Stainless steel water supply pipe is a healthy economic, whether it is for household or large engineering buildings

The requirements for weldability and weldability vary from product to product. A tableware usually does not need welding performance sanitary and energy-saving water pipe, and even includes some pot enterprises. However, most products require good welding performance of raw materials, such as class II tableware,Stainless steel pipe manufacturer, thermos cup, steel pipe, water heater, water dispenser, etc.

.At the same time, the Ministry of construction attaches great importance to the application of stainless steel pipes. The industry standard of stainless steel water pipe was issued and implemented in 2001. The Ministry of construction has issued documents on relevant technical specifications and installation sets of pipeline engineering, which are being prepared by Tongji University. All kinds of stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe are qualified. Welcome to telephone inquiry and sincerely invite cooperation! At present, there are stainless steel pipes in Sichuan, Guangdong, Zhejiang, and the products have become mature. Therefore, the time for application has come.

Stainless steel pipe national standard thickness in the stainless steel pipe industry, the steel that meets the national standard is generally called & ldquo; National Standard & rdquo; Inferior steel that does not meet national standards is called & ldquo; Winning the bid& ldquo; Non standard & rdquo; In practical application, the quality of national standard and non-standard is similar, mainly due to the difference in thickness. A thickness of national standard is actually 1mm, but a thickness of non-standard is actually only 0.8mm or other thickness less than 1mm. Non-standard is basically equivalent to winning the bid. Standard index size (323mm) label number standard implementation standard gbt14976-2012 non-standard specific thickness ratio outer diameter steel pipes are produced according to the standard. 2 non-standard belongs to customized difference. Wood office says ha ha customized on demand. 3 thickness area: the difference between standard, thickened, 15 9 large plants and 18 8 large plants of national standard and 18 8 small plants of American Standard 132@_ @ The national standard contains more than 17 chromium and the American Standard contains more than 18 chromium@_@ Stainless steel pipe is an American Standard, not in the national standard. The corresponding national standard is 06cr19ni10.

.& Ge; about 40 thickness: cold rolled 2B plate (0.09 & mdash; 0mm); hot rolled industrial plate No.1 (3-50mm) medium plate, chemical plate and high temperature plate; width: 5mm --- 850mm steel strip; 1000, 1500, 1800 and 2000mm coil plate and flat plate surface: 2B smooth surface, No.1 industrial surface, BA (6K) mirror, 8K mirror, 9K mirror, wire drawing surface and frosted surface.

The inner and outer surfaces of precision stainless steel pipe and thick wall pipe shall be free of cracks, folds, crazing, cracks, rolling folds, delamination, scabs and other defects, which need to be completely removed (unless they are specially used for machining) And after removing the stainless steel pipe wall, the wall thickness and outer diameter shall not exceed the negative deviation. As long as some minor surface defects that do not exceed the allowable negative deviation do not need to be removed.

Stainless steel pipe appeared in Foshan, Guangdong Province in the tenth generation of the last century. With the rapid development of science and technology in recent decades, stainless steel pipe production is all over the country. Stainless steel pipe is more and more widely used. But in fact, most people, including many people in the industry, do not know much about the classification and application of stainless steel pipes. Take stainless steel pipe for example.

As we all know, stainless steel pipe has a strong ability of atmospheric oxidation and is not easy to rust under normal circumstances, & ldquo; Stainless steel pipe & rdquo; Hence the name of. But what I want to tell you today is that stainless steel pipes will also rust. I believe many friends will be surprised! I believe there are many people who don't know how to explain to customers! Next, let's popularize science!

The selection of pipes and fittings for welding data preparation shall be based on the quality elements of the application environment, chemical composition and application pressure, and the commodities of corresponding grades shall be selected to ensure the weld metal structure and machine function.

Clamping operation the jaw of the caliper must be placed perpendicular to the axis of the pipe and pipe fitting, and the convex ring of the pipe fitting needs to be put into the groove of the jaw for clamping. In order to prevent operation, the operator can only stand on the axis of the pipe not on the left and right sides of the tong head.

High value.The specification and appearance quality shall comply with the provisions of gb14975-2002 stainless steel seamless steel pipe. The steel pipe is usually 5 ~ 10m long (indefinite length) hot rolled steel pipe, 0 ~ 7m; the wall thickness is greater than 0mm, 5 ~ 8m.

In order to prevent the occurrence of welding pores,Centennial stainless steel water pipe, the welding parts must be cleaned if there is rust, oil stain, etc.

Corrosion resistance most stainless steel products require good corrosion resistance. Stainless steel pipe is similar to class I and II tableware kitchen,Stainless steel 304 water pipe, water heater, water dispenser, etc. Some foreign businessmen also test the corrosion resistance of products: use NaCl aqueous solution to warm to boiling. After a period of time, the solution is to drain, wash and dry, when selecting the reasonable thickness of the steel plate, its service time, quality and stiffness should be considered, and the strength requirements of the plate under pressure should be considered; Thermal conductivity; Distribution of pressure and format specification of pressing plate.

reform.When transporting domestic and drinking water, the pipeline shall not pass through the toxic pollution area. If necessary, protective measures shall be taken.

Austenitic stainless steel heat treatment austenitic stainless steel commonly used heat treatment processes are: solution treatment, stabilization treatment and stress relief treatment.

It has good local corrosion resistance. Compared with austenitic stainless steel with the same alloy content, its wear-resistant corrosion and fatigue corrosion properties are better than austenitic stainless steel.

.Good corrosion resistance, suitable for a variety of media; The addition of Mo improves the corrosion resistance to reducing salts; It is resistant to marine and industrial atmospheric erosion, and can be used in seawater equipment; Due to its low carbon content it has excellent grain boundary corrosion resistance; It can be used in pulp and paper machinery; Good processability and weldability.

In order to prevent the occurrence of welding pores, the welding parts must be cleaned if there is rust, oil stain, etc.
