Hydraulic pipelines, simn are provided individually as a result of the five significant components (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur S).1. Smooth steel pipe for fluid: GB8163-992. Seamless steel pipe for central heating boiler: GB3087-19993. High pressure smooth pipeline for boiler: GB5310-95 (ST45.8- type).4. High-pressure seamless steel pipes for plant food devices: GB6479-1999.5. Smooth steel pipeline for geological exploration: YB235-70.6. Smooth steel pipe for oil exploration: YB528-65.7. Smooth steel pipe for oil fracturing: GB9948-88.8. Unique seamless pipe for oil drill collar: YB691-70.9. Smooth steel pipeline for auto half shaft: GB3088-1999.10. Seamless steel pipeline for ships: GB5312-1999.11. Cold-drawn cold-rolled precision seamless steel pipeline: GB3639-1999.Different alloy pipes 16Mn, 27SiMn?, 15CrMo?, 35CrMo?, 12CrMov?, 20G, 40Cr, 12Cr1MoV, 15CrMo? steel pipelines are divided right into seamless steel pipes and also welded steel pipes according to different production processes. Seamless steel pipelines are seamless steel pipes made from steel ingots, pipe billets or steel poles perforated.Hydraulic pipeline weight formula: [( outer diameter-wall thickness) * wall surface thickness) * 0.02466= kg/m (weight per meter).Advantages of hydraulic.Compared to mechanical transmission as well as electric transmission, hydraulic transmission has the complying with benefits:.1. http://bvkrongbong.com/Default.aspx?tabid=120&ch=471065 of hydraulic transmission can be comfortably and also flexibly prepared according to requirements.2. Light weight, tiny dimension, small activity inertia as well as rapid reaction rate.3. Hassle-free procedure as well as control, which can recognize stepless rate guideline in a variety (speed guideline variety as much as 2000:1).4. The overload protection can be realized immediately.5. Generally, mineral oil is used as the working tool, the loved one moving surface can be lubed on its own, as well as the solution life is long;.6. It is easy to understand linear activity/.7. It is very easy to recognize the automation of the device. When the electro-hydraulic consolidated control is taken on, not only a higher level of automatic control process can be understood, but also remote control can be realized.Downsides of hydraulics.1. Due to the large fluid circulation resistance and also leak, the performance is reduced. Otherwise dealt with correctly, the leak will certainly not just infect the site, however may additionally cause fire as well as explosion crashes.2. As the working efficiency is conveniently impacted by temperature level changes, it is not ideal to work under very low or really high temperature level problems.3. The production accuracy of hydraulic elements is high, so the cost is more pricey.4. Because of the leak and also compressibility of the liquid medium, a stringent transmission proportion can not be obtained.5. When the hydraulic transmission stops working; the use and upkeep need a higher technical level, it is not simple to find out the cause.Adapter installment.The hose pipe needs to not be excessively curved when it is moving or at rest, nor can it be curved at the origin, yet must start to bend at least 1.5 times its diameter;.When the hose is transferred to an extreme position, it needs to not be pulled too tightly, it should be loose;.Attempt to avoid torsional contortion of the hose;.<img width="313" src="">Maintain the hose pipe as much away as possible from the warm emitting elements, and it is necessary to mount a warm shield;.Prevent exterior damage to the hose pipe, such as long-lasting friction externally of the same part during usage;.There ought to be assistance parts if the hose pipe's very own weight triggers too much deformation.Pipeline setup.Prior to installation, all steel pipelines can be marinaded first, especially the steel pipelines linked to the ferrule kind pipe joints should be marinaded initially, and also then the ferrule is attached to the pipeline end in advance;.All pipe joints must be cleaned with kerosene prior to installation, the O-rings inside must be briefly gotten rid of for storage space, and after that place on after the formal installment;.During building, keep the oil ports, pipeline joints, pipeline ends and also other openings of pumps, distributors as well as various other tools tidy, and do not allow international items such as water and also dust to enter;.The pipeline shall be stocked a free state, and also the welded pipeline will not be forcibly dealt with as well as connected by using excessive radial pressure;.The oil hole of the bearing seat must be signed in development to see if the inner oil circuit is unblocked and also if the oil port thread matches the joint.Pipeline cleansing.In order to make sure the cleanliness of the lubrication system and also provide the bearings of mechanical equipment with tidy grease, the pre-installed pipes should be gotten rid of and also cleansed. There are 2 kinds of cleaning: kerosene cleaning as well as pickling.( 1) Items and approaches of kerosene cleansing.Item. Copper pipes, stainless steel pipes;.The steel pipelines that have actually been pickled before pre-installation, and also the inner wall is totally free of rust and iron scale; 2. The pipe joints that were dirtied during the pre-installation; 3. Get rid of the pipes as well as joints that require to be cleaned, and use towel (( It is necessary not to lose woollen).( 2) Marinading things and methods.Object. Steel pipes that have actually not been marinaded prior to pre-installation; steel pipelines that have actually been marinaded but are now seriously corroded.Use tidy water to eliminate the dust on the pipeline; 3. Wash with clean water For the accessories produced in the above procedures, the inside of the pipe need to be washed with high-pressure water; 5. In order to efficiently dry out the pipeline, the pipeline must be immersed in warm water or heavy steam dried out.The steel pipelines that have actually been pickled before pre-installation, as well as the inner wall is totally free of corrosion and iron range; 2. Remove the pipelines as well as joints that need to be cleansed, as well as utilize cloth (( It is necessary not to drop wool). Use clean water to eliminate the dust on the pipeline; 3. Wash with clean water For the accessories produced in the above procedures, the inside of the pipeline ought to be washed with high-pressure water; 5. In order to successfully dry the pipeline, the pipe should be immersed in hot water or heavy steam dried.
