Harbin Sandblasting pipe The quality is closely related to the material selection and the manufacturing process. 1. The galvanized air ducts of different specifications are made of plates of different thicknesses according to the specification requirements. On the basis of being familiar with the size and layout of air duct in the drawing, skilled technicians shall set out and cut materials to ensure that the production and installation of air duct meet relevant standards. 2. The galvanized sheet air duct flange will be made uniformly according to the series of specifications specified in the drawing. In addition, the bolt holes of the flange will be punched at a fixed distance with a punch and a mold. The forming welding of the flange will also be positioned with a special mold to ensure that the air duct flange of the same specification has interchangeability. Compared with the traditional galvanized iron pipe made by hand, the round galvanized air pipe made by mechanism has the following advantages: (1) The round galvanized air pipe has good sealing performance. (2) Both strength and rigidity are good. (3) The ventilation resistance is small, the ventilation noise is small, and the round pipe is better than the square pipe. (4) The galvanized air duct is easy to install and has few connection points. (5) Circular wear-resisting Sandblasting pipe High grade, beautiful appearance. Galvanized spiral duct is very suitable. Generally, galvanized air ducts are used, while stainless steel pipes are very suitable for galvanized spiral air ducts in corrosive and particularly humid places. Generally, galvanized air ducts are used, while stainless steel pipes are used in corrosive and particularly humid places.
wear-resisting Sandblasting pipe The inner and outer walls are smooth, the resistance of the air duct is small, no secondary noise is generated during air supply and exhaust, energy consumption is reduced, and operation costs are saved. The product can be fabricated on site, cut, drilled, drilled, and installed simply, saving labor and time, reducing the user's investment cost, shortening the construction period, high performance price ratio, and cheaper than other materials. After installation, there is no need for maintenance, reducing maintenance costs. The key points of whether galvanized sheet air duct material galvanized sheet is corroded are mainly reflected in the following three aspects: ① The first corrosion of galvanized sheet in the entire service life cycle is the oxidation of the galvanized layer on the surface, resulting in white rust. After a little longer time, the white rust on the surface further reacts with carbon dioxide and other impurities in the humid air to form black spots. When the galvanized sheet is used for a long time and the galvanized layer is severely corroded, the steel base loses the sacrificial anti-corrosion effect of zinc, and begins to oxidize to generate red rust. Once the steel base begins to oxidize, the corrosion rate becomes very fast, and the life of galvanized sheet ends. ② In addition, there are two special corrosion conditions of galvanized sheet, namely, black stain. One is that after being used for a period of time, due to the influence of lead and other elements in the zinc coating, the galvanized sheet will become black in the matte part of the zinc flake. The blackened zinc coating still has a protective effect on the steel base, but has a certain impact on the service life. ③ Sandblasting pipe Price It has excellent corrosion resistance in dry or pollution-free environment. However, in the polluted environment, the service life will be greatly shortened, so it is necessary to pre coat the film into color plates before use.

You know? Harbin Sandblasting pipe Are there reinforcement regulations and requirements? Stainless steel welded air duct is a commonly used equipment, and its reinforcement actually has regulations and requirements, do you know? If in pipe support is adopted, the spacing between each support point and the edge or flange of the air duct shall be uniform, and the value shall not be greater than 950 mm. If the corrugated bars or wires are used for reinforcement, the arrangement should be regular and the spacing should be even. Moreover, there should be no obvious deformation and other problems for the board surface. If the welded air duct is reinforced, it should be made of ribbed bars, vertical bars, angle steel, flat steel, reinforcing bars and supports inside the duct. The appropriate one can be selected according to the actual situation and needs. If angle steel or reinforcing bars are used, they should also be arranged neatly and symmetrically. The height shall not be greater than the flange width. Principles and requirements for stainless steel air duct plate connection. When the thickness is less than or equal to 1mm, the splicing of plates shall be done by biting or riveting. When the thickness of plates is greater than 1mm, argon arc welding or electric arc welding shall be used instead of gas welding. The mature argon arc welding process of "single side welding, double side forming" shall be adopted; When assembling weldments, the welding materials and process measures selected for spot welding shall be consistent with the formal Sandblasting pipe Price The requirements are the same. The misalignment deviation of the pipe butt joint is less than 20% of the wall thickness and less than 2mm. Adjust the butt joint clearance, and do not use the method of heating, tensioning and twisting the pipe. It is not allowed to strike an arc or test the current on the weldment, and the pipe surface shall be free of arc scratch and other defects. Splash prevention measures shall be taken during welding. After welding, the slag and spatter shall be cleaned with stainless steel flat shovel. After welding, the slag on the weld surface and the spatter on both sides shall be cleaned.
Sandblasting pipe Price It has become the standard configuration of the modern new ball mill, but many problems may occur during the use or installation of the rubber lining plate, which will cause the failure of the rubber lining plate of the ball mill. Here is a brief introduction to the causes of the more common failure of the rubber lining plate of the ball mill. The design and installation are not professional and reasonable. The design and installation are also common problems for many novice manufacturers. For example, the bolt holes for fixing the ball mill lining plate are square, which will cause stress concentration and fracture. Adjust the size of lining plate to control the gap between lining plates at about 8mm; The installation quality of lining plate is very important to the safe operation of ball mill. First, tighten the fixed wedge symmetrically, put the lining plate in sequence, and then use the tightening wedge to secure it; Therefore, professional installation guidance can easily avoid these problems. The reason why the rubber lining plate of the ball mill does not match the steel ball is relatively common, and it is easy for many novice manufacturers to ignore and make mistakes. During the operation of the ball mill, the rubber lining plate of the ball mill, materials and steel balls promote the normal grinding and crushing of the ball mill due to the interaction of forces. The hardness of materials is related to wear resistance, and the wear resistance increases with the increase of hardness, Harbin Sandblasting pipe It is a pair of friction pairs, and the increase of hardness of one side will cause the wear of the other side to increase. Therefore, the high wear-resistant rubber lining plate is matched with the high wear-resistant steel ball, and the low wear-resistant rubber lining plate is matched with the low wear-resistant steel ball, so as to ensure the normal wear of the rubber lining plate of the ball mill and extend the service life of the ball mill.
