Black iron is a carbon steel without coating, giving it a distinctive dark appearance. It is not pure iron but steel with a specific amount of carbon. Black iron pipe is economical and durable. Galvanized steel is carbon steel coated with a layer of zinc to protect against corrosion. This additional coating makes it more suitable for water transport and outdoor applications.

According to different standards (ASME B36.10 or ASTM A733), pipe thickness is a key factor influencing pipe nipple property. Moreover, variations in thickness can lead to discrepancies in pressure ratings. A thicker wall can enhance resistance to external loads and internal pressures while providing better protection against corrosion and erosion in harsh environments.

DIN 2440 is Europe's industrial standard for carbon steel nipples suitable for low-pressure transportation and construction applications. DIN 2440 regulates the size, material, technical, and tolerance of seamless or welding pipes, common in gas, water, and other liquid transportation without corrosion.

Galvanized and stainless steel are popular in pipes and fittings, each with distinct advantages. Galvanized steel has a zinc coating that resists corrosion in damp conditions but struggles with high heat. Conversely, stainless steel, with its chromium content, excels in corrosion and heat resistance, making it ideal for food and medical uses.
