Precision steel tube must raise service life. First, for precision steel tube in pickling passivation to get rid of the oxide skin appearance, then carry out RunHua solved, thus for pipes to carry out the acid treatment and passivation to generate a layer. Protective film. Then, according to the electrolytic process after pickling passivation fill, can further aluminium coated tubes maintain precision steel pipe, we manufacture precision steel pipe can be increased use of all the aspects of time and improve efficiency. Speaking of precision steel tube, believe that you should never feel strange!!!! If need to carry out the installation, it should do? Let's tell you specific precision steel pipe installation process.
A, the preparation of raw materials, special tools in advance
Ready to match the raw materials and special tools, and examine whether pairing.
Second, fitting laser cutting
15 to 50 mm pipe fittings used stainless steel plate technology professional knife, turning in circles again slightly tight head again several times until the disconnect, certainly will not be able to let oneself energy a clamping head broken pipe fittings in time, or we will cut the bad hydraulic steel tube can not be inserted into the pipe or plug and seal ring; DN65 more fitting must use hand mill after laser cutting remove burrs inside and outside, and at the same time open moderately outside weld in order to prevent the injury sealing ring.
Three, connected into
1, inserted into the pipe before, first to do deep the identity of the line on the pipe, thus avoiding no conformity in time.
2, clear to be inserted into the pipe inside and grease and dirt, keep clean inserted into the pipe connecting pipe.
3, check the pipe sealing ring can be detailed cleaning, if placed stainless steel tube 304 where appropriate. If there is a waste material must be clean and tidy, sealing ring, if produce damage must be changing again.
4, the pipe must be facing fitting slow turning into, insert the relatively tight, please use wet pipe and sealing ring and plug into clean water. 5, 6 meters on both sides of the stainless steel pipe is laser cutting machinery equipment, hydraulic pipe is relatively sharp, avoid would destroy insert pipe sealing ring. Must first cut on both sides of the tube with a knife to remove a small section or by hand grinding machine grinding Angle front, then inserted into the conformity of pipes.
Precision steel tube welding plan and high carbon steel is also commonly before welding. Should pay special attention to is that we should pay attention to solve the weld specification and hot dip galvanized layer surrounding the. In order to better enough welding welding, weld specification as much as possible, generally is 60 ~ 65 °, and shall set aside a certain gap, general is 1.5 ~ 2.5 mm; In order to lower the infiltration of zinc in welding in the welding welding to hot dip galvanized layer in slope mouth.
On site supervision work, choosing didn't leave the centralization of the blunt Cold Drawn Seamless Tubes edge weld centralized control system, choose double welding method, the probability of lower under welding. Wire should be original material selection on the basis of precision steel pipe. In general, facilitate J422 with its actual operation and is widely used to high carbon steel.
Because we all choose the precision steel tube, and its usage is expected to flow. How to better use of precision steel tube? Which requires you to carry out precision steel tube production process, flow to the use of precision steel pipe.
We manufacture precision steel tube is made of different materials, and its elements, of course, is not the same. Usually, everyone's precision steel tube is not easy to rust. But this is not because of the precision steel tube is not easy to rust, so we don't usually pay attention to it. Can we sit down and make us sit down and release pressure.
