Comparing Black Steel Fittings And Galvanized Iron Pipe Fitting

by | Apr 27, 2023 | News

Black steel fittings and galvanized iron pipe fittings are two of the most common options for joining iron or steel pipes. Each has its pros and cons. So let’s compare them to determine which is better for your particular plumbing or mechanical application.

About Black Steel Fittings From China Manufacturer

China Black steel fittings are made of plain carbon steel that has not been galvanized or coated. They tend to be less expensive than galvanized iron pipe fittings. However, the lack of galvanization means they are more prone to corrosion, rusting, or deterioration over time when exposed to moisture or high-humidity conditions. They require more maintenance and may not last as long. Meanwhile, Black pipe fittings could refer to many types, Today, I will introduce the black pipe cross tee.

Example of black steel fittings – pipe cross tee

A black pipe cross tee is a type of plumbing fitting that is used to connect four pipes together at a right angle. It is called a black pipe cross tee because it is made from black steel, which is a type of carbon steel that has been treated with a black oxide coating to protect against rust and corrosion. This coating also gives the fittings a matte black finish, which is why they are commonly referred to as black steel fittings.

Galvanized Pipe Fittings

Galvanized Iron Pipe Fittings With Related Detail

Galvanized iron pipe fittings have been coated in zinc, which protects the base metal from corrosion. The galvanized coating is durable and long-lasting. Galvanized fittings tend to be more rust-resistant and maintenance-free. However, the galvanization process also makes the fittings more expensive. The zinc coating can also eventually flake or fade over many years of use.

Some Key Factors To Weigh When Choosing Between These Options

  • Galvanized will be more corrosion-proof, especially for high-moisture uses. Black steel is more susceptible to rust and deterioration.
  • Black steel fittings are typically the most affordable upfront. Galvanized fittings cost more due to the added zinc coating process.
  • Galvanized fittings can last longer overall due to the protective zinc coating. With proper care, both can last a long time but galvanized may edge out black steel fittings.
  • Both black steel and galvanized iron pipe fittings are similar to use for joining and connecting pipes. No significant differences here.
  • Galvanized fittings have a silver-gray finish, while black steel fittings have a standard steel finish. Galvanized may be more attractive for some applications.
