Overview of Piping Systems for Steel Pipe Fittings

(1) Overview of piping system for steel pipe fittings such as Barred Tees

In order to transport liquids or gases, various pipes must be used. In addition to the steel pipes for straight pipes, various pipe fittings are used: elbows are required when the pipe is bent, and the head is used when the pipe is tapered. To use the tee, the pipe such as Reducing Tee joint should be flanged when connecting with the joint. In order to achieve the purpose of opening the conveying medium, various valves are also needed. In order to reduce the impact of thermal expansion or contraction or frequent vibration on the pipeline system, expansion is also required. In addition, in the pipeline, there are various joints, plugs, etc. connected with various instruments and meters. We are used to refer to other parts of the piping system other than straight pipes as pipe fittings.

(2) Common sense of metal materials for steel pipe fittings such as Straight Tee:

Metal materials are widely used in our daily life and industry. They are mainly divided into steel, iron and non-ferrous metals, and the steel is more commonly used. The main component of steel is iron. The rest is artificially added alloying elements and various impurities. It is precisely because of the different types of these added alloying elements that a variety of steels are formed, such as ordinary carbon steel, stainless steel, alloy steel, etc. Among these added elements, carbon C plays a very important role.

How is The Radius of The Pipe Elbow Calculated?

The “radius of the pipe elbow” such as 45° Elbow should be changed to the bending radius of the pipe, which is usually set by the diameter multiple of the pipe. It has no calculation.

There is no uniform standard for formulas. If the bending radius is small, the local resistance generated by the fluid in the pipeline will be large, such as a large bending radius, resulting in a large installation space, and the manufacturing cost of the corresponding elbow is also high. The elbows of the pipeline are: the elbow casting elbow in the tanning pipe (water gas pipe) (the bending radius is small, and the pipe diameter is not strictly proportional to the diameter, generally less than the 1D pipe diameter, but its size is standard); steel Pressing the bend (the bending radius is small, generally equal to 1D slightly more, there are two kinds of national standards, the so-called big bend and small bend, there is no strict rate relationship with the pipeline); tangent bend (for seamless steel pipeline, in chemical industry Pipes used to be used in the past, especially on high-pressure pipes,such as Alloy Steel Bend which are basically used for bending, whose design requires a bending radius of more than 6 times the diameter of the pipe); corner bends (for high-pressure pipes, oil circuits, which are calcined) Made, directly punched, no bending radius at all); there are also shrimp bends (welded, the bending radius is generally about 1 ~ 1.5, the country has "steel parts" atlas, but in fact, Usually made by the producer.

Cast iron pipe elbows, Seamless Elbow the country has standards, and its bending radius is also very small; plastic pipe elbows, there are industry standards, the bending radius is also small; soft bending is a special elbow; bending radius is freely variable .

5 Tips for Pipe Fitting Project

Before making final decisions and adjustments pipe fiting such as 45° Bend, Please checking all can allow you to avoid this stressful situation.

（1 ）Practice Before the Setup

Like the preceding suggestion, this will help you dodge a costly error. Do a test. Knowing what you are doing in advance will make the whole project go.

（2）Do not Tighten Too Much

pipe fitting such as Seamless Elbow Overtightening when screwing fittings together can cause difficulties with your components and really create your pipes more likely to leak. Rubber seals are made to keep your pipes watertight -- let them do not hurt them and do their job. Employing plumber's tape can help you keep an proper level of tightness.

（3）Be Careful With the Threads

If you strip the threads on your fittings such as Seamless Tee, they will be quite hard or even impossible to utilize later on. Avoid doing so and spare yourself the trouble of a flow in the future.

（4）Don't Be Afraid to Get Help

It is better to bring in outside help than risk the frustration of a pipe fitting job gone wrong. Let a professional take over if you are unsure even after training. When your pipes are back to normal, you'll be thankful.
