After years of development, China's double-cylinder dryer equipment industry has begun to enter a more mature stage, which can better meet the actual needs of users in various fields. In view of the "green" advantages of double-cylinder dryer equipment, the application is increasingly widespread. In terms of food and drug drying, the demand for larger-sized vacuum double-cylinder dryer equipment will gradually increase, and the market prospect is very huge.
In 2013, the overall economic operation of the petrochemical industry was not optimistic, which was a big challenge for the dryer equipment industry. The real big shocks are small enterprises. Large enterprises have not been affected too much. Some large enterprises have only reduced their profit margins, and the output value has not decreased.
At present, the domestic double-tuber dryer equipment market is mainly dominated by medium and low-tech products. With the continuous fierce competition, domestic dryer equipment enterprises must improve product quality through technological advancement, absorption of foreign advanced technology and independent innovation. To meet market production needs. Industry analysis, there are five major development trends in China's dual-tuber dryer equipment in the future.
First, the combination of several heat transfer forms makes it take advantage of various heat transfer forms in different periods of drying, making the equipment more reasonable.
Second, the equipment will gradually achieve large-scale development. No matter which industry has the best economic scale, the amplification technology of the double-cylinder dryer equipment can ensure large-scale production, so the large-scale research of equipment is one of the future development directions.
Third, the dryer equipment will become specialized.
Fourth, the development of multi-stage and combined drying systems will be applied. Different types of drying equipment can be applied to different materials or different drying stages of materials. Combined drying can optimize the drying process to the maximum and make the drying system more reasonable.
Fifth, the dual-cylinder dryer equipment will gradually become more multifunctional. Nowadays, the drying equipment is not only limited to the drying operation, but sometimes the pulverization, classification, and even heating reaction are collected in one machine, which greatly shortens the production process and diversifies the functions of the equipment. Zhengzhou Hengxing Heavy Equipment Co., Ltd. is engaged in large and medium-sized series of mining machinery. The main products are: dryer, slime dryer, double cylinder dryer, three cylinder dryer, rotary dryer and other heavy machinery equipment. The main manufacturer. Stellar dryers are low in price and have many varieties. Welcome to buy.

Butt welded pipe fittings are the most widely used pipe fittings. It is made of high-quality steel pipe and is formed by heating or pressing. Carbon steel pipe fittings are divided into carbon steel elbow, carbon steel tee, carbon steel cross, carbon steel reducer (large and small head), carbon steel head (cap) 5 series. The main implementation standards include GB, DIN, ASME, JIS, GOST. The biggest use of carbon steel pipe fittings is to connect pipes, Valves, pumps and other equipment to form a complete piping system.
When using, the pipe fittings are evenly welded with the flange or directly with the pipeline, so that the entire pipeline is integrated and starts to work normally.
Pipe fittings are widely used in water, beverage, beer, food, petrochemical, nuclear power, machinery, medical equipment, fertilizer, shipbuilding, waterproofing and other pipeline systems. It is the most widely used pipe fittings in the piping system and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding, air conditioning and other departments. The tube cap is also the end cap on the pressure vessel, which is a main pressure-bearing component of the pressure vessel. The quality of the cap is directly related to the long-term safe and reliable operation of the pressure vessel.
Types of butt welded fittings:
According to the model can be divided into: ANSI B16.9 ANSI B16.28 JIS B2311SGP DIN 2605, DIN2615 DIN2616 DIN2617
According to the shape, it can be divided into: elbow, tee, cross,
Reducer (large and small head), head (cap)
According to the thickness can be divided into: SCH 10 SCH20 SCH30 STD SCH40 XS SCH80 XXS
According to the process, it can be divided into: stamping, pushing
According to the material can be divided into: carbon steel, stainless steel, alloy steel
1: Put the high-quality steel pipe, the raw materials according to the required size, and put it into the ring-shaped intermediate frequency furnace to heat and push to form or place it on the mold and extrude it by the press.
2: Pass the shaped elbow blank through the special CNC lathe for pipe fittings according to the drawing. Welding groove processing is performed on the two ends of the elbow blank, with a certain angle and a certain edge, and the angle and deviation range are strictly in accordance with the requirements of the drawings.
3: Put the elbow blank after shaping and beveling, and put it into the shot blasting machine for shot blasting on the surface of the pipe to remove the oxide skin on the inner and outer surfaces.
4: The finished pipe fittings are inspected according to the requirements of the drawings for the thickness and radius of curvature and straightness.
5: The pipe fittings that have passed the inspection will be typed on the end face according to the customer's requirements, and the pipe caps will be treated with anti-rust treatment according to the customer's requirements, and then put into wooden boxes or wooden pallets for transportation.
Standard for butt welded pipe fittings: ANSI B16.9 ANSI B16.28 JIS B2311 SGP DIN 2605, DIN2615 DIN2616 DIN2617
Thickness of pipe fittings: SCH 10 SCH20 SCH30 STD SCH40 XS SCH80 XXS
Size of butt welded fittings: 1/2"-48" (DN15-DN1200)
