Stainless steel square tube is a hollow steel strip, so called because of the cross section is square tube. Many pipeline used for conveying fluid, such as oil, natural gas, water, gas, steam, etc., the other, doing bending and torsional strength together, weight is lighter, so it is widely used in manufacturing machinery parts and engineering structures.
One, the Angle is introduced: the Angle x52 line pipe steel is generally referred to as the Angle, and it is a belt of ChangGang, two perpendicular to each other. Angle can be based on the different needs of structure is composed of all kinds of bearing components, can also be used as a component of cohesion between. Widely used in various kinds of building structure and engineering structure, such as computer room beam, Bridges, transmission tower, lifting transportation machinery, ships, industrial furnace, reaction tower, container frame, in cable trench stents, electric pipes, bus exhaust device, and warehouse shelves, etc
Angle first divided into two kinds: equal Angle range and Angle. Meanwhile, unequal Angle can be divided into marginal thickness is not equal and marginal thickness is not equal to two.
Peer, equal Angle on both ends of Angle steel, x56 line pipe its standard around around to face width around * width * thickness of surface of mm. For example: 30 * 30 * 3, indicate the equilateral Angle steel, its surface width is around 30 mm, and the surrounding surface thickness is 3 mm. Also can use model (number) indicate, during which model is the face width on the number of centimeters around. Can add symbols "<" in front of the Angle steel model, add the symbol "#" in the upper right corner of your model, for example: < 30 #. Equal Angle steel standard planning for # 2 - # 20.
Stainless steel tube of the polishing process is carried out on the tube surface cutting process, using optical materials, optical instrument and friction on the surface of the pipe, reach the cutting on the surface of the pipe, to get the corresponding light noodle.
Light steel pipe, there are list of the points of light. Existing outside alone with different coarse-grained linen wheel or emery cloth wheel combination of light, to get the corresponding light noodle. Term is on the inside of the pipe with plastic grinding head (cover cloth) reciprocating or rotary movement, for cutting pipe list table.
The content of chromium stainless steel plate is 18 to 19, the content of NI is 8.0 to 8.9, because the nickel content is higher in terms of corrosion resistance greatly enhanced, used in general environment can keep more than 15 years of time, in harsh environments (such as coastal areas, industrial pollution serious areas) can maintain 5 years or so. Many users think that stainless steel plate is rusty quality has a problem, actually this is a one-sided understanding, they are only stainless steel corrosion resistant ability is stronger. Shenyang stainless steel plate
Burnt heating temperature is exorbitant, not only cause x60 line pipe the austenitic grain bulky, and grain boundary part oxidation or melt, lead to grain boundary weakening, called burnt. So in the work to prevent the formation of burnt. High temperature resistant stainless steel decarburization and oxidation of stainless steel tube during heating, the surface of medium carbon and oxygen, hydrogen, carbon dioxide and water vapor reaction, down the surface carbon concentration, called decarburization, decarburization stainless steel after quenching surface hardness and fatigue strength and wear resistance to drop, and the tensile stress in the surface constitute the rest easy constitute mesh surface crack.
