Precautions

1 metal-ceramic composite pipe high hardness, good toughness, but in the handling, installation process moving light to light , to avoid serious collisions, in particular to avoid direct metal instruments

Ceramic layer end face contact or collision .
2 When installing pipes, pipe centerline to be on the positive, the level to leveling , to ensure that both ends of the accurate surface at both ends to control the amount of dislocation within 1.0mm.
(3) When using a flexible tube connected to a flexible pipe nipple connection kit is installed at both ends of the pipe insertion length to adjust the symmetry , since the thermal expansion coefficient of composite steel pipe 1 /3, thus stretching the gap can be reduced to 3 - 5mm.
4 When flange connection , it must be flush with the flange face composite pipe ends .
5 Due to the excellent performance of the composite pipe welding , so welding pipe connection mode manner, when its groove weld using 70 ° -90 °, the blunt edge of 2-4mm without leaving gaps , should adopt a small current welding.

SHS (Self-propagating High-temperature Synthetic process) ceramic lined steel pipe and elbow create a new generation of abrasion and corrosion resistant engineering pipeline.

The Manufacturing Process of Pipe and Elbow: 
SHS (Self-propagating High-temperature Synthetic process) ceramic lined steel pipe and elbow create a new generation of abrasion and corrosion resistant engineering pipeline.The composite steel pipe is composed of three layers: ceramic, intermediate, and steel layers. The ceramic layer is formed by molten alumina at a temperature above 2500 degree. The molten alumina produced from the reaction Fe2O3+2Al=2Fe+Al2O3 spreads on the inside wall of the steel pipe under the influence of a centrifugal force, then solidifies, so the ceramic layer has high density and smooth surface and bonds to the steel pipe.
Abrasion Resistant Ceramic Lined Pipes have been uniformly produced by a thermite reaction induced under the influence of a centrifugal force (Centrifugal Thermite Process) without any high-temperature furnace facilities. The characteristic feature of the present process for forming uniform ceramic layers is in its reaction propagation as well as the reaction heat and centrifugal force. It is very important in improving the quality of the ceramic lined pipes to find the proper conditions of the reactant and centrifugal force; the former mainly determines the produced ceramic layer quality and the latter the achievement of layer separation and the mechanical properties of the pipes.

Ceramic lined tube has great resistance against corrosion, abrasion and thermal shock. Features and Advantages:
1). High Abrasion Resistant: Vickers hardness of the corundum lining is HV1100 to1500, as high as that of tungsten-cobalt hard alloys, and the abrasion resistance is 20 times as carbon steel pipes. The composite ceramic lined steel elbow was used in a mining plant for about fifty thousands hours. The general service life of common steel elbow is about 700 hours.
2). Corrosion Resistant: Corundum is a neutral material, and is acid-proof and fouling -free.
3). Heat Resistant: Ceramic lined composite steel pipe can work under circumstances of -50 to 800 Celsius degree .
4). Lower Weight and Convenient Installation: The ceramic lined steel pipes are lighter than alloy pipes, cast iron pipes, and cast stone pipes and can be welded or connected through flanges, which reduces the expense of transportation and makes the pipes easier to install. For the pipes with the same sizes, types and length, the weight of ceramic pipe is about 1/2 of the wearable cast alloy steel pipe's, while the cost has reduced 10%~20% per meter. The weight of ceramic lined steel pipe is about 1/3 of the cast stone bent pipe's, 1/2 of the cast stone straight pipe's.
5). Lower Cost: Ceramic lined pipes can take place of expensive stainless steel, titanium, nickel, cast stone or alloy pipes. Extended service life can also reduce maintenance cost.
