Cast basalt lined steel pipe

Product Specification

Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.

Specification

• Nominal Bore: 32 to 600 mm
• Thickness Ranging: 20 to 30 mm
• Length: 500 mm

It combines the advantages of cast basalt and steel pipe, wear resistance, corrosion resistance, anti-high-pressure, transportation and easy installation. Water transport in plant ash and metal mine tailings pipeline hydraulic conveyance system appling this product can life up to 30 years. Cast basalt lined steel pipe is divided into straight tube, elbow, tee, reducer pipe.

Cast basalt lined steel pipe is consist of steel pipe, cast basalt pipe and the concreteness of cement mortar.

According to customer requirements along with cast basalt production technology and we can offer various specifications and various shape to meet client's need.

• Friction Resistance: As more material is passed over Cast Basalt it gets polished up thereby reducing friction further. Cast Basalt improves in service after getting polished. Wetting also improves its performance in practical applications.
• Impact Resistance: Direct Impact Resistance at 90 degree is low like all other ceramics, but it can be increased with proper installation by reducing the angle of impact. Cast Basalt is the best wherever sliding abrasion exists. Moreover, external impact strength of composite basalt pipe is always more than that of bare Ni-hard Pipe.
• Chemical Resistance : Cast Basalt is almost absolutely acid/alkali resistant (except Hydrofluoric Acid) and hence corrosion resistant.
• Weight and Sizes: Basalt Tiles are available in regular shape square of 200 x 200 x 30 mm thick, weighing approx. 90 kg/sq m; whereas bends and pipes are lined using Basalt Cylinders of various standard sizes from 50NB upto 500NB.
• Temperature: Cast Basalt withstands temperature up to 4500oC

Cast basalt lined steel pipe is made with lined cast basalt pipes, coat steel pipe and the cement mortar filling between the two layers, it sets the wear resistance and corrosion resistance of cast stone pipe, the toughness of the steel pipe and the consolidation of the cement mortar in one. Greatly improve the product's ability of adapting various complicated working condition. At the same time using cement mortar as filling material, can make the pipe inner surface in alkaline medium, so that the surface of the steel pipe will produce a purified film to prevent corrosion. Cast basalt lined steel pipe is not only resistant to wear and corrosion, against high pressure, but also convenient and safe to transport.

The nominal diameter series of cast basalt lined steel elbow pipe is the same as the cast basalt lined steel straight pipe , the turning radius and central Angle can be made according to the requirements of customers.

The technical parameters of the coat steel of cast basalt lined steel pipe according to the operating pressure of the pipeline system to determine.
