standard intro<br>
Hydraulic pipes, simn are provided independently due to the 5 major elements (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur S).

1. Smooth steel pipe for fluid: GB8163-99

2. Smooth steel pipe for central heating boiler: GB3087-1999

3. High stress seamless pipeline for boiler: GB5310-95 (ST45.8- type).

4. High-pressure seamless steel pipelines for fertilizer devices: GB6479-1999.

5. Seamless steel pipeline for geological exploration: YB235-70.

6. Smooth steel pipe for oil drilling: YB528-65.


7. Smooth steel pipe for petroleum breaking: GB9948-88.

8. Unique seamless pipeline for oil drill collar: YB691-70.

9. Smooth steel pipeline for vehicle fifty percent shaft: GB3088-1999.

10. Seamless steel pipe for ships: GB5312-1999.

11. Cold-drawn cold-rolled precision seamless steel pipeline: GB3639-1999.

Numerous alloy pipelines 16Mn, 27SiMn, 15CrMo, 35CrMo, 12CrMov, 20G, 40Cr, 12Cr1MoV, 15CrMo steel pipelines are divided into seamless steel pipelines and also bonded steel pipes according to different production procedures. Smooth steel pipes are seamless steel pipes made from steel ingots, pipeline billets or steel rods perforated.

Hydraulic pipeline weight formula: [( external diameter-wall density) * wall density) * 0.02466= kg/m (weight per meter).

Benefits of hydraulic.

Contrasted with mechanical transmission and electrical transmission, hydraulic transmission has the complying with benefits:.

1. Various components of hydraulic transmission can be conveniently and flexibly organized according to requirements.

2. Lightweight, little size, tiny motion inertia as well as rapid reaction speed.

3. Hassle-free procedure and also control, which can understand stepless rate regulation in a vast array (rate law range up to 2000:1).

4. The overload protection can be realized immediately.

5. Normally, mineral oil is used as the functioning tool, the family member moving surface area can be lubed by itself, as well as the service life is long;.

6. It is easy to realize linear activity/.

7. It is easy to realize the automation of the machine. When the electro-hydraulic consolidated control is taken on, not only a greater degree of automated control process can be understood, however also push-button control can be understood.

Disadvantages of hydraulics.

1. As a result of the large liquid circulation resistance and leak, the performance is reduced. If not dealt with properly, the leak will certainly not only pollute the website, yet may additionally cause fire and also surge mishaps.

2. As the functioning performance is conveniently influenced by temperature adjustments, it is not ideal to function under really reduced or extremely high temperature problems.

3. The manufacturing accuracy of hydraulic parts is high, so the rate is extra costly.

4. Because of the leak and compressibility of the fluid medium, a rigorous transmission ratio can not be obtained.

5. It is hard to discover the reason when the hydraulic transmission falls short; the usage and also upkeep need a greater technological level.

Adapter setup.

The hose pipe ought to not be exceedingly bent when it is moving or at rest, nor can it be bent at the root, but must begin to flex at the very least 1.5 times its diameter;.

When the tube is relocated to an extreme setting, it must not be drawn also firmly, it must hang;.

Try to avoid torsional deformation of the tube;.

Keep the tube as far as possible from the warm emitting components, as well as it is necessary to mount a warmth shield;.

Prevent outside damage to the hose pipe, such as lasting rubbing on the surface area of the same component throughout use;.

If the tube's very own weight triggers excessive deformation, there ought to be support parts.

Pipeline installation.

Before setup, all steel pipelines can be marinaded initially, especially the steel pipes attached to the ferrule type pipe joints ought to be marinaded initially, and afterwards the ferrule is attached to the pipe end ahead of time;.

All pipeline joints need to be cleaned with kerosene prior to installation, the O-rings inside must be temporarily eliminated for storage space, and after that place on after the official setup;.

During building and construction, keep the oil ports, pipeline joints, pipeline ends and other openings of pumps, distributors and also other devices clean, and also do not allow international items such as water and also dirt to get in;.

The pipe shall be stocked a complimentary state, as well as the bonded pipe shall not be by force fixed as well as connected by using excessive radial force;.

The oil opening of the bearing seat should be signed in advancement to see if the interior oil circuit is unblocked and also if the oil port string matches the joint.

Pipe cleansing.

In order to guarantee the cleanliness of the lubrication system as well as provide the bearings of mechanical equipment with clean oil, the pre-installed pipelines must be gotten rid of and cleaned. There are two sorts of cleansing: kerosene cleaning as well as pickling.

( 1) Items and also techniques of kerosene cleansing.

Item. Copper pipelines, stainless steel pipes;.

method. 1. The steel pipes that have been pickled prior to pre-installation, and also the inner wall surface is without rust as well as iron scale; 2. The pipeline joints that were stained during the pre-installation; 3. Eliminate the pipes and also joints that need to be cleaned, and utilize towel (( It is needed not to drop woollen). Clean the inside of the tube with kerosene, saturate both ends and also joints in kerosene to clean, then layer the within of television with engine oil or loaded with oil, as well as seal both ends for installation; 4. After cleaning, there must be no visible contaminants. ( bsp male 60 degree seat/o-ring seal variable diameter hydraulic hose adapter fittings as iron filings, fibrous contaminations, welding slag, etc), pay special attention to the welding slag on the inner wall of the weld must be completely cleansed.

( 2) Marinading methods and also things.

Item. Steel pipelines that have not been marinaded before pre-installation; steel pipelines that have been pickled yet are now significantly worn away.

technique. 1. Utilize a degreasing representative to eliminate the grease sticking to the pipeline; 2. Use tidy water to remove the dust on the pipeline; 3. Eliminate the corrosion areas on the pipe wall surface, rolled iron filings, etc in the pickling service; 4. Wash with clean water For the accessories created in the above operations, the inside of the pipeline must be cleaned with high-pressure water; 5. Reduce the effects of the acid service staying on the pipe with lye; 6. In order to successfully dry the pipeline, the pipe needs to be immersed in warm water or heavy steam dried out. Make the pipes dry; 7. Examine the pickled pipelines to see if they are clean; 8. Seal the opening of the pipe with plastic or plastic tape right away after marinading to avoid contaminant as well as wetness from intruding [1]



The steel pipelines that have been marinaded prior to pre-installation, and also the inner wall surface is free of corrosion and iron range; 2. Eliminate the pipelines as well as joints that require to be cleaned, and also use towel (( It is needed not to shed woollen). Use tidy water to remove the dust on the pipeline; 3. Wash with clean water For the attachments created in the above operations, the within of the pipeline ought to be cleaned with high-pressure water; 5. In order to effectively dry the pipe, the pipeline must be immersed in hot water or vapor dried.
