Simple chain type hydraulic jacking system is composed of one-stage double-acting hydraulic cylinder, pulley block, load-bearing chain and oil way etc. Moveable pulley is used to enlarge chain stroke, i.e. traveling distance of the cylinder is 1/2 of lifting distance of the chain. It applies to inverted installation and construction of various large storage tanks (steel) and various storage tanks.
LYT-type simple chain type hydraulic jacking system includes the following models: LYT-120-2700, LYT-200-2700, and LYT-300-2700 etc. (those with special stroke need to be customized).

LYT-type simple chain type hydraulic jacking system is used to firstly lift the tank roof and the top (first layer) siding of the tank. It's required to group weld tank siding when the lifting height of siding exceeds the second siding (the second layer from the top) by 30-50mm, and group weld the third layer (the third layer from the top to the bottom) of the tank after lifting again, lift successively, group weld the siding of the tank layer by layer, until the last layer of siding.
LYT-type simple chain type hydraulic jacking system is used for lifting. When oil enters the hydraulic jack, the movable pulley is pushed upward by pressing the piston, thus driving the load-bearing chain to lift the expansion ring. In this way, the whole tank (including tank roof) is lifted up, until it reaches the pre-set height (there is a voidance of the next layer of plate). The siding in this layer is surrounded for butt welding. After the positioning block is welded, hydraulic hoist returns and the lift tank falls back to the newly-surrounded siding. After welding of circular seam and vertical seam, the door-type card for fixing expansion ring is cut off and the expansion ring is released. In this way, the hoist returns and expansion ring falls to the Model of hydraulic pump station Tank volume Rated pressure Rated flow Power Control voltage of solenoid valve Motor drive rate YB-7.2 220L (700*550*580) 25Mpa 7.2L/min Three-phase Four-wire (380V) 220V 5.5KW YB-14.5 340L (750*650*650) 25Mpa 14.5L/min 220V 7.5KW Mode of LYT-type hoist Rated lifting capacity (KN) Hydraulic area (mm) Rated oil pressure (MPa) Piston stroke (mm) Chain stroke (mm) Cylinder safety equipment Reinforcement measures LYT-120-2700 120 11304 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods LYT-200-2700 200 18859.6 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods LYT-300-2700 300 25434 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods bottom of tank siding. Then, the next circular plate is expanded and transfer rib plate, such as door-type card, is welded for lifting, and so forth. The group welded tank is lift, until group weld of the last layer of siding, so that the whole storage tank is installed with this inverted method.

(3) Gun delivery method: zigzag swing.
(4) Flat fillet welding does not swing or swing slightly.
(5) The vertical angle is welded upward, and the triangular gun is used.
(6) Welding torch transition: stay on both sides of the molten pool and transition at the front 1/3 of the molten pool.
(7) Gun angle: perpendicular to the weld bead, at an angle of 80-90° along the direction of the gun.
(8) Test plate: the gap is 2.0-2.5mm, and the arc starting point is slightly smaller than the arc ending point. No blunt edge, anti-deformation 1°.
(9) To prevent defects: prevent the angle from melting - burn through the angle. No fusion between layers - pay attention to the gun angle.
The direction of the arc axis of the tank welding machine is perpendicular to the direction of the penetration depth of the weld. During welding, a water-cooled copper slider is used on the front of the weld, and a water-cooled gear row (or pad) is used on the back of the weld. The flux-cored wire is fed into the weldment and in the groove formed by the stopper, the four sides of the molten pool are constrained to realize single-sided welding and double-sided forming at one time. Tank welding machine is a high-efficiency welding technology and equipment.
In recent years, the promotion and application of tank welding machine in engineering has achieved good results, and in-depth research on the fusion welding mechanism of gas-electric vertical welding technology. Tank welding machine has good welding quality, high deposition speed and low comprehensive cost, which provides a broad prospect for the popularization and application of this efficient automatic welding technology and equipment.

Because the pipe spool fabrication line is very smart, pipe spools are used in almost all industrial applications. The specific part of the pipe spool fabrication line can be arranged in various sizes and shapes of the target application area. Therefore, the most common application areas of tubing can be divided into: household applications, industrial applications (factories), medical applications and construction applications.
Here is the content list:
l What are the application characteristics of pipe spool fabrication line?
l What are the areas of use of pipe spool fabrication line?
l What does the pipe spool fabrication line meet the needs of the application?
The pipe spool fabrication line is a component that can be welded or assembled to each other to form the entire pipeline system. Before discussing the application of pipe spool fabrication line, it is best to start with the understanding that the pipe is a straight longitudinal pipe used to transport fluid.
However, spools are pipes with complex shapes composed of different sections. They are used for prefabricated parts produced by pipe spool fabrication line, including shot blasting machines, pipe cutting machines, beveling machines, pipe fitting machines, pipe welding machines and other equipment.
Use of pipe spool fabrication line
① Residential use: cold, hot water and heating for houses and villas.
② Public buildings: water supply and floor radiant heating for public buildings such as office buildings, markets, theaters, and military camps.
③ Transportation facilities: piping for airports, passenger stations, parking lots, garages, and highways.
④ For animals and plants: piping for zoos, botanical gardens, greenhouses, and chicken farms.
⑤ Sports facilities: cold and hot water pipes for swimming pools and saunas.
⑥ Sanitary use: piping for water supply pipes and hot water pipes.
⑦ Other: industrial water pipes.
Features of pipe spool fabrication line
⑧ Good flexibility
⑨ Corrosion resistance, water scale
⑩ High temperature and high pressure resistance
⑪ long life
⑫ Easy and fast construction
The pipe spool fabrication line is a component that can be welded or assembled to each other to form the entire pipeline system. In modern engineering applications, the pipe spool fabrication line is used to transport required materials almost anywhere.
Domestic applications: Most domestic applications use steel pipe systems because of their mechanical durability and high corrosion resistance. The material of the short tube is domestic (domestic) stainless steel. The entire piping system of the house consists of stainless steel pipes and spools.
Industrial applications: Energy and certain raw materials are transported through the use of complex spool systems. Factories usually produce by-products such as exhaust gas and liquids. These exhaust gases and liquids must be removed from the production area. Therefore, these substances can also be removed through the pipeline system. In industries where space constraints can cause difficulties, some complex spool systems are the first choice. In addition, extremely long pipeline systems are also used for energy (oil, natural gas, etc.) transportation. These extra-long pipe systems have spool sections of various sizes and shapes.
Medical applications: Simple pipe spool fabrication line are even used in surgical and dental applications. The biocompatibility of the tubing used is the most important criterion in medical applications. Therefore, compatible pipe spool fabrication lines are used for bone healing or medical processing applications.
Construction applications: Pipes are one of the most common areas of use. For high strength, the required pipe material is usually selected as steel. When the foundation of the building is too weak to support the building, steel pipes are used as the support element of the building. In some architectural works, only complex spool systems are used for construction. The pipe spool fabrication line is also used to build ships and refineries.
Pipe spool fabrication line components can be divided into large and small straight pipes and accessories. In addition, accessories can also be divided into flanges, tees and elbows. These different components are widely used for other needs.
The pipe spool fabrication line must meet some essential requirements to generate effective fluid flow. Therefore, the complex pipe spool fabrication line must have high flexibility, cycle life, pressure rating, chemical resistance and corrosion resistance.
For example, pipe spool fabrication lines are commonly used in oil refineries and crude oil transportation lines. The sharp bend of the pipeline will change the type of oil flow from laminar to turbulent. Therefore, the turbulence of oil may cause corrosion and corrosion of the system.
These corrosion problems can be identified from the horseshoe-shaped cracks. Since these crevices remove material from the surface, they can cause leakage in the pipe spool fabrication line and are harmful to oil pipelines. Therefore, for the required pipe spool fabrication line application, the correct selection of materials and components is essential to the safety of the system!If you want to know more about high-quality tank welding machine products, you can also contact us at any time.
