Cement Lined Steel Elbows ASME B16.9 Pipe fittings AWWA C205 Cement Mortar Lining

We are a professional manufacturer of Cement Lined Steel Elbows ASME B16.9 Pipe fittings in China

Cement-lined steel elbows are commonly used in industrial applications, especially for transporting abrasive or corrosive materials through pipelines. The lining of cement (often a mixture of cement and sand) provides a protective layer inside the steel pipe, helping to prevent corrosion and wear from the flow of materials like slurry, chemicals, or wastewater.

Cement lining is a process by which steel pipe and fittings are coated internally with cement mortar. This process combines the physical strength of steel with the protective qualities of cement mortar. 

Internal cement-lining of pipesystems protects the inner steel surface from corrosion and provides excellent hydraulic properties.

We can supply the steel pipe fititngs,elbow Cement Lined according to AWWA C205 standard,

Cement-lined steel pipes are used in various industrial applications, particularly for water, wastewater, and other fluid transportation systems, due to their resistance to corrosion and wear.

Product structure:

• Steel Elbow: The base material is typically a high-quality steel, which provides strength and durability.
• Cement Lining: A thick layer of cement is applied inside the elbow to protect against internal corrosion, erosion, and abrasion caused by the flow of materials.

Pipe fittings Material can be use for Cement Lined Steel pipe fittings ASME B16.9

Cement–Mortar Protective Lining and Coating for Steel Water Pipe—4 In. (100 mm) and Larger—Shop Applied

Cement–mortar-lined and cement–mortar-coated steel pipe combines the physical strength of steel with the protective qualities of cement mortar. The lining, applied centrifugally, creates a smooth, dense finish that protects the pipe from tuberculation and provides a measure of corrosion protection. The smooth interior surface provides a high flow coefficient for the design life of the pipeline under normal operating conditions. In addition, the cement–mortar coating results in a tough, durable, and rugged coating that forms an alkaline environment where oxidation or corrosion of the steel is inhibited.

Application of Cement Lined Steel Pipe fittings Elbows

• Slurry Pipelines: Used in mining and power generation where the flow of abrasive slurry is common.
• Chemical Industry: For the transport of acidic or corrosive chemicals where traditional steel might corrode.
• Wastewater and Sewage Systems: Cement-lined steel elbows are used in wastewater treatment plants to handle corrosive and abrasive materials.
