SS 304 Elbows Dimensions

SS 304 elbows are pipe fittings used to connect two sections of pipes to change the direction of pipes and water pipe systems. Common angles are 45°, 90° and 180°. Due to the excellent corrosion resistance, high strength and durability of stainless steel, they have a wide range of applications. They are commonly found in petrochemical, chemical, pharmaceutical, food and other industrial fields.

Due to the excellent corrosion resistance of stainless steel, structural components can maintain the integrity of engineering design. Chromium-containing stainless steel also combines mechanical strength and high ductility. It is easy to process and manufacture components and can meet the needs of architects and structural designers. Stainless steel elbows will not cause corrosion, pitting, rust or wear. Among building metal materials, stainless steel is still one of the high-strength materials.

ZIZI offers various styles and sizes of stainless steel elbows, elbow sizes range from 1/2 inch to 80 inches. It wall thickness range covers SCH 10, 20, 40, STD, XS, 80, 100, 120, 140, 160, XXS in accordance with ASME B16.9 standard.

How to Get Accurate Size Information?

To get specific SS 304 elbow size, you need to:

Determine the nominal diameter (NPS/DN): Choose the appropriate size according to your piping system.

Determine the elbow type: 90 degree long / short radius, 45 degree long radius, 180 degree long radius, etc.

Determine the wall thickness grade (Schedule): This is closely related to the pressure grade of the pipeline.

Check the corresponding standards: Check the corresponding A standard chart according to the project requirements.

Contact the supplier: ZIZI, as a stainless steel pipe fittings supplier, will provide a detailed product size table. We can also provide customized information according to your needs.
