In fact, the corrosion resistance of stainless steel pipe is good because of the formation of a layer of purified film on the surface, in nature, it is in the form of a more stable oxide. But although the stainless steel tube according to the use of different conditions, the degree of oxidation is not the same, but the end are oxidized, this phenomenon is usually called corrosion.

“Firmly establish and practice the concept that green mountains are golden mountains, and plan for development at the height of the harmonious coexistence of man and nature.” Centerway Steel actively take action to “innovation” as a breakthrough, “quality” as the overall goal, and continue to promote carbon reduction, emission reduction, energy saving and other environmental protection and governance measures, writing the sky is more blue and the mountains are greener, high-quality and efficient development of the iron and steel answer sheet.

Excessive welding, simply put, is in the welding of stainless steel pipe, welding time is too long, welding heat input is too high or welding too many times, beyond the reasonable range of welding process.

304L stainless steel pipe: chromium (Cr) content is the same about 18% - 20%, nickel (Ni) content of about 8% - 10.5%, but the carbon (C) content is lower, not more than 0.03%. The lower carbon content is an important feature of 304L stainless steel pipe.

Dubai five industry exhibition - Middle East Dubai building materials exhibition (BIG5) is the Middle East region's most influential and is the largest construction, building materials and services exhibition. Started in 1980, while its derivative exhibition Middle East five industry construction machinery, vehicles and equipment exhibition (BIG 5PMV) is focused on the Middle East region construction equipment, machinery, tools and vehicles of professional exhibitions. Nowadays, the hot and continuous development of the construction market in the Middle East has driven the strong demand for construction equipment, materials, construction machinery and vehicles, and attracted more global attention.

304 stainless steel pipe has a long service life, from the use of stainless steel pipe in foreign countries, the service life of 304 stainless steel pipe can be up to 100 years, or 70 years, and the building is almost the same life. Of course, the premise is that the quality of 304 stainless steel pipe can not be too bad. 304 stainless steel pipe advantage is corrosion resistance, if the purchase of stainless steel pipe quality can be, in the use of the process of proper maintenance and cleaning, can effectively extend the service life of 304 stainless steel tube.

Stainless steel 304 steel pipe: high-quality materials and a wide range of applications, from the following four aspects of the detailed description: model specifications, material properties, product advantages and application areas.

Stainless steel 304 steel pipe material Stainless steel 304 steel pipe is a common stainless steel material, mainly composed of chromium and nickel. Among them, the content of chromium is 18% to 20% and the content of nickel is 8% to 10%. The material has good corrosion and oxidation resistance, and is able to keep its properties stable in high temperatures and humid environments.

Cold Rolling - Annealing Cold Rolling: It is the process of pressure and stretching ductility. Smelting can change the chemical composition of steel materials. Cold rolling can not change the chemical composition of steel, the coil will be placed in the cold rolling equipment rolls applying different pressures, the coil will be cold rolled to different thicknesses, and then through the last finishing roll, control coil thickness accuracy, general accuracy within 3 silk.

Spiral steel pipe is a strip steel coil as raw materials, regular temperature extrusion, according to the spiral shape of the bending molding, automatic double-wire double-sided submerged arc welding process for the inner seam and the outer seam welded spiral seam steel pipe. The raw materials are strip coil, welding wire and flux.

Straightening of LSAW steel pipe is an important process in the production of LSAW steel pipe. Especially for the higher quality requirements of API standard oil casing and oil and gas pipes, special pipes for machinery and equipment, these steel pipes not only have strict requirements on steel grade and weld quality, but also have high requirements on the straightness of the steel pipe, because the deviation of the straightness is directly related to the processing of threads and hoops at the pipe ends of the oil casing and transportation pipes, connection, and twisting deformation in the process of pipeline use.

Upgrading to high-end is the key path for Centerway Steel to enhance its core competitiveness. In the fierce market competition, only by continuously increasing the added value of products can we seize the market initiative.
