Black pipe nipples are threaded iron/steel pipe nipples forged from high-quality carbon steel pipes after coating or sandblasting. Black steel pipe nipples are sandblasted or coated with anti-corrosion coating for increasing the corrosion resistance of the steel pipe nipples and prolong the service life. Hebei Sanvo is a professional carbon steel nipple manufacturer and supplier in China and customizes carbon steel and stainless steel pipe nipples. Among them, the black pipe nipples include seamless pipe nipple, welded pipe nipple, TOE pipe nipple/welding nipple, TBE pipe nipple/barrel nipple, close nipple/running nipple, and shoulder nipple.

Black pipe nipples are made of black carbon steel pipe made of steel that has not been galvanized. Their name comes from the scaly, dark-colored iron oxide coating on its surface. The surface of the SANVO black pipe nipples is oiled or sandblasted to prevent corrosion. They are used in applications that don't require galvanized steel.

Determining what size pipes you need for your project can be confusing. Many people assume pipe size is the outer diameter of the pipe—but “pipe size” actually refers to what is called “nominal diameter.”
Fittings can be just as confusing. Their inside diameters must be large enough to fit over the pipe's outside diameter. A half-inch steel elbow, for example, has an outside diameter of about 1-1/4 inches.
The easiest way to find what nominal pipe size you need is to use follow these steps.

The primary differences between black nipples and galvanized nipples lie in their materials, coatings, and applications:
Black Nipples: Made from uncoated carbon steel. They have a plain finish without any protective coating.
Galvanized nipples are made from carbon steel and coated with a layer of zinc through galvanization.
Black nipples are more susceptible to rust and corrosion because they lack a protective coating. They are suitable for dry indoor environments.
Galvanized nipples are Highly corrosion resistant due to the zinc coating, making them suitable for outdoor or humid environments where moisture is present.
Black Nipples are suitable for low-pressure gas and oil lines. They are fit for places where they won't get wet.
Galvanized Nipples: Ideal for water plumbing applications, especially outside or wet environments and heating systems.
Black Nipples characteristically have a dark, matte finish.
Galvanized Nipples have a shiny, metallic finish due to the zinc coating.
In summary, black nipples are suitable for specific applications with minimal exposure to moisture. Galvanized nipples get a lot of attention in building trades and water lines because of their strength and ability to resist rust in wet conditions.
