Since ancient times, steel has been considered the best material for manufacturing pipes and fittings. The properties of steel - durability, high strength and high heat resistance - make it ideal for pipes and fittings. 


Steel pipes and fittings are used for domestic and industrial purposes. Steel pipe fittings are often mixed with other materials to increase durability and provide better rust resistance. The most common varieties of such steel pipe fittings used are - galvanized steel pipe fittings, carbon steel pipe fittings and stainless steel pipe fittings. Next, the pipe fitting supplier will share the following content with you.


Galvanized steel fittings and their applications

Through a chemical process, a layer of zinc is applied to the steel. This type of pipe is highly resistant to corrosion and is therefore ideal for manufacturing pipes and pipe fittings. The zinc coating increases the service life of the fittings. They are usually made from seamless tubes or forgings under specific standards. They are available in sizes ranging from 8 mm to 150 mm and are used for pipelines and water lines in buildings, but not for natural gas pipelines.

How do fittings connect to pipes?

You can find two types of fittings, female fittings and male fittings. Female threads are located on the inside of threaded fittings. Street fittings are those with male and female ends. Tubes and pipes can be connected using fittings in two ways.

Threading

Threaded tubes are screwed together to join them. In most cases, metal pipes have threaded fittings.

Slip-Fit

Casing is used with sliding-fit tubes, which slide over each other. Usually, plastic tubes are sliding fit, but they can also be threaded.

What criteria should I consider when selecting fittings?

There are a number of factors to consider when selecting fittings.


Type of connection

When you start buying fittings, you must keep in mind that there are two types of connectors. Maybe one end is female threaded and the other is female threaded. Or when you're talking about plastic fittings, one end is male ferrule and the other is threaded. In addition, they are available with matching ends to meet all requirements.

Materials of Construction

It is common that the fitting material should be the same as the material used for the pipe. However, sometimes certain materials can be used for pipes made from any material.

Check its flow

The end of the tubing should be made larger than the rest of the fitting to keep it flowing consistently. It will help accommodate the connection without damaging the inside diameter of the pipe.

Type of tubing

In addition to the material of the pipe, the type of fitting should be noted, including threaded or sliding fittings and male or female fits.

Size

Fittings are sized differently on the outside and inside ends. For male threaded fittings, the outside edge of the fitting is measured, while for female threaded fittings, the size is measured from the inside edge of the inlet.

Design

Different pipes are designed to carry different fluids such as gases, liquids or chemicals. Depending on the use of the pipe, a variety of fitting designs are available.

Thickness

Fittings are also available in the same different thicknesses as the pipe.

Codes and Standards

Various organizations have developed different standards based on the classification of fittings. Some of the standards associated with fittings are ASTM, BSP and ASME. If you want to know about the wholesale best pipe fitting price, welcome to contact us.
