What is the key?

The pipe key is an aluminum or steel tool used for grip and then tightening or release of rounded metal objects such as screws, pipes or bars. The pipeline is made of jaw with upper hook and lower jaw heel connected to the flat handle. The jaw pieces have small teeth or grooves for grasped rounded objects when it turns, and the lower jaw can be set either up or down to fit the size of the metal object. Pipe keys come in different sizes and types.

This type of key should not be used on hard metals such as steel or square objects, as the teeth of the keys can cause the surface damage. It should also be between the back of the jaw hooks and the surface for the correct amount of grip to be applied and to prevent damage to the object, key or person. If the tubular key is damaged, also called the Stillson key, you can repair the purchase of teeth and jaw set.

There are three main types of pipelinesES: Straight, offset and end tube key. Other key types include folded lever key, chain pipe key and strap key. Each of these tools has its own unique purpose and specification.

The direct key is the original piping key designed by Daniel C. Stillson in 1869. The direct key is the most popular key for general purposes and is an essential part of any set of tools. The keys are measured by the length of the handle and a straight key can be purchased in sizes ranging from 9 to 60 inches (about 23 to 152 cm).

The

offset key is designed to be used in tight spaces where there is little or no space for swinging the keys. They are also useful for turning objects that are at an unpleasant angle or when the pipe is parallel to another object. The jaw on the offset hook is placed parallel to the key handles and lifelong jaws.

the end tubular key is used on a chica hundred pipes that are close to the wall or where they change the direction of the pipeline. The jaws and heels of the keys are at a slight angle to the key handle, which makes this tool very useful in tight spaces. The end key can also be useful in working on ceiling pipes.
