Q:What does "stainless steel pipe" DN mean?
In order to connect the pipe and pipe fittings in a unified way, nominal diameter (also called nominal diameter, nominal diameter) is adopted. For example, welded steel pipes can be divided into thin wall steel pipes, ordinary steel pipes and thickened steel pipes according to their thickness. Its nominal diameter is neither external diameter nor internal diameter, but a nominal size similar to the diameter of the ordinary steel pipe. Each nominal diameter corresponds to an outer diameter, and the inner diameter varies with the thickness. Nominal diameter can be expressed in metric mm, also available in English in. With nominal diameter pipeline accessories, meaning with tube.
Q:Does stainless steel pipe belong to hardware?
Belong to. Hardware: refers to gold, silver, copper, iron, tin, five metal materials called. Stainless steel pipe is a kind of hollow long strip round steel.
Q:Mechanical properties of stainless steel tubes
Strength (tensile strength, yield strength) the strength of stainless steel is determined by various factors, but the most important and basic factor is the addition of different chemical factors, mainly metallic elements. Different types of stainless steel have different strength characteristics due to their differences in chemical composition.
Q:How much more expensive is 304 stainless steel than 201?
201 in the stainless steel industry, represents a kind of material, 201 stainless steel is generally refers to 201 stainless steel and acid resistant steel floorboard. 201 stainless steel refers to the atmosphere, steam, water and other weak medium corrosion of steel, while acid resistant steel refers to acid, alkali, salt and other chemical corrosive medium corrosion of steel.
Q:Stainless steel works. What saw can be sawed off?
What is the best or bad, to the building materials market to find a store with a chainsaw to help cut or site also if things go to the talent market, a hydraulic, electric what, give him a little money he will help you cut out
Q:Is galvanized steel pipe stainless steel pipe?
Galvanized steel pipe is a kind of welded steel pipe, and its essence is hot-dip galvanized coating on the inner and outer surface of welded steel pipe. Hope to be of help to you.
Q:Why is the outer diameter of 1 inch galvanized pipe 33.7? And the outer diameter of one inch stainless steel pipe is 25.4
Some 25.4 such outer threads, is the imperial Whitworth Thread and American Standard unified thread, single head wire estimate.
Q:What is the difference between the stainless steel tube and tube rolling
We usually say the hot-rolled seamless slide into thermal expansion, is to use tools of the pipe up, supporting circle. Cold is the opposite, a fixed mould outside the inner hole of the fixed mandrel, from the outside to make him thinner. Annealing is required before hot rolling, without cold rolling. In hot rolling billet after annealing, stainless steel seamless pipe, wall production minus a broaching machine after reaming compression capability, good flexibility, technological properties were superior to those of ordinary tube ligation.Now the Zhejiang area in the production of stainless steel seamless pipe is widely used cold production technology, but higher production efficiency of 2 roller cold rolling mill, a lot of strength of the manufacturers are equipped with, because the price of the purchase quantity not more general factory. It is commonly used in conjunction with cold drawn units to increase efficiency and reduce production costs.It is precisely because of their differences in production and processing technology, but also makes the hot-rolled stainless steel and cold-rolled pipe has the following differences:A: seamless pipe and tube rolling produced products, though they are working with the tube, but the application is different, generally used for mechanical drawing, heat exchanger pipe, pipe and tube rolling engineering, generally used for fluid transport in pipeline construction;Two: seamless pipe and tube rolling process and product quality; slide processing, low defect, high precision, uniform grain size;Three: two different prices, the price to slide rolling ratio is more expensive;Four: the stainless steel tube ligation can only in diameter 38-159 pipe, or other drawing process. Because of the production process, the tube size is relatively accurate. In the purchase of steel tubes, or tube rolling is drawing, but also the actual situation needs to choose.
Q:Stainless steel pipe pickling ratio
Usage: apply proper amount of this product onto the surface of stainless steel to be processed, the thickness of 1~2 mm, 5-30 minutes or longer (by dirt, sheet materials and processing requirements), process the best brush a few times, the surface oxide skin, rust completely clean, with water (lime water or salt water better) rinse, avoid rust.
Q:Stainless steel pipe chamfering how to process?
The use of fast machine chamfering is the trend of mechanical industry. The utility model overcomes the defects of the processing of the existing machinery and the electric tool, and has the advantages of convenience, quick and accuracy, and is the best choice for chamfering the metal object at present. According to the chamfer, it needs to be divided into straight line, chamfer and curve chamfer.
