrying a different powder?

The duty should be reviewed. A change in particle size, hardness, moisture, or loading can alter the wear pattern, even when the pipe dimensions and airflow remain unchanged.

ELACERA supplies ceramic-lined tee fittings to confirmed drawings. For a metallurgical dust line, include the flow arrows, active branch combinations, and photographs of the existing wear area so the proposed lining can address the actual operating conditions.
