New-style and compressed circle belt pressure vessel

Current pressure vessel makes 5 　 workload is the biggest is to solder (occupy 50% ～ 60%) , especially of link welding line soldering is very difficult. So, want to eliminate large loop welding line to be able to improve the technical economic norms of pressure vessel only, improve productivity, and new-style and compressed circled belt pressure vessel to solving this problem effectively, introduce as follows now: Raw material of 1) cylindrical shell: New-style and compressed the cylindrical shell that circles belt pressure vessel by inside the composition of flat metal strip that canister and crisscross of the wall outside its twine, the tube inside its is thinner, usable and general board coils solder is made. A large number of raw material are rolling type simple, low-cost, material is qualitative the flat metal strip with reliable, extremely wide origin. It has good mechanical performance, can become roll supply, utilization rate is extremely high (its integral performance and cost all under any thick board with thin plate) . 2) machining: Only inside the wall outside the canister needs to repair grind, of container cylinder part multilayer the structure reduced the treatment amount in rough machining process greatly, metallic utilization rate is high, go easily simply. 3) solder: Only inside canister and circle the two end of the belt to need to solder, decreased greatly to solder quantity. 4) quality inspection: Solder of mural Bao Yi, quality gets more easily assuring, easy examine, only inside the canister needs nondestructive flaw detection, container quality is reliable. 5) heat treatment: Only inside the canister requires heat treatment, do not require installation of large heat treatment. 6) makes equipment: Large simple and easy circle taking a machine tool is not new-style and compressed a exclusive special device in circling belt pressure vessel to make a process, be a kind need not lathe bed and bearing container implementation rotates with send those who lead campaign is simple twine device, can go all out to install and be become by the profiled bar such as channel or I-steel. Can design detachable structure, the operation is apt, circle belt efficiency is tall, for large the spot that circles belt pressure vessel is circled make offerred advantageous condition. New-style compressed in circling belt container to make a process, need only will inside canister hoisting takes a machine tool at circling, compressed circle belt in thin inside mechanization is automatic and successive outside the canister twine, till achieve place to need ply requirement, just need vessel discharge. Circle accident of the internal diameter bulk that makes container, cylindrical shell, implement mural ply and weight all can be inside very big range change. It can assure metal strip not only twine quality, and still can make metal strip is twined have taller efficiency. 7) makes cost: Production charge can reduce 30% ～ 50% , greatly under container of force of other much lamination, have remarkable economic benefits. 8) workmanship technology: Circle take a machine tool simple easy operation, according to container the level of the stress that bypass a layer below working status can be calculated those who give every metal band is initiative twine data, use very simple circle take a machine tool to be able to be achieved worry a demand, of flat metal strip twine do not have between the layer " buckle close " precision requirement, do not need to control interference of face of the joint between the layer strictly. 9) manufactures efficiency: Circle make a large container need ～ 100 hours 200 hours only, working procedure is little, periodic short, can improve work efficiency one times. 10) uses sex of on the safe side: Cylindrical shell is seamed without large loop, the metal strip layer that crisscross twines has " breathe freely " action, circle take a layer to be able to bear already high-pressured force, make to using high strenth steel again inside protective effect has when canister happening is destroyed. Although inside canister existence blemish, because circle belt the layer uses prestressing force to twine and container is unapt happen fragile break although the canister inside its falls to produce burst by a variety of reasons in actuating pressure,destroy; , also " leak only curb explodes " , use on the safe side, need not set explosion proof case additionally again. Ply of 11) cylindrical shell: Canister ply occupies the 1/4 ～ 1/6 of total ply only inside. Stress of the canister inside 12) distributings: Multilayer combination, because metal strip is used,pull stress to twine beforehand, container axial stress is little, can make " the canister inside low stress " structure, make container is below working status, diameter, annulus distributings to stress even. 13) produces government: Very simple. 14) other: New-style and compressed circle weight of belt pressure vessel light, specific power consumption can be saved in production process 80% . Introduce through above knowable, new-style and compressed circle belt pressure vessel to be able to assure the most advantageous workmanship condition already, can increase strength again, and have " leak only curb explodes " safe character; And because metal strip is executed,change prestressing force is twined, reach to normal temperature, low temperature, high temperature strong corrode wait for a circumstance to all can suit. Accordingly it is a kind of structure admirable, production cost is low, than already the container of some similar forms has dependability of more expensive safety in operation, comfortable stress container of extremely strong much lamination force structure. It is sure more apply to the domain such as station of oil, chemical industry, metallurgy, light industrial, serious chance, food, gas, nucleus, aviation widely, and have wide development perspective.
