How to correctly select and install malleable steel pipe fittings

Malleable steel pipe fittings, as an important pipe connection, are widely used in construction, industry, water conservancy and other

fields. It has the advantages of pressure resistance, corrosion resistance and wear resistance, so it is favored. However, due to the

wide variety of malleable steel pipe fittings on the market and the uneven quality, many people will encounter confusion when

choosing and installing. The following will introduce how to correctly select and install malleable steel pipe fittings.

1. Understand the types of malleable steel pipe fittings

Before choosing malleable steel pipe fittings, we must first understand its type. Common malleable steel pipe fittings are elbow,

three, four, reducing pipe and so on. Each type has different uses and characteristics, so choose the right type according to your

actual needs.

2. Check the product quality certification

When purchasing malleable steel pipe fittings, be sure to pay attention to the product quality certification. Regular manufacturers

will have relevant certification documents, and can be provided to consumers to consult. If there is no quality certification or the

certification is not clear, consider whether to buy the product.

3. Check the appearance quality

Appearance quality is also one of the important indicators to measure product quality. Good malleable steel pipe fittings have

smooth surface, no cracks, no bubbles and other defects. If you find these problems, you should consider whether to buy the

product.

4. Choose the right material

The material of malleable steel pipe fittings is also the focus of attention when choosing. Common materials are carbon steel,

stainless steel, alloy steel and so on. Different materials have different characteristics, such as corrosion resistance, strength, etc.,

to choose the appropriate material according to the actual use environment.

5. Pay attention to size and pressure level

When choosing malleable steel pipe fittings, pay attention to the size and pressure level. The size should match the diameter of the

pipe, otherwise the connection will not be tight; The pressure level should meet the actual use pressure, too high or too low will

affect the use effect.

6. Install malleable steel pipe fittings correctly

The correct installation of malleable steel pipe fittings can ensure its normal operation and extend its service life. First of all, ensure

that the pipe mouth is smooth and smooth, and remove rust and dirt; Then apply lubricant, in the installation should keep the axis

consistent, with a wrench properly tighten the nut; Finally, the tightness test is performed.

7. Check and maintain regularly

Although malleable steel pipe fittings have the characteristics of corrosion resistance, they also need regular inspection and

maintenance. Rust or damage is found to be replaced in time to avoid safety hazards.
