Malleable Iron Black Hexagon Nipples

Malleable iron black hexagon nipples have better tensile strength and wear resistance than traditional iron connectors because it is made of malleable iron material. At the same time, the hexagonal threaded connection end design ensures the tightness and solidity of the connection, which means that it has high sealing performance and can effectively prevent leakage and contamination of liquids, gases and other media. This nipple has high temperature resistance and corrosion resistance, and can withstand temperatures up to 200°C, so it can adapt to complex industrial environments. In pipeline systems in petrochemical, food processing, construction engineering and other industries, it can ensure the tight connection and safe operation of pipelines. We can also provide cast iron materials of B330-6 and KTH330-6 models for your choice.

• These malleable iron black hexagon nipples are UL/FM certified, so they are extremely safe and reliable.

• After hot-dip galvanizing, these nipples gain better corrosion resistance to resist corrosion from pipeline media such as gas, water, steam, and oil.

• This nipple connects pipes via male and female threaded connectors, including NPT or BSPT in various sizes and shapes.

• The smelting of these nipples is carried out using electric furnaces, which provide a more stable process compared to traditional cupola furnaces. Therefore, the quality of these products is more reliable.

• These nipples are designed and manufactured strictly in accordance with standards such as EN10242/ANSI/ASME B16.3/DIN2950/IS0 49, which means they are compatible with most accessories and standard sizes on the market. If needed, we can produce according to other standards required by customers.

Design:

These malleable iron black hexagon nipples are available in various sizes and designs, such as DN6-DN150, to meet the usage requirements of different scale piping systems. They have a hexagonal shape and can be easily tightened with a wrench, ensuring a safe and stable connection.

Versatility:

The black oxide coating of these nipples not only improves the aesthetics, but also enhances rust resistance. This coating is very durable and can adapt to complex application environments such as high temperature and humidity. It’s also available in a matte finish.

Cost-Effective:
