U-bolt Mechanical Tee

Overview

The U-bolt Mechanical Tee is a modular pipe fitting created by assembling the upper housings of two mechanical tees. This configuration provides a flexible four-way branching solution for grooved piping systems. In specific installation scenarios, it can serve as an effective substitute for a traditional reducing cross, especially when ease of installation and system adaptability are required.

Product Description

A U-bolt Mechanical Teeallows a main pipeline to be divided into four directions through a mechanical clamping method. The fitting is mounted directly onto the main pipe, while the branch outlets are connected using grooved ends. This design eliminates the need for cutting, welding, or installing multiple fittings, offering a practical and efficient approach to complex pipeline layouts.
Different assembly combinations make it possible to accommodate equal or reducing branch connections, meeting diverse system requirements.

Installation Instruction For Threaded &Grooved Mechanical Tee

1.Take  out  the Rigid &Flexible Coupling Clean  the  gasket  sealing  surface within  16mm of the  hole and visually inspect  the  sealing  surface  for  defects that  may  prevent  proper  sealing  of  the gasket.Don't  drill  the  hole  on  weld line.		2.Split the Rigid &Flexible Coupling If any burrs or slug exists at the pipe hole,please   remove   them   before assembly,to  protect  the  gasket  and avoid   leakage.		3.Pipe preparation Insert  the  gasket  into  outlet  housing making sure the tab  in the gasket  line up with the tab  recesses  in the housing.Align   outlet   housing   over  the pipe  hole  making  sure  that  the locating  collar  is  in the  pipe  hole.			4.Lubricate gasket Align  the  strap  around  the pipe,inser the  bolts  and  tighten  the  nuts  finger tight.
5.Gasket installation Alternatively  and  evenly  tighten  the nuts  to  the  specified  bolt  torque.		6.Housing installation There should  be  even gaps on two sides  between  upper  and  lower housings.

FAQ

Q1: What is a grooved mechanical cross used for?
A: It is used to divide a main pipeline into four grooved branch connections using a mechanical clamping method.

Q2: Can it replace a traditional reducing cross?
A: Yes, in certain applications it can function as an alternative, depending on pipe size and system design.

Q3: Does installation require welding or cutting the pipe?
A: No. The fitting is mechanically attached, eliminating the need for welding or cutting.

Q4: Are different size combinations available?
A: Yes. Various configurations are possible, including equal and reducing branch arrangements.

Q5: Is it suitable for system modifications or expansions?
A: Yes. Its mechanical and grooved design makes it ideal for upgrades, retrofits, and maintenance work.
