Precision steel tube is a kind of very main pipe type, in many cases are all can use, in general, precision steel pipes in the engineering construction to pay more attention to all kinds of engineering construction, also need to pay attention to material selection, generally all is to use, especially in road construction, bridge construction and its industrial factory building and plant in basic side impact door beams construction can be used. Precision steel tube with the aid of is a traditional handicraft, according to the physical and working pressure and have strong working ability of the corrosion resistance and resistance to acid alkali, so precision steel tube under the condition of all kinds of natural environment can be used.
The characteristics of the precision steel tube is of high precision, and is not easy to rust. But is not to say that since precision steel tube is not easy to rust at ordinary times they will take care of it, put it away immediately. That would be wrong, because if precision steel tube at ordinary times is not maintenance, it will reduce the use of the time limit, also can cause unnecessary damage to precision steel pipe. Customers choose and buy of precision steel tube must expect to use time limit may be longer, so we need to pay attention to peacetime precision steel pipe maintenance.
In order to better improve precision steel pipe corrosion resistance, general precision beam impact tubes steel pipes need galvanizing. Precision steel tube is divided into hot dipped galvanized and phosphating. Hot dip galvanized layer thickness, phosphating low-cost, surface is not too bright and clean. Oxygen pipe: steel blowing. Application of small diameter welding pipe, usually eight kinds of specifications for 3/8-2 feet. It consists of 8, 10, 15, 20 or 195 - q235 steel strip. In order to avoid erosion, some should be aluminum plating film reasonably.
Most of the old house application precision steel pipe. Now for the natural gas and heating galvanized pipe and precision steel pipe. Water pipe precision steel pipe. After years of application, can cause a lot of rust scale line. Yellow fluid not only environmental pollution sanitary ware, and uneven basking in its inner cavity the bacterial virus mixture. Caused the water erosion of metal elements is high, a serious threat to people's physical and mental health. The 20th age 60 s and 70 s, the global capitalism country has just started to develop the new line, and it is forbidden to application of precision steel tube in succession. Chinese ministry of construction and other four BuWeiJu established show that since 2000, precision steel tube has been banned. Cold water pipes at present, the newly created residential quarters is very little use of precision steel tube, part of the residential area of central heating conduit choose precision steel pipe.
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 edge weld centralized control system, choose double welding method, the probability of lower under welding. Wire should be original material selection beam impact tubes 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.
