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

hRockwell hardness the Rockwell hardness test of stainless steel pipe is the same as Brinell hardness test. The difference is that it measures the depth of indentation. Rockwell hardness test is widely used at present, and HRC is second only to Brinell hardness Hb in steel pipe standards. Rockwell hardness can be used to measure metal materials from very soft to very hard, which makes up for the disadvantage of Brinell method,Stainless steel square tube It is simpler than Brinell method and can read the hardness value directly from the dial of the hardness machine. However,9cr18mov stainless steel plateThe quotation remains stable due to its small indentation, the hardness value is not as accurate as Brinell method.

However, some people will still ask whether our stainless steel pipes can be used as water pipes through online communication or telephone communication.

  — Cheap model (British and American), usually used as automobile exhaust pipe, is ferritic stainless steel (chromium steel).

sTherefore, there are requirements for the service environment of stainless steel, there are different tolerances for seamless hot expanded pipe,Stainless steel square tube seamless cold rolled pipe and welded pipe according to different dimensions. For example, for hot expanded pipe with diameter less than mm, when the thickness is mm and less, the upper limit tolerance of thickness is %; If the standard of stainless steel pipe is Chinese standard, according to the tolerance of stainless steel pipe for fluid transportation in gbt, the tolerance here is the tolerance when ordering according to the nominal thickness; According to the manufacturing method, the thickness standard of stainless steel pipe is divided into hot rolling and cold rolling, including thin plate with thickness of .-mm and thick plate with thickness of -mm. The specific gravity of stainless steel pipe is . The weight = specific gravity of length and width of thickness, and the weight of plate with thickness of stainless steel pipe of mm = m m = kg m (length) m (width) . M (thickness) (specific gravity) = . tons (weight)

: stainless steel wire: it can also be called stainless steel wire, coil rod and coil yuan,Stainless steel square tube but it is different from stainless steel wire rope. Wire rod mainly includes spring wire and screw wire. It specializes in selling special products such as stainless steel plate, stainless steel coil,9cr18mov stainless steel plateThe quotation remains stable stainless steel belt and stainless steel pipe. The old brand has advantages in price and guaranteed quality. As the name suggests: screw wire is mainly used to make screws, The spring wire is used to make springs or other hardware products required. Others such as bright wire, hydrogen withdrawal wire, electrolytic wire, axle hairpin wire, etc. the tensile strength is -. The hardness of spring wire is as follows: fully soft | / hard | semi hard | / hard | fully hard | extra hard. Steel wire rope gauge: * , * , * ,tisco stainless steel sheet,taigang stainless steel sheet,stainless steel sheet,stainless steel coil,stainless steel strip,stainless steel tube-TISCO Stainless Steel Co.,Ltd * , * , which is higher than that of wires, rods and tubes of the same material, stainless steel is a kind of high alloy steel that can corrode in air or chemical corrosion medium. Stainless steel has beautiful surface and good corrosion resistance. It does not have to go through surface treatment such as color plating but gives full play to the inherent surface properties of stainless steel. It is used in many aspects of steel, which is usually called stainless steel. Representative properties include chromium steel, - chromium nickel steel and other high alloy steels.

The Chinese brand of stainless steel plate is crnimoti (CrNiMoTi with paper should also be this brand). The new brand is crnimoti stainless steel plate. The stainless steel plate is added with Ti in SUS steel to improve the intergranular corrosion resistance. It is applied to the equipment of, phosphoric acid, acetic acid and acetic acid.

installrCorrosion resistance most stainless steel products require good corrosion resistance. Stainless steel pipe is similar to class I and II tableware, kitchen, 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, and determine the weight loss to determine the degree of corrosion.

CProduction process of stainless steel welded pipe: raw material - strip - welded pipe - end repair - polishing - Inspection (spray printing) - Packaging - shipment (warehousing) (decorative welded pipe).

Check the clamping forming effect after each clamping, and there shall be no clamping in place or serious depression of pipe clamping. According to visual inspection the pipe fitting end and the pipe are tightly bonded. The smaller the diameter of the diamond edge of the pipe fitting above DN is slightly smaller than the outer diameter of the pipe, ranging from .-mm. The larger the pipe diameter, the greater the difference.

vIn polluted air (such as atmosphere containing a large amount of sulfide, in case of condensate, acetic acid liquid points are formed, causing chemical corrosion.

qSAfter the installation of stainless steel water pipe cleaning pipeline, it is recommended to use % 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, imported steel pipes are also constantly impacting domestic steel enterprises.
