Pipe Threading Tips
When threading pipe with a Steel Dragon Tools die head, or any die head for that matter, it is important to remember that the scale on the top of the die head i
s for reference only. The scale is used to get as close as possible to the correct threading size but it is up to the operator to test the die head, dies, and pipe.
Start by setting the die head to the desired threading capacity. Thread a sample piece of pipe and test the pipe with a c
orresponding fitting. A properly threaded piece of pipe will make one and a half to two full turns within the fitting before meeting resistance. A pipe that does not make one and a half to two full turns has threads that were cut too shallow. Shallow threads will not allow the pipe and the fitting to seal properly. A pipe that turns more than two full rotations in the fitting has threads that were cut too deep. A pipe with threads that are too deep may bottom out in the fitting, preventing the pipe and fitting from being tightened.
Pipe threading is not an exact science, it will take a little finesse and patience to successfully thread pipe and it is a good idea to test the threaded pipe on a regular basis. It is also important to remember that in most cases a sealant will be used on the pipe and fitting to prevent leaks. Using a sealant will allow the operator a bit of leeway when threading pipe.
The pipes themselves can also cause problems during threading. Pipes may not be true to their stated measurements. For example, a 1-inch pipe may be slightly smaller at 15/16 inches in diameter or slightly larger at 1-1/16 inches in diameter. The pipe may also be metric. A 25-millimeter pipe is slightly smaller than a 1-inch pipe but can look identical to the naked eye. Pipe variance must also be considered. Defects in the pipe from the manufacturing process can result in the pipe not being uniform from one end to the other. A pipe might measure 1 in. at the end, bow out to 1-1/16 in. at the middle before returning to 1 in. at the other end. It is always a good idea to periodically test the threaded pipe with a fitting to ensure a tight seal.

Different Types of Pipe
Steel Dragon Tools pipe threading machines can cut, thread, and ream a variety of different types of pipe with the right die head and dies. Some of the different types of pipe available on the market includes black iron, galvanized steel, stainless steel, copper, and plastic. Each pipe material has different uses and qualities.
Black iron pipe is made from mild steel. Black iron pipe is susceptible to corrosion when exposed to alkaline or acidic water. Black iron pipe is typically used for low-pressure and low-heat applications with gas or steam but is not suitable for potable water.
Cast iron pipe is manufactured with molds and is mostly used for sewage and waste removal. Cast iron pipe will corrode when in contact with carbonic or sulfuric acids. Cast iron pipe can be found in the sewage systems of many homes due to its durability and longevity. This type of pipe is popular for use in waste removal before of its thickness. The pipe’s density helps to muffle the sound of water and waste moving through it, resulting in a quieter home.
Galvanized iron pipe, also known as galvanized steel pipe, is steel pipe with a protective zinc coating. The zinc layer prevents rust and corrosion for approximately 40 years. Once the layer of zinc has been worn away, corrosion and deposits of salt and lime will eventually block the pipe. Galvanized pipe was used for potable water delivery but has been replaced with the more resistant copper and easier-to-handle PVC. Thanks to its anti-corrosion properties, durability, and relatively low cost, galvanized pipe is still popular for use outdoors in irrigation or in large construction projects where the amount of copper pipe needed might be cost prohibitive.
Stainless steel pipe is made with different alloys for use across many industries including food, aircraft and aerospace, nuclear energy, military, and medical applications. Stainless steel pipe is highly regarded for its low maintenance, corrosion resistance, hygienic properties, ease of fabrication, durability, and recyclability. Some types of stainless steel pipe are highly acid resistant and are typically found in chemical plants or for use in food processing.
Copper pipe is durable and corrosion resistant. This type of pipe is easy to handle and install but can be expensive. Copper pipe is typically used for potable water delivery and refrigerant lines in air conditioning systems. Copper pipe can also be used for gas delivery systems, both industrial and medical.
Polyvinyl chloride pipe (PVC) is a versatile material that comes in several chemical variations for different uses. This pipe can be used for pressure and non-pressure applications including potable water service, radiant floor heating, drains, waste removal, venting, irrigation, and ice melting. PVC pipe is inexpensive, easy to handle, and resistant to most household chemicals. PVC pipe does have a low resistance to heat and will expand rapidly when heated. PVC also has a lower pressure rating and crush resistance when compared to most metal pipe.
Steel Dragon Tools manufactures a variety of different pipe dies and die heads for use on the pipe material listed above. For more information on Steel Dragon Tools pipe threading machines, pipe dies, or die heads please click here or contact customer service here or by phone at 734-224-7112.

Replacing Dies In A Die Head
Replacing or installing new dies in the Steel Dragon Tools 811A Die Head is quick and easy. Lay the die head on a stable surface and move the handles to make the scroll inside the die head retract. The scroll holds the dies in place.
Once the scroll has retracted, slide the die into the die head. The scroll must be fully retracted to remove or install a die into the die slot. Each die is marked with a number and should slide into the corresponding die slot on the die head.
Push the die into the die slot up to the marked line on the top of the die. Once all four dies have been inserted, move the handle to re-engage the scroll, securing the dies in the die head. Some adjustment on each die may be needed if the scroll will not fully engage.
Wiggling the dies back and forth while moving the handle will usually remedy the problem. Once the dies are firmly in place, reinstall the die head onto the pipe threading machine.
Having multiple die heads with
different-sized dies can reduce work stoppage. Utilizing two die heads with different sets of dies will reduce the work load from switching outs dies when threading a variety of pipe sizes and materials. Simply remove the die head from the machine, install the second die head with a different die set, and continue threading pipe.
Steel Dragon Tools dies and die heads are interchangeable with compatible dies and die heads from a variety of manufacturers. Steel Dragon Tools die heads will fit compatible machines and will accept compatible dies. Steel Dragon Tools dies will fit compatible die heads as well.

The Common Traits of High-Performance Threading Oil
One of the most important elements when threading pipe, manually or with a machine, is the use of high-performance threading oil. High-performance threading oil is critical to producing straight and sharp threads when threading pipe. High-quality, professional-grade pipe threading oil from Steel Dragon Tools will facilitate perfect pipe threads every time.
Not all pipe threading oil is created equal. High-performance threading oil has four common characteristics:
1. LUBRICITY. The oil must have high lubricity to minimize load and reduce friction. Threading oil with high lubricity will reduce the friction between the dies and the material being threaded. Threading oil chemically bonds to the threaded surface and transforms into a metal film as dies cut away material. This metal film lowers the coefficient of friction and the load is reduced, resulting in threads that are straight and sharp.
2. HEAT ABSORBPSTION. Threading oil must absorb heat and immediately conduct it away from the threads. Excessive heat at the cutting surface leads to premature wear of the dies, metal chips welded on to the cutting edge of the dies, and torn, disfigured, or wavy threads.
3. ADHESION. Threading oil should cling to the pipe surface even in extreme temperatures. Oil with the proper viscosity will stick to the surface of the pipe during the threading process. This oil will transform into a metal film, reducing friction and absorbing heat as the pipe is threaded. The lowered friction and cooler temperature will result in straight and sharp threads.
4. CONSISTENCY. The viscosity and effectiveness of the oil must remain consistent throughout its operating life. High-quality threading oil will resist oxidation and will not have any volatile c
ompounds that can evaporate. The performance of the oil should remain effective throughout its life cycle.
With proper care, high-quality threading oil will never need to be changed. Threading oil only needs to be changed if the oil is contaminated with solvents, other oils, dirt, or grit. New oil should be added as needed to maintain the proper level in the oil sump of the pipe threading machine or the oiling bucket. Oil loss while threading pipe is common since 
the oil will stick to the threaded material.
High-performance threading oil from Steel Dragon Tools has high lubricity, and will absorb and dissipate heat immediately. Steel Dragon Tool threading oil easily clings to threading surfaces, and maintains a consistent viscosity throughout its operating life. Steel Dragon Tools threading oil does not contain PCBs, heavy metals, chlorine, or other halogens.
