Construction materials shall be prepared and delivered to the site according to the data scheme, cold-rolled pipe, cold drawn pipe and pipe. Cold drawing and cold rolling are the secondary processing of steel pipe; Welded pipe is divided into straight seam welded pipe and spiral welded pipe.Soligorsk,There are ba face, b face, (white skin), (frosted), HL (wire drawing), K face and other surfaces with good quality and brightness.Model & mdash; Martensite (high strength chromium steel),Body austenitic stainless steel seamless steel pipe and welded steel pipe stainless steel pipe for mechanical structure stainless steel pipe for ordinary pipe stainless steel pipe for boiler, stainless steel pipe for heat exchanger and seamless steel pipe for chemical industry (crnit) qhyad crnimosi duplex stainless steel seamless steel pipe. Stainless steel is mainly used in the automobile industry, accounting for more than % of the total consumption of automobile stainless steel, and % is ferritic stainless steel. The exhaust gas produced by automobile engine is from the rear of intake pipe, front pipe, hose, converter and center pipe. The common steel grades of exhaust system are L l, etc. it is mainly used in automobiles Stainless steel welded pipe. It is estimated that the stainless steel pipe used in automobile accounts for about % of the consumption of stainless steel pipe in the whole downstream. L stainless steel pipe, s stainless steel pipe and L stainless steel pipe are provided for a long time. The products are complete, excellent quality and favorable price. The use ratio of stainless steel pipe and welded pipe is about :.Accounting for about % - % of the total steel, it is widely used in the national economy. Because the steel pipe has a hollow section, compared with the round steel of the same weight, the steel pipe has large section coefficient and high flexural and torsional strength, so it has also become an important material in various machinery and building structures. Stainless steel is used Under the condition of equal weight, the structure and components formed by pipe have a larger section modulus than solid parts. Therefore stainless steel pipe itself is an economic section steel that saves metal. It is an important part of steel, especially in oil drilling, production and metallurgyStainless steel export is an important part of China's export economy. It plays an important role in stimulating China's economic growth. However, from the current situation of China's stainless steel foreign trade, China's stainless steel export has encountered great resistance.

Stainless steel seamless steel pipe for structure (instead of gbt-)(VI) the growth rate of fixed asset investment in the iron and steel industry dropped significantly. From to June, the investment in fixed assets in the iron and steel industry was . billion yuan, a year-on-year increase of %, of which the investment in ferrous metal smelting and rolling was . billion yuan, a year-on-year increase of %, down percentage point from the same period in ; The investment in ferrous metal mining and dressing was . billion yuan, a year-on-year increase of %, and the growth rate fell sharply by percentage points.;- Ferromagnetism due to m transformation shall be considered in use (such as in instrument parts).Safety production,The slab solidified on the surface continues to be rapidly cooled through the secondary cooling section until the core becomes solid, and the whole continuous casting process of stainless steel pipe fittings is completed.Inspection: after crimping, check the crimping size with a special gauge. & mdash; high strength cutting tool steel, with slightly higher carbon content,SoligorskService life of stainless steel pipe, can obtain higher yield strength after appropriate heat treatment, and the hardness can reach hrc. It is one of the hard stainless steels. A common application example is & ldquo; shaving blade & rdquo;. There are three common models: C and f (easy processing type).

Adjust the ratio of austenite forming elements to ferrite forming elements in the steel to make it have austenite + ferrite dual phase structure in which ferrite accounts for % - %. This dual phase structure is not easy to produce intergranular corrosion.install,The protection mechanism of stainless steel backing wire + TIG process is that the back weld is protected by the metallurgical reaction of slag produced by welding wire melting and its alloy elements, and the front weld is protected by argon, slag and alloy elements.Corrosion test: the industrial corrosion-resistant steel pipes provided shall be tested for corrosion resistance according to the standard provisions or the corrosion agreed by both parties and there shall be no tendency of intergranular corrosion.For business people,Soligorsk316L stainless steel pipe,Soligorsk306 stainless steel pipe, of course, it is better to spend less under feasible conditions. For goods such as stainless steel pipes, we can often see that there will be packaging film bags on them. Although they are not heavy, if there are a large number of single purchases, they will also produce certain economic expenses, but why do many people clearly dislike this thing on stainless steel pipes, But I have to accept it. Next, xincoral Xiaobian will tell you why stainless steel pipes need packaging bags.Soligorsk,Raw materials -- strip splitting -- welded pipe making -- heat treatment -- Correction -- straightening -- end repair -- pickling -- Hydrostatic Test -- Inspection (spray printing) - packaging -- delivery (warehousing) (pipes for welded pipe industrial piping).The operators are mainly plumbers and argon arc welders, with the cooperation of other types of work, and the argon arc welder shall have the certificate issued by relevant departments.When using this method, it should be noted that the water-soluble paper should be double-layer and must be pasted well, otherwise it is easy to cause damage and fall off of the water-soluble paper, resulting in loss of argon protection of the inner weld and oxidation, resulting in cutting of the weld junction and re welding, which can not ensure the welding quality and seriously affect the construction period. Therefore, the water-soluble paper should be strictly checked and pasted before welding.
