Compression Forged Tee

High-pressure hot and cold water system: Main pipes of commercial buildings, high-rise residential buildings, boiler rooms and other occasions that require higher pressure bearing capacity.
Compressed air system: Main gas lines of factories, branch points that need to withstand frequent pressure fluctuations or shocks.
Hydraulic system (medium and low pressure): Branch connections of oil circuits with high requirements for sealing and strength (oil compatibility needs to be confirmed).
Fuel system: Oil supply pipelines for fuel boilers and industrial burners.
Gas pipeline system: Specially certified brass forged compression tees for gas must be used and meet strict specifications. The high reliability of forging is particularly important in such safety-critical applications.
Refrigeration system: Branch connection of refrigerant pipelines.
Ship and vehicle pipeline systems: Environments that need to withstand vibration and high pressure.

Pipe preparation: Critical. The cut must be straight, burr-free, and without depressions. Use a deburring tool to clean the inner and outer walls. The outer diameter of the pipe must strictly match the size of the joint. Oval or burrs on the pipe mouth are the main causes of leakage.
Sleeve and nut: Make sure the sleeve and nut are put on the pipe (put on the nut first, with the large mouth facing the body, then put on the sleeve), and then insert the pipe into the body socket to the bottom.
Hand tightening: Tighten each nut on the body by hand to ensure initial alignment.
Final tightening (key step):
Use two wrenches: one to fix the tee body (usually stuck on the hexagonal flat of the horizontal or vertical bar of the "T"), and the other to tighten the nut. It is absolutely forbidden to tighten the nut with only one wrench without fixing the body! This will cause the tee to twist, deform, or even crack.
Tighten the three nuts step by step in diagonal order. This helps to evenly distribute the force and prevent the body from twisting.
Overtightening will crush the sleeve or pipe, damage the joint or cause leakage. The goal is to create a seal, not "tighter is better".
Avoid stress: Make sure the connected pipes are well aligned and the pipe system should not subject the tee to bending or tensile stress after installation.
Pressure test: After the system is installed, a pressure test (usually 1.5 times the working pressure) must be performed to verify the tightness of all connections.
