The choice of pipe cutting machine can be viewed from the following aspects:

1. Depending on the material to be cut, shape (round tube, square tube, bar, or special shape), Dimensions and thickness of materials, Cut straight or diagonally 45 degrees to choose different size models.

Different types of pipe cutting machines can process different sizes of materials;

Different materials require different power of pipe cutting machine;

The same pipe cutting machine, its 45 degrees of cutting material size is often smaller than 90 degrees of cutting;

Generally speaking, for relatively small iron pipe, copper pipe, in the cutting accuracy is not high, blanking output is not large can choose manual type or low-power semi-automatic pipe cutting machine.

2.According to the blanking accuracy requirements or quality requirements to determine.

If the blanking accuracy requirement is high, the output is large, the specification of the cutting material is large or thick, then we need to consider the automatic pipe cutting machine or the high-power semi-automatic pipe cutting machine.

Generally speaking, manual pipe cutting machine, semi-automatic pipe cutting machine and automatic pipe cutting machine all have the following characteristics:

Manual cutting machine: feeding, clamping and cutting are manual operation, mainly for some cutting requirements are not high, the efficiency is not high, and the cutting amount is not large occasions.

Semi-automatic pipe cutting machine: manual feeding, clamping and cutting are all automated operations, mainly for some occasions with high efficiency requirements, low length accuracy requirements and large cutting quantity.

Automatic pipe cutting machine: feeding, clamping, cutting are automatic operation, mainly for some high efficiency requirements, there are certain cutting precision requirements, and the cutting amount is also large occasions.

In the selection of pipe cutting machine, taking into account the above factors, I believe you can choose a suitable pipe cutting machine for your product.

Here we talk about automatic pipe cutting machines.

Generally speaking, for relatively small copper pipe, diameter less than 50mm, our YE-Q1 is very suitable; Bale cutting, will not cause cutting deformation because of thin wall.

If cutting relatively large copper pipe, aluminum pipe, diameter less than 120mm, it is recommended to consider our YE-Q2 pipe cutting machine. Bale or single cut, efficient and can ensure precision.

End caps for electrical wires are often called wire caps or wire nuts.  

Whatever you call them, electrical caps are an essential supply for any wiring job.

The most common type are screw-on connectors, but push-on connectors are also available.

The most important thing to remember when purchasing or using wire caps is to select one that is large enough to accommodate the wires you are joining.

The wires should all be the same gauge.

The electrical code doesn’t permit connecting different size wires in the same circuit.

Size Wire Caps by Manufacturer’s Specifications, Not by Color

Screw-on wire caps are conical and made of plastic, often with ribbing or wings to make them easier to grip.

Inside, at the narrow end of the cone, a threaded conducting metal grips the ends of the wires you want to join and twists them together when you screw the cap clockwise.

Push-on connectors are similar, but instead screw threads, they feature a locking mechanism that holds the wires securely.

All you have to do is push the wires into the connector openings.

When you shop for wire caps, you’ll see a rainbow of colors, and they appear to conform to a color scheme that indicates which wire gauge they are for.

While this scheme does apply to a point, you can’t rely on it, because there are no standards that govern it.

Instead, you should check the label on the container for the manufacturer’s wire gauge recommendations.

If you want to use a large nut intended for heavy gauge wire to connect several smaller-gauge wires, you should check the specifications for the maximum wire diameter the connector is designed to hold.

To Twist or Not to Twist?

Before connecting wires with a wire cap, strip about a half inch of insulation from the end of each wire to be joined.

Use a wire stripper for this.

It’s cleaner and easier than using a knife.

Straighten out the stripped ends of the wires and hold the wires together so the ends are parallel.

Slip the cap over the ends and screw it on.

Keep tightening until the visible, insulated wires outside the cap begin to twist together, which means that the bare wires under the cap are as tight as they can be.

Many electricians add one more step to this procedure.

They twist the wire ends together with pliers before screwing on the cap.

This provides insurance against separating, and is recommended.

If you do twist the wires, twist them clockwise.

If you go the other way, the wire cap will actually loosen the wires when you screw it on.

Safety Considerations When Using Wire Caps

As is true when you’re doing any electrical work, it’s important to turn off the power before you touch exposed wires.

Keep a voltage tester handy so you can test each wire individually.

Strip just enough wire to fit inside the cap.

No exposed wire should be visible outside it.

If there are exposed wires, it’s safer to redo the connection than to cover the cap with electrical tape, but tape is always an option.

Use waterproof wire caps whenever doing exterior or underground wiring.

These are usually filled with silicone sealant and, unlike interior wire caps, are not reusable.

Connect stranded and solid wires by extending the end of the stranded wire about 1/8 inch past the end of the solid one.

That way, when you screw on the cap, the stranded wire will bond securely to the exposed end of the solid one and not to the insulation.

Solder is commonly used to attach wires and other electrical components by melting a small amount of conductive material to secure the connection.

What do you do if you don’t have access to solder or soldering equipment, though?

After all, you can’t exactly use super glue instead of solder to join a wire.

Any joins you make need to preserve the conductivity of the wire and hold up to heat and oxidation.

Fortunately, there are ways to join wires without the need for solder that is both safe to use and just as effective.

There are a number of reasons why you might need to join two wires.

Whether you’re dealing with a piece of wire that simply isn’t long enough to meet your needs or you need to connect two wires to complete a circuit, it’s important that you find a way to join the wires without creating a safety hazard.

If you can’t use solder to join your wires, a splice that winds the wires together will get the job done just as well.

Be sure to strip enough insulation from the wire to allow for several twists between the two pieces of wire.

The best way to splice wires is to wrap them together tightly, using multiple twists to ensure maximum contact between the two wire sections.

There are multiple techniques for splicing wires without solder that result in a tight wrap, including some that overlap the wires before twisting to give a larger overall spliced area.

If you need an easier way to connect two wires, wire caps, terminal connectors are commonly-used splicing components.

The wire caps work by twisting two wire ends together tightly, holding them close beneath the cap so that they cannot break their contact.

Terminal connectors work similarly, placing the wires together and then closing the connector over the joined ends.

The terminal connector or wire cap itself serves as a sort of insulation, covering the splice with plastic so long as the cap is in place.

When using a wire cap or terminal connector, only a small amount of wire insulation needs be removed before splicing.

Regardless of the method you use to join your wires, it’s important that you insulate the wires properly afterward.

This can be done with electrical tape or insulation wraps, as well as shrink-to-fit insulation sleeves that you fit over the join and then apply heat to shrink. 

Crimping is a style of joining wires to metal fittings that are then used to connect the wire to another wiring component or to other wires.

The fittings themselves come in various styles, and are collectively known as “crimp connectors.”

They are most commonly used with stranded wires found in the wiring of appliances, electronics, or automobile systems.

The technique involves compressing a small insulated metal sleeve on the end of the connector around the exposed bare wires.

Wire connections using crimp connectors are often used in locations where the heat of soldering is not appropriate, or where the wire connection may need to be detached occasionally.

Connections made with crimp connectors take up little space; they also are easier to make than solder connections and when done properly, they can be just as effective.

When you crimp a connector onto the end of a wire, the idea is to form a tight, continuous electrical union between the wire and the connector fitting that will stay together permanently.

To achieve this, both the connector sleeve and the wire both have to be malleable enough to deform under a compressive force.

An electrical connector is a device for joining electrical circuits together using a mechanical assembly.

The connection may be temporary or serve as a permanent electrical joint between two wires.

There are hundreds of types of electrical connectors.

Connectors may join two lengths of wire together or connect a wire to an electrical terminal.

Crimp connectors work best with stranded wire because solid wire usually isn’t malleable or ductile enough to make a reliable connection.

The wire gauge isn’t a major factor.

You can crimp a connector onto beefy 8-gauge wire as effectively as you can onto 18-gauge wire, as long as you use a connector of the right size.

Below area few connector types.

On the far, upper left, we have an insulated splice connector to connect two wire ends together.

To the right, the forked connector (spade, or split ring) is useful for connecting wire to screw terminals by sliding the fork into a screw terminals’s socket.

Screws can be partially screwed in before installing the terminal.

The ring terminals in the middle are also useful for connecting wire to screw terminals.

While the ring terminal provides a more reliable connection, you would need to completely remove the screw before installing the terminal.

On the far, upper right we have a male spade connector (blade).

These can slide into the female spade connector (double crimp) that is shown on the bottom right.

Depending on the design and application, these connectors can come in different flavors like flanged fork or locking ring terminal.

To achieve the necessary compressive force, it’s best to use a crimping tool when attaching crimp connectors to a wire.

Pliers or a hammer will work in a pinch, but using such tools can result in a loose connection that ultimately results in an open circuit.

Nothing is more difficult to diagnose than a loose crimp connection in complex automotive and appliance electrical systems, where crimping is most commonly used.

Choose the Right Connector

Crimp connectors come in many styles, so make sure you choose the right one for the application.

• A ring connector makes the most secure connection to a terminal post. It can be disconnected only if nut on the terminal is removed.
• A spade connector is best for situations in which it’s impractical to remove the nut from the connection terminal. The spade-shaped tip slides into a socket on the terminal.
• A quick-disconnect connector can be barrel-shaped or blade-shaped. You can separate the connection by pulling the two halves apart.
• A butt connector permanently splices two wires together.
