The finned tube is to improve the heat exchange efficiency. By adding fins on the surface of the heat exchange tube, the outer surface area (or inner surface area) of the heat exchange tube is increased, so as to achieve the purpose of improving the heat exchange efficiency. Such a heat exchange tube . Usually used for heat exchange between liquid and gas.
Finned tube is a heat exchange element. As a heat exchange element, finned tubes usually work under high-temperature flue gas conditions for a long time. For example, the finned tubes usually used in boiler or harsh environments, high temperature and high pressure, and in a corrosive atmosphere. This requires that the finned tubes should have high anti-corrosion properties, Anti-wear properties, lower contact resistance, higher Stability and anti-dusting ability.
There are many types of finned tubes, and new varieties are constantly emerging. According to the classification of processing technology, there are extruded fin tube; high frequency welded finned tubes; rolled formed finned tubes; suit formed finned tubes ; cast finned tubes; tension wound finned tubes; Inserted tubes.
According to the shape of the fins, there are square finned tubes; circular finned tubes; spiral finned tubes; longitudinal finned tubes; corrugated finned tubes; spiral serrated fins Helical Serrated Finned Tubes; pin-shaped finned tubes; integral plate-shaped finned tubes; inner finned tubes.
According to whether the fin material of the finned tube is the same as that of the base tube, it can be divided into: single metal finned tube, bimetallic composite finned tube.
Single metal finned tubes are classified by material into copper finned tubes; aluminum finned tubes; carbon steel finned tubes; stainless steel finned tubes; cast steel finned tubes.

1. The reliability of the hydraulic system mainly depends on the cleanliness of the hydraulic system, in addition to the performance of the hydraulic components. The main factor affecting the cleanliness is that the rust layer of the steel pipe cannot be removed. To this end the company is equipped with a shot blasting machine and uses the only special process in the country to handle: internal surface blasting - pickling - rinsing - passivation - sealing - electrophoresis, tubing also needs to pass before Internal surface cleaning - blow drying - oil rust prevention and other processes to ensure the stability of the entire hydraulic system.
2. All hydraulic components undergo hydraulic bench inspection before purchase into storage to fully ensure that the hydraulic components meet the calibration performance requirements.
1.Our company has 1000,600,500,100 and other series tonnage hydraulic presses, which can meet the bending forming of all arm plates, only the middle two welds, and all use carbon dioxide protection welding, the length of the weld is more than 500mm Automatic welding is used, which not only has a small weld seam, but also has a beautiful appearance, low stress, and high strength.
2, all components in the welding are used fixtures, fixtures to ensure the production accuracy.
3. All components are tested by ultrasonic weld after welding, which has high safety.
4, all the plates are used underwater plasma CNC cutting machine, CNC wire cutting machine, cutting machine cutting, so the production of high precision.
Third, paint:
1. The company is the sole manufacturer of wrecker manufacturers in the country, which is equipped with an electrophoresis production line. All metal structural parts are degreased, cleaned, rust-proofed, cleaned, surface-modulated, phosphatized, and electrophoretically treated before being assembled. More than 800 hours of sex, strong rust resistance.
2. Our company owns the original paint booth imported from Italy. After the electrophoresis primer, the surface is sprayed with imported ici paint and then baked by the paint booth. The appearance is beautiful, the strength is high, and the anti-rust ability is extremely strong; The customer asked for spraying, the appearance is more personalized.
Fourth, the vehicle:
1. The entire vehicle production process is strictly inspected according to the standard after blanking, bending, welding, assembly, rig testing, assembly, commissioning, and general inspection. The uploading rack test is a unique process of our company. Completely guarantee quality requirements, so that customers can rest assured that use.
2. Press the "wrecker standards" in the requirements, the number of new products in the approval test the reliability of the test was set at 500, and the standard, the number of tests required for the company's 2,000, much higher than the "wrecker "Car standards" requirements, so as to ensure the performance requirements of the vehicle.
Content introduction: First, the hydraulic system: 1, the reliability of the hydraulic system in addition to the performance of the hydraulic components itself, mainly depends on the cleanliness of the hydraulic system, and the main factor affecting cleanliness is the rust layer of steel pipe can not be removed. To this end, the company is equipped with a shot blasting machine and uses the only special process in the country.
