Product Description

The threaded pipe tee is a high-strength forged fitting designed to connect three pipelines at a 90-degree angle, allowing for branch line creation in tight spaces where welding is impractical or prohibited. The threaded pipe tee is manufactured to ASME B16.11 standards, this fitting ensures precise thread alignment and pressure integrity.

Product Advantages

No Welding Required

The threaded pipe tee eliminates the need for qualified welders and X-ray inspection on site. This drastically reduces installation labor costs and project timelines.

Maintenance Flexibility

Threaded connections allow for easy removal and replacement of downstream equipment (like valves or gauges) without cutting the pipe, saving significant downtime and material replacement costs.

Main Applications

Chemical Processing

Low-pressure chemical lines and sampling points.

Power Generation

Turbine lubrication lines, boiler drain lines, and instrument air.

Shipbuilding & Marine Engineering

Ballast systems, hydraulic lines, and firefighting systems onboard.

FAQ

Q1: What is the main advantage of using a threaded tee instead of a welded tee?

A1: The primary advantage is safety and simplicity in installation. In hazardous environments (like chemical plants or refineries) where hot work (welding) permits are difficult to obtain, the threaded pipe tee allows for cold installation. Furthermore, it allows for future disassembly for maintenance, which is impossible with a welded fitting without cutting the pipe.

Q2: How do I choose between a 3000# and a 6000# threaded tee for my system?

A2: The choice depends on your system's pressure and wall thickness schedule. Generally, use 3000# fittings for pipes with Schedule 160 wall thickness, and 6000# fittings for double extra strong (XXS) pipe walls. If your pipeline pressure exceeds the rating of a 3000# fitting at your operating temperature, or if you are connecting to heavy-wall pipe, you must step up to the 6000# rating to ensure the fitting body does not fail before the pipe does. Always consult the ASME B31.3 pressure-temperature ratings for confirmation.
