Product Features of Galvanized Union Elbows

Galvanized pipe fittings refer to the treatment of galvanized pipe fittings. The base of the pipe and molten bath have complex physical and chemical reactions, forming a zinc ferroalloy layer with a close corrosion-resistant structure. 

The alloy layer is integrated with a pure zinc layer and pipe base. Therefore, it has strong corrosion resistance. The main purpose of galvanizing is to enhance the corrosion resistance of pipe fittings. Hot-dip galvanized pipe fittings are mainly used for conveying gas, heating, and other pipeline projects. If the steel pipe body needs to be galvanized anti-corrosion treatment, the corresponding connecting pipe fittings should also be galvanized. 

Applications of Male Seat Elbows in Piping Systems

Galvanized male seat elbows are widely used in various piping systems where durability, sealing performance, and corrosion resistance are essential. Common applications include:

● Industrial fluid systems – for oil, gas, and chemical pipelines.

● HVAC systems – reliable elbow joints for heating and cooling pipes.

● Water supply lines – efficient flow redirection in plumbing networks.

● Fire protection systems – secure, corrosion-resistant connections.

● Compressed air systems – airtight, threaded joints for industrial use.

● Agricultural irrigation – rust-resistant elbows for outdoor pipelines.

Their union and conical seat design allows for easy installation, tight sealing, and long service life across demanding environments.

The main production process of hot dip galvanized pipe fittings 

Degreasing → Rinsing → Pickling → Cleaning → Fluxing→ Hot air drying → Hot-dipped galvanizing → Cooling →Passivation and Rinsing.

Difference between hot dipped galvanized pipe fittings and electro galvanized pipe fittings

▶ Hot dipped galvanized pipe fittings:thick zinc layer, uniform zinc layer on the inner and outer walls, long service life.

▶ Electro galvanized pipe fittings:thin zinc layer, smooth and beautiful surface, lower cost, but inner surface zinc layer is too thin.
