The surface of the steel strip in the state of supply shall be rough or bright.

The two ends of the 6m long steel pipe are mechanically cut,201 non magnetic stainless steel belt, and the pipe end is relatively sharp to prevent direct contact with the sealing ring of the pipe fitting. It is necessary to cut off a small section at both ends of the pipe or grind off the corner edge with a hand grinder, and then clamp the pipe fittings.

.Ferritic and martensitic stainless steels are represented by 400 series numbers. Ferritic stainless steel is marked with 430 and 446, martensitic stainless steel is marked with 4420 and 440C, dual phase (austenite ferrite).

SPCC stainless steel belt is simply an extension of ultra-thin stainless steel plate. It is mainly a narrow and long steel plate produced to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors.

.The pipes for pipe cutting shall be professionally cut by stainless steel. Rotate it for two circles, then slightly tighten the piece, and then rotate it for two circles until it is cut off. It must not be enough to allow personal strength to be in place at one time to lock the piece to cut off the pipe,345 stainless steel plate, otherwise the pipe end will be cut off, and the pipe fittings or rubber rings cannot be inserted; After the pipe above DN65 is cut, the internal and external burrs must be removed with a hand grinder, and an appropriate outer slope opening shall be opened at the same time to avoid damaging the sealing ring.

Seamless stainless steel pipe, also known as stainless steel pipe, is made of steel ingot or solid pipe blank through perforation, and then made by hot rolling, cold rolling or cold drawing. The specification of seamless steel pipe is expressed by outer diameter * wall thickness mm. With the implementation of China's reform and opening up, public buildings and tourism facilities have been built and a large number of urban houses, which puts forward new requirements for hot water supply and domestic water supply. In particular, people pay more and more attention to the problem of water quality, and the requirements are also increasing. Galvanized steel pipe a common pipe, will gradually withdraw from the historical stage under the influence of relevant countries because of its corrosivity. Plastic pipe, composite pipe and copper pipe have become common pipes in the pipeline system. However, under certain circumstances, stainless steel pipe has more advantages, especially the stainless steel pipe with wall thickness of only 0.6 ~ 2mm. In high-quality drinking water system, hot water system and water supply system that puts safety and sanitation first, it has the characteristics of safety, sanitation, environmental protection, economy and applicability. It has been proved by engineering practice at home and abroad that it is one of the new, energy-saving and environmental protection pipes with good comprehensive performance of water supply system. It is also a very competitive water supply pipe, which will play an incomparable role in improving water quality and people's living standards.

Shop around and choose affordable stainless steel water supply pipes. Comparing the prices of pipes sold by various companies, we should choose carefully and should not buy them. However, the transmission energy consumption of stainless steel pipe water supply pipe is low, so the price will not be too expensive.

Hot dip galvanized sheet hot dip galvanized sheet which immerses the sheet into the molten zinc bath to make its surface adhere to a layer of zinc. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in the zinc melting bath to make galvanized steel plate. Liaocheng Suntory stainless steel plate weighing method: 304 stainless steel plate: thickness (mm) x width (m) x Length (m) x density 316 stainless steel plate: thickness (mm) x width (m) x Length (m) x density 430 stainless steel plate: thickness (mm) x width (m) x Length (m) x density stainless steel basic weight (density)

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.

Cold drawn (rolled) seamless steel pipe: round billet → Heating → Perforation & rarr; Lead & rarr; Annealing & rarr; Pickling → Oiling (copper plating) → Multi pass cold drawing (cold rolling) → Blank tube & rarr; Heat treatment & rarr; Straightening & rarr; Hydrostatic test (flaw detection) → Mark & rarr; Warehousing.

A complete range of products.High temperature oxidation resistance stainless steel plates have high temperature oxidation resistance, but the oxidation rate will be affected by inherent factors such as environment and product form.

It has excellent stress corrosion cracking resistance. Even duplex stainless steel with low alloy content has higher stress corrosion cracking resistance than austenitic stainless steel, especially in the environment containing chloride ions. Stress corrosion is a prominent problem that ordinary austenitic stainless steel is difficult to solve.

The Chinese brand cold rolled non oriented silicon steel strip (sheet) represents: DW + 100 times of iron loss value (at the frequency of 50Hz, the waveform is sinusoidal, and the magnetic induction peak is 5T per unit weight iron loss value) + 100 times of thickness value. For example, dw470-50 represents cold rolled non oriented silicon steel with iron loss value of 7W / kg and thickness of 0.5mm. Now the new model is represented as 50W470.

Process inspection.National standard thickness of stainless steel pipe. Stainless steel pipe is a brand of stainless steel produced according to American ASTM standards. Before the national standard thickness of stainless steel pipe, there are stainless steel pipe national standard thickness national standard wall thickness table product name specification material price (yuan ton) rise and fall welded pipe 6 points 5mm (& phi; 275mm) 3850 + 30 welded pipe 1 inch 0mm (& phi; 330mm)

Application: utility boiler industry, mainly in key parts such as high temperature section of superheater and reheater.

After the installation of stainless steel water pipe cleaning pipeline, it is recommended to use 3% potassium permanganate for disinfection. It is strictly prohibited to use bleaching water for disinfection, and clean it with clean water after disinfection. If it is not put into use for a short time, compressed air must be used to blow out the residual water in the pipe, so as to prevent the corrosion reaction between oxygen free in the pipe and other media.

.  ·Sewage treatment system.

Stainless steel pipes are divided into hot rolled hot drawn and cold drawn (rolled) stainless steel pipes according to the connection and rolling process. According to the difference of stainless steel microstructure, they mainly include semi Ferritic and semi martensitic stainless steel pipes, martensitic stainless steel pipes, austenitic stainless steel pipes, austenitic ferritic stainless steel pipes,Stainless steel square tube 304, etc.

The shielding gas is argon with a purity of 999%. When the welding current is 50 ~ 50a, the argon flow is 8 ~ 0lmin, and when the current is 50 ~ 250A, the argon flow is 2 ~ 5lmin.
