The problem of collection of ash, worn down, low temperature corrosion exists in the air preheater to effect the safe and economical operation for the boiler unit. At the moment, the investment of air preheater is 6%-8% of the whole boiler investment in the industrial boiler and power station boil, due to the problem of collection of ash, worn down, low temperature corrosion to incur the direct loss of replacing equipment and shutting down is 4-5% of the operation cost and the loss will be more large when the boiler is shut down incurred by this problem.
The enamel steel tube is manufactured with the enamel which is developed by our company with the scientific formula and is evenly coated on the surface of the steel tube by the auto enamel tube production line. To use enamel tube as the heat exchange parts will be anti-abrasion and anti-corrosion, the surface is smooth and low cost of maintenance.
Hollow Section steel Tube is the general name for the steel pipe other than thecircular steel pipe. Such as square, rectangle, oval,elliptical, cone, trapezoidal, spiral, etc. Different steel pipe can more adapt to the particularity of use conditions, save metal and improve the labor productivity of parts manufacturing. It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, light textile and boiler manufacturing. The methods of producing different pipes are cold pulling, electric welding, extrusion and hot rolling, etc. Compared with the round tube, the different tubes generally have a larger moment of inertia and cross section modulus, and have a large bending resistance and torsion resistance, which can greatly reduce the structural weight and save steel.
Stainless steel tube is a hollow long strip steel made of stainless-steel material. Because of its excellent corrosion resistance, it is mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transportation pipelines and mechanical structural components. In addition, when the bending and torsion strength are the same, the weight is light, so it is also widely used in manufacturing mechanical parts and engineering structures, but also commonly used in the field of furniture decoration.
Stainless steel pipe is divided into seamless pipe and welding pipe according to the production mode, seamless steel pipe can be divided into hot rolling pipe, cold rolling pipe, cold pulling pipe and extrusion pipe, etc., cold pulling and cold rolling is the secondary processing of steel pipe; welding pipe is divided into straight welding pipe and spiral welding pipe.
Stainless steel pipes can be divided into round tubes and different tubes according to the cross-sectional shape. The form tubes have rectangular tubes, rhomboid tubes, ellipse tubes, hexagonal tubes, octagonal tubes and various cross-sectional asymmetric tubes.
It can be divided into Austenitic Stainless Steel Tube Ferritic Stainless Steel Tube Martensitic Stainless Steel Tube and Duplex Stainless Steel Tube by the type of stainless steel.

Cast Iron and Ductile Iron tube and fittings PL739
Cast Iron and Ductile Iron tube and fittings can be offered by our comapny to meet different engineering needs.
The difference between ductile iron and gray iron
1. Different chemical composition
Nodular cast iron contains nodular graphite, which can improve its toughness and strength, while reducing brittleness. Gray cast iron contains a lot of carbon, so that its hardness and wear resistance is high, but the toughness is poor.
2. Different organizational structures
The structure of nodular cast iron contains nodular and ferrite, and the distribution of nodular is uniform. While the structure of gray cast iron is mainly ferrite and pearlite, and the distribution of pearlite is uneven.
3. Different performance
Ductile iron has high strength and toughness, and has good corrosion resistance. It is uitable for the manufacture of high load and high pressure parts. The hardness and wear resistance of gray cast iron are high. It is suitable for the manufacture of friction and wear parts.
Application field
Cast iron : because of its low strength and good vibration resistance. It is often used in the production of parts under compressive stress, such as box, base, etc.
Ductile iron : because of its high strength and good toughness. It is often used in the manufacture of parts requiring high strength and toughness, such as crankshaft, connecting rod and so on.
1, With very good adhesion, can dissolve much iron oxide in metal surface, makes very strong combination with metal body.
2, Can be combined with cover coat in high level.
3, With very good elasticity and compressive strength. Prevent and decrease damage due to mechanical stress.
4, With less viscosity and surface tension, its good for escape of gas when firing. Reduce bubbles on cover coat. To ensure the smooth surface of enamel products.
5, With suitable expansion coefficient similar as steel plate.
