Materials Used in Stainless Steel Welded Tube
The main raw material of stainless steel welded pipe is stainless steel plate and strip. Stainless steel strip is a thin plate material made from stainless steel through continuous casting, rolling, annealing and other processes. Stainless steel plates and strips have the characteristics of corrosion resistance, high temperature resistance, high strength, and wear resistance, so they are very suitable as raw materials for stainless steel welded pipes.
The main components of stainless steel strips are alloys of iron, chromium, nickel and other elements. Among them, chromium is the most important alloying element. It can react with oxygen to form a dense chromium oxide protective film, which prevents stainless steel from being corroded. Nickel can improve the toughness and corrosion resistance of stainless steel. In addition, there are some other alloying elements, such as molybdenum, vanadium, titanium, etc., used to improve the special properties of stainless steel.
When manufacturing stainless steel strips, the raw materials need to be smelted first, usually using an electric arc furnace or an induction furnace. The smelted stainless steel liquid passes through the continuous casting machine and is cooled into a cast slab. The slab is then rolled through a rolling mill into the desired strip shape. In order to improve the performance of the plate and strip, annealing is usually required to eliminate stress and improve toughness.
The stainless steel strip is cut and formed into the mother pipe of the stainless steel welded pipe. Then, the mother pipe is welded into the desired pipe shape through a welding process. There are many welding processes, the common ones are tig welding1, mig welding2, etc. After welding is completed, surface treatment, such as deoxidation, sandblasting, etc., is required to improve the surface quality of the stainless steel welded pipe.

In the production of welded stainless steel pipe, the first step is to identify the material of stainless steel plate. Determine the stainless steel pipe material and the circumference of the steel pipe, while purchasing the corresponding material, width and steel plate perimeter of the same level of stainless steel plate. Enter the production site after surface inspection of steel plate according to the forming of the steel plate, steel plate or oxide scale is determined, no pits or less cellular, and less area of on-site grinding or sandblasting. Nondestructive testing followed by the end of the plate, here is generally used in penetrant inspection, is the first to end with a cleaning agent for cleaning and dry, then spray stains, wait a few minutes later, wipe the stains, spray on the imaging agent, wait a few minutes after the end of observation is there red lines to confirm whether there are defects in stainless steel plate. Then the steel plate on both sides or a single side of the ultrasonic testing, ultrasonic wave to determine whether the steel plate defects.
The steel plate after the test is finished, the second step is the first rolling, rolling machine press select the corresponding arc, and then put into the steel plate rolling machine under rolling, the stainless steel plate rolled into a cylindrical slowly. Followed by the third step of the pre welding, pre welding, if the machine is submerged arc welding, but also must be welded at both ends of the steel arc plate, and then welding.
The welding process is divided into priming and filling and cover. After the completion of welding work, is to do ndt, for ray by rt ray of steel pipe welding, welding internal confirmation does not appear root not melting, unweld, welding slag, stratification, large quantities of gas welding defects. Then the pipeline pressure test process, in accordance with the design pressure of 1.5 times the water pressure test of the pipeline, to ensure that the pipeline under the pressure intensity, no structural deformation of the pipeline, no leakage, pressure to maintain stability, etc.. Finally, the heat treatment of steel pipe welding, after a period of time so that the temperature between the weld to maintain a heat treatment temperature value of a few minutes to half an hour, and then slowly cooling, the production of steel pipe is basically completed. The remaining task is to carry out the identification of pipeline spraying and anti-corrosion work. The contents include the name of the manufacturer, the specification of the pipe, the material of the pipeline, the batch number of the pipeline, and the corrosion grade requirements of the pipeline.
After a series of work, a small steel plate into a gas, liquid and other media to the pipeline. In order to ensure the quality of the pipeline, before leaving the factory, but also the need for review of pipeline materials, usually on the same batch of pipeline inspection, the spectral and hardness of the review. Then check the size of the pipeline, and finally signed on the production list to complete.
How to Maintain Stainless Steel Welded Tube
Stainless steel welded pipe in the modern industrial production and life, more and more people are used to investigate the main reason is that the characteristics of stainless steel welded pipe, it is more convenient to use, but also economic and environmental protection. So how to maintain and maintain it, so that it can better serve our work, I believe that many people want to know.
For in the interior of the stainless steel welded pipe, in use should pay attention to the following to avoid and don't, stainless steel welded pipe and the like things, should avoid and chlorine ion contact, in daily welding and machining process, in order to protect our stainless steel welded pipe, we should try to avoid cutting is iron filings produced sparks, try to avoid friction and iron like stuff. The use of the process, should pay attention not to contact with all kinds of things, such as sulfuric acid, nitric acid and so on, organic acid is also not. Usually we use the debris is a lot of, should be careful to avoid the cement and lime contact, as far as possible to reduce pollution. Clean the process, but also to avoid the use of sewage and cleaning detergent for cleaning.
For external use of stainless steel welded pipe, the general should be washed two times a year. Outside of the stainless steel welded pipe generally have the effect of rain water erosion. And the artificial cleaning is combined with the rain water erosion. Artificial cleaning using a sponge dipped in soapy water to clean the water. In general, the combination of rain washed and manual cleaning, the surface of the stainless steel welded pipe dust has a good effect, can maintain the perfect surface of stainless steel welded pipe.
Is the first come into contact with stainless steel welded pipe industry, just know it is not only used for machinery, automobile, also be very ordinary used in bicycle, furniture, hotel, housing decoration and other mechanical components and structural parts. It is also very amazing to be able to have such a wide range of applications, and also want to know more about it, especially in terms of maintenance and maintenance.
In fact in normal shops and selling stainless steel cleaning powder. It is mainly used to remove the stainless steel welded pipe surface of stubborn spots and stains. Use the time as long as directly on the surface of the stainless steel welded pipe dirt, wait 3 minutes later, washed with water, you can restore the bright as new. However, this method only applies to some small things, a month to clean, you can maintain a clean stainless steel welded pipe.
