3, a cross between a parallel or piping, there should be more than 10mm gap.
4, configure the pipeline must make hydraulic valves, piping and other components handling, easy maintenance. Any component or piping system should be able to freely removable
without affecting the other components.
5, when the pipe so that the pipe must have a certain degree of anti-vibration and rigid capacity. Properly configured pipe clamps and pipe supports. Bent pipe bracket or pipe
clamps should be located near the starting point of inflection. Not with a stent or conduit pipe clamps welded directly.
6, should not bear the weight of the pipe by the hydraulic valves, hydraulic pumps and other hydraulic components and accessories; nor shall a heavier element weight bearing
pipes.
7, a longer pipeline must consider effective measures to prevent temperature changes caused by stress telescopic tube.
8, the pipe material used must have a clear basis of raw materials, for unknown pipe materials are not allowed.
9, the hydraulic system in the available wheel 50mm diameter tubes following cutting machine. 50mm diameter pipe above general machining methods should be used to cut. As with
gas cutting, machining methods must be used due to changes in the car to gas cutting formed part of the organization, while the car out of the welding groove. In addition to the return line,
the pressure pipe is not permitted by the squeeze roller cutter cutting. Pipe cutting surface must be flat, deburring, descaling, slag and so on. Cut surface should be perpendicular to the tube
axis.
10, a pipe routing multistage pipe and fittings shall be composed of piecewise turn over, completed a period, after assembly, and then configure the subsequent period, in order
to avoid a complete welding cumulative errors.
?11, in order to reduce local pressure loss, pipeline segments to avoid a partial sectional dramatically expand or narrow and sharply bent.
12, tube and pipe fittings or flange connection must be a straight pipe, that this should be the axis of the pipe fittings, flanges axis is parallel to coincide. This line
segment length is greater than or equal to 2 times the diameter.
13, the outer diameter of less than 30mm of pipe can be cold-formed method. Pipe diameter can be cold-formed or bending method at 30 ~ 50mm. When the pipe diameter greater than
50mm, bending method generally used.
14, welders welding hydraulic pipes should have a valid high pressure pipe welding certificate.
15, welding process selection: acetylene gas welding of carbon steel is mainly used for general 2mm wall thickness of less than or equal tube. Arc welding is mainly used for
carbon steel pipe wall thickness greater than 2mm tube. TIG welded pipe is best to use. Pipe wall thickness greater than 5mm backing should adopt welding, arc welding filled. Necessary
occasions should be used to protect gas pipe hole filling method of welding.
16, the electrode, the welding flux should match the pipe, the grade must have a clear basis of information, product certification, and the effective use period. Welding, flux
before using the instructions provided its products should be dried and kept dry during use, for use in the same day. Electrode Coating should be no loss and significant cracks.
17, a pump station pipe welding should butt welding. Before welding groove and its vicinity should be 10 ~ 20mm wide at the surface dirt, traces of oil, water and rust, etc.
cleaned.
18, welded pipe and flange should butt welding flange, non-use plug-in flange.
19, welded pipe and butt-welded joints should be used, not be used in the form of plug-in.
20, welded pipes and pipe should butt welding, soldering not allowed to use the plug-in form.
21, when the hydraulic pipes butt welding, weld must be higher than the inner wall of the pipe 0.3 ~ 0.5mm. Recessed wall phenomenon is not allowed. After the solder, and then
filing or hand wheel the inner wall above the weld repair level. Removing welding slag, burrs, to achieve a smooth level.
22, butt weld pipe cross-section should be perpendicular to the centerline.
23, the weld cross section is not allowed in the corner, it should also be avoided between two elbow pipe.
24, welding pipe, you must press the installation location spot welding position, then remove to welding, the welding assembly after shaping.
25, welding the whole process, should prevent wind, rain, snow invasion. After the pipe welding, the wall thickness of less than or equal to 5mm weld, should be cooled at room
temperature, not use strong wind or water spray forced cooling.
26, the weld penetration should be, should be uniform smooth appearance. Weld pressure pipeline testing and inspection should be sampled.
27, conduit pipe welding after all pipes are pre-installed location should once. Each hydraulic components, valve block, valve frame, pumping stations connected. Each interface
should be a natural fit and, for the connection is not strong twist. When you release the fittings or flange screws, the relative binding surface centerline not allowed to have a larger
displacement, from the angle of the seam or Rocker. In such event available roasted shaping eliminated.
28, can be completed after all the pipe weld pipe clamps and racks can also be carried out according to the needs of post *.
29, conduit piping, welding, after the pre-installation, re-open the pickling phosphating. After the acid phosphate by pipeline to pass into the hot air pipe for quick drying.
After drying, as in a few days to re-loaded into the system, which leads to the inner tube of hydraulic oil, usually do not make anti-rust treatment, but should be kept properly. As to be
shelved indefinitely, you need anti-rust coating paint, it must handle the 48 hours before painting after phosphating. It should be noted, anti-rust coating must be compatible with the cleaning
solution or pipe cleaning after use of hydraulic oil.
30, before the pipeline in acid, phosphate, install it again after drying, the need for each of the pipe wall to conduct a pre-cleaning. After the pre-cleaning is completed as
soon as possible to re-install the system, the system's overall circulation purification, until the required cleanliness level system design.
31, Hose limited to the following situations: ---- ---- equipment between the movable element to facilitate the replacement of the replacement parts
---- Mechanical vibration or noise suppression at delivery
