Ridgid

– USA

www.ridgid.com

Ridgid has been manufacturing and

selling tools to the pipe working and

contracting industry since 1923, when it

was founded in North Ridgeville, Ohio,

USA, to manufacture a revolutionary

style of heavy-duty pipe wrench.

Since then, the company has developed

into one of the world’s largest suppliers

of tools to the professional trades.

As time passed, the company expanded

its product line to include many other

tools. In 1943, growth was such that the

company had to move its headquarters

to its current facility in Elyria, Ohio.

Ridgid manufactures over 300 different

tools in more than 4,000 models and

sizes, ranging from the original Ridgid

pipe wrench to pipe/tubing tools,

pressing tools for joining copper tubing,

pipe and drain cleaning equipment and

the latest diagnostic inspection and

locating tools.

The company’s products are distributed

on six continents and in more than 155

countries. Markets are served from a

125,000ft

central distribution facility in

central Ohio. Other stocking warehouse

locations include Europe, Canada,

Central and Latin America, Australia,

the Middle East, Japan, the Far East

and Africa.

Ridgid products are sold to end users

through professional tool distribution

and large retail channels. In the USA,

Ridgid tools are available at over 4,000

distributor locations.

The company manufactures products

on three continents to serve the world

market. The main manufacturing facility

and world headquarters are in Elyria,

Ohio, where pipe working products are

produced. Other US manufacturing

facilities are located in Erie, Pennsylvania,

and Orange, Virginia. Overseas

manufacturing facilities include Sissach,

Switzerland; Gevelsberg, Germany; Cluj-

Napoca, Romania; and Shanghai, China.

Step 7: Ream the pipe

Reaming of steel pipe is required by code. Removing

the steel burr (created when cut by a pipe cutter)

on the inside diameter of the pipe allows for

unrestricted flow of fluids, steam and wires that may

be intended to go through the pipe.

To begin the threading operation, ensure your

die head has the corresponding size of dies for

the diameter of pipe. Next, set your die head to

accommodate this size. As a reminder, threading

to 2" pipe requires four sets of dies:

TPI. The ream is completed

when you see the burr has been removed.

Step 8: Threading the pipe

To begin threading, pull the die head down so it sits on the

carriage. Prior to advancing the die head, start the machine

to begin rotating the pipe in a forward, counter-clockwise

direction. Next, advance the die head to the rotating pipe.

Apply pressure after the throat of the dies makes contact with

the end of the pipe. Note: the dies are designed to engage the

end of the pipe at this point. That is what allows you to cut the

thread under the power of the rotating pipe.

A standard-length thread is typically completed when the

last tooth on the dies comes flush with the end of the pipe.

This will give you a standard length of thread, allowing you

to manually thread on a coupling (approximately three turns,

using a pipe wrench to tighten completely).

As a special side note, it is important that you use quality

thread-cutting oil when threading. Not only will it lubricate

the pipe, allowing for the dies to cut through the material

with greater ease, but it will also perform a flushing function,

moving chips away from the work to minimise torn threads.

Additionally, threading oil ‘cools the work’, keeping dies from

heating up during metal-to-metal operation.

Finally, if threading various material types, it is important

that you use the best oil for the operation. Motor oils, lathe

coolants and water are not suitable for threading.

Step 9: Cutting the pipe

Once the pipe is threaded, cut the pipe to your desired length.

To do so, make sure the pipe is not rotating, then pull the pipe

cutter down on the carriage and place over the pipe. Close

the cutter wheel up to the wall of the pipe and begin rotating

the pipe forward. Once the pipe is moving, advance the cutter

wheel until it breaks through the inner wall of the pipe. (Note:

Do not stop rotating the pipe until the cut has been made

completely through its wall). Once the cut has been made, you

are ready to perform the next task on the uncut end.
