Practice has proved that almost all oxide scale, rust and other dirt can be removed by using this derusting grade, and the depth of anchor grain can reach ~ & mu; m, which fully meets the requirements of adhesion between layer and square pipe The shot derusting process can meet the technical conditions of near white level (SA) with low operation cost and stable and reliable quality.Mocha,Chemical polishing: less investment in processing equipment, high speed, high efficiency and good durability. Its defects are poor brightness, gas overflow, demand for ventilation equipment and difficult heating. It is suitable for processing small batch of disordered parts and products with low brightness demand for small parts.Precision pipe is a seamless pipe with high dimensional accuracy and good surface finish for mechanical structure and hydraulic equipment. The selection of precision seamless mechanical structure or hydraulic equipment can greatly save machining hours, improve material rate and improve product quality. Seamless pipe can be divided into hot rolled pipe and cold rolled pipe according to different productionBure,For structure: as pile driving pipe and bridge; pipe for wharf, road and building structure, marine pile driving pipe, etc.Square tube is an essential material for the construction and Realization of industrialization. It is widely used and has a wide variety. According to different section shapes, square tube is generally divided into sections, plates, pipes and metal products. In order to facilitate the production, ordering and supply of square tube and do a good job in operation and management, it is also divided into heavy rail, light rail,MochaGalvanized square pipe schedule, large section steel, medium section steel, small section steel and square tube cold bending Section steel, high-quality section steel, medium and thick steel plate, sheet steel, electrical silicon steel sheet, strip steel, seamless steel pipe, square pipe, welded steel pipe, metal products, etc.For improper stamping direction, simulation software shall be used in the initial stage of design to ensure that the direction of stamping parts is analyzed, the direction shall be adjusted to seamless square tubes. The square tube manufacturer introduces the forming, bending and bending of square tubes. As the name suggests, the bending is compacted, and the inner and outer rollers are double with the inner and outer walls of tube billets during actual bending Compact towards the.

Steel for construction and engineering according to the classification of use without phase transformation or partial phase transformation of square tube: A. ordinary carbon structural steel; b. Low alloy structural steel; c. Steel reinforcement.The difference between qb square tube and QA is that there are fewer impurities s and P and better low-temperature impact performance. From the welding point of view, when the impurity elements in the base metal are less, it is good for welding hot crack.Engaged in square tube, square rectangular tube, seamless square tube galvanized square tube, galvanized tube, price advantage and quality guarantee! However the Demander shall cut off the interface pipe when using it. The weight of short length and non fixed length products shall not exceed % of the total delivery. For qb square pipe with theoretical weight greater than kgm, it shall not exceed % of the total delivery. The bending degree of qb square pipe shall not be greater than mm per meter, and the total bending degree shall not be greater than .% of the total length. Galvanized qb square pipe for low-pressure fluid transmission, with standard number of gbt-. Representative materials: QA, qbqb, etc. It is mainly used for conveying water, gas, air, oil and heating hot water or steam,Square tubes for low and medium pressure boilers (gb-) are high-quality carbon structural steel hot-rolled and cold drawn (rolled) square tubes for superheated steam tubes, boiling water tubes for low and medium pressure boilers of various structures and superheated steam tubes, large smoke tubes, small smoke tubes and arch brick tubes for locomotive boilers. Square tubes for high-pressure boilers (gb- is a high-quality carbon steel, alloy steel and stainless heat-resistant steel square tube for the heating surface of water tube boilers with high pressure and above. High pressure square tube for chemical fertilizer equipment (GB - is a high-quality carbon structural steel and alloy steel square tube suitable for chemical equipment and pipelines with working temperature of - ~ ℃ and working pressure of ~ mA.Hundreds of degrees Celsius, which can save energy.QB square tube is a product appeared in recent years, which mainly has strict tolerance and roughness for the dimensions of inner hole and outer wall. Production process classification of large-diameter qb square tube large-diameter qb square tube is divided into hot-rolled seamless square tube, cold drawn seamless square tube, seamless square tube and qb square tube according to production process. Among them,Mocha25 galvanized pipe, qb square tube is divided into: (a) by process & mdash& mdash; Arc welded square pipe, resistance welded square pipe (high frequency and low frequency) gas welded square pipe and furnace welded square pipe (b) are divided by weld & mdash& mdash; Material classification of straight seam welded square pipe and spiral welded square pipe large diameter qb square pipe: plain carbon steel square pipe and low alloy square pipe. Ordinary carbon steel is divided into Q Q q SS, # steel, # steel, etc; Low alloy steels are divided into q Mn, Q, etc.

For transportation: water supply, drainage, sewage treatment engineering, mud transportation, marine water transportation.Pursuit of excellence,Cold drawn or cold rolled precision square tube (gb-) is a cold drawn or cold rolled precision square tube with high dimensional accuracy and good surface finish for mechanical structure and hydraulic equipment. The selection of precision square mechanical structure or hydraulic equipment can greatly save machining hours, improve material rate and improve product quality.At the same time, hanging heating shall be carried out during heating to reduce quenching deformation. For high-precision guide rail, gas nitriding or ion nitriding shall be carried out to reduce deformation; Square tubes have outstanding performance in all aspects of performance. We will also test them in this regard when making square tubes more durable. What outstanding performance do square tubes have in mechanical properties? Next I'll introduce it to you.So flat, and the size and thickness are not standardized, it can reflect that this square tube is a poor product& rdquo;Mocha,Fake and shoddy square tubes are easy to scratch, because the equipment of fake and shoddy material manufacturers is simple and easy to produce burrs and scratch the surface of square tubes. Deep scratches reduce the strength of square tubes.Square tube has a wide range of application fields. Its main field is the construction industry, which promotes the development of economic construction. Because the production process of square tube hole is different, the production design of square tube hole is also different. Next, I will introduce in detail the types of tube hole design below.Functional index analysis of qb square tube - angular plasticity refers to the power of plastic deformation (permanent deformation) without destruction of qb square tube data under load.
