What Are Swivel Joints?


Swivel joint is a rotational piping joint to performs rotary motion or linear motion in the vertical, horizontal, or forward/backward directions when fluid/gas is transported in pipe line.

360 degrees rotation achieved by comnibation of two row ball bearings and two components, which allows for free movement of pipes while fluid transportation.

TBG manufactures TB-NIIGATA swivel joints for a broad range of process machinery in the chemical, petroleum, aviation, refining, mining, steel, bevarage, paint, as well as daily food, pharmaceutical industries.


What is the diffrence with Rotary Joints ?

A rotary joint is a joint that can form a flow path for water, air, oil, etc., between a fixed pipe and a rotating shaft.

It is sometimes called a rotary joint or rotary union.
Rotary joints make it possible to supply fluid continuously to a rotating body and circulate the fluid inside.

This function can be used to add functions such as cooling and lubrication to the rotating rolls or to supply power source fluid to equipment on the rotating body.

• By attaching it to the base of an existing hose, it prevents the hose from being twisted or damaged.

• It is easier to change the outflow direction and route the piping without loosening clamp band .

• Since the hose length and bending radius can be reduced, a compact design is possible, and the piping layout can be easily changed.

• There is no need special tools to assemble and disassemble, which leads to labor-saving.

Roof Drain System for Floatin Roof Tanks
(Conventional)

Niigata floating roof tanks draining systems have a record life expectancy of more than 30 years in operations without significant issues or accidents occurrence.

Their market share is nearly 100% in Japan.

Niigata draining system assembly design allows for permanently stable positioning of the drain inside the tank without possible interference with the floating roof legs when the tank is empty, guaranteeing no mechanical damage of the drain and no abrasion of the tank floor like hose drains would, as a result as not being guided inside the tank.

Roof Drain System for Floatin Roof Tanks
(Single Line)

TBG developed a more economical system using only four doubel seal joints for submerged service for minor drainage tanks or tanks with a smaller roof surface.

Construction

Willow

As a moving pipe, it is more rigid than a hose and can handle even the largest variations by simply changing the pipe's length. It can be installed in a small space because its length is extremely short in relation to the required displacement, which is typically a problem for high-pressure hoses.

Our hoses are made of steel pipes and have a specially coated sealing material to ensure high durability and pressure resistance. Steel pipes minimize the risk of rupture, making them exceptionally safe for use in high-pressure fire-extinguishing piping.

Example Fluids:
•Domestic wastewater, air, N2 gas, CO2 gas, LP gas, CFC,halon, etc.
• Oil-based systems such as kerosene and light oil, NH3, etc.
