Product Description:

SA516Gr.70 belongs to the medium, low temperature pressure vessel with carbon steel, the implementation of ASME standard. In order to satisfy the different requirements of users, convenient for production management, according to S, P steel requirements and divided into I, II, III three levels.

Introduction to SA516GR70  

The spherical tank anti hydrogen sulfur resistant steel plate, domestic production,by the Wuyang steel plant with advanced technology, mature than other steel mills.By using electric furnace steelmaking, scrap metal into pure steel, steel, widely used in wide application in the industry of petroleum, chemical, power station, boiler etc., used for the production of reactor, heat exchanger, separator, spherical tank,oil tank

Wugang 2006 R & D and production (4776 tons 130mm thick SA516Gr70N steel plate, Wugang for the development of Sichuan Puguang gas field productionreplaced the imported products, a strong impetus to the localization of the plateprocess of petrochemical equipment), which is different from the SA516Gr60 lies in that the tensile strength.

Grade: SA515Gr60, SA515Gr70 and American Standard, SA516Gr60, SA516Gr70,SA516Gr60N, SA516Gr70N

Executive standard: USA ASTM, ASME standard

Chemical composition: C = 0.30, Mn:0.79-1.30, P = 0.035, S = 0.035, Si:0.13-0.45.

Q:What is a cold rolled sheet with plastic sprayed?
Among them, plastic spraying is a surface treatment method of spraying plastic powder on parts. Spray is the electrostatic powder we often speak of spraying, it is the use of electrostatic generator to make plastic powder charged, adsorbed on the iron surface, then after 180 to 220 DEG C baking, the powder melting adhesion on the surface of metal, plastic products used for the indoor use of the film is flat or matte effect. Spray powder mainly has acrylic powder, polyester powder and so on.
Q:Stainless steel plate and steel welding
With almost 2.5 of the welding, and certainly not the same as before the color. You can buy acid lotion passivation, and then washed with water, basically with stainless steel, the original color is not much
Q:Should the carbon fiber reinforce the steel bar on the side of the beam?
Not necessarily, mainly depends on how the design is calculated, usually put 100~200mm carbon fiber layering
Q:The difference and usage of color steel sandwich panel and color profiled steel sheet
The wall of the project is made of type 950 rock wool wall sandwich board, and the roof is made of type 960 rock wool roof sandwich board
Q:What do you pay attention to?
Considering the quality factor, quality of the primer must have good corrosion resistance, and the old paint film or metal layer has good adhesion, excellent filling force, smooth surface; from the construction perspective, quality should be applied to the body of the primer, vehicle repair and local repair; from the view of time and operation high quality, primer volatilization and shorter drying time and simple mixed paint; considering body material, quality repair primer should be used for the old paint, aluminum, galvanized steel, stainless steel, fiber, plastic products, hard wood, putty and other substrates.
Q:How to choose welding method for welding different plate and thick steel plate?
For welding efficiency:General welding or argon arc welding of thin plate, medium plate with gas shielded welding (such as two welding), thick plate with submerged arc welding (usually not groove, single-sided, once the penetration of up to 20mm).
Q:How much is one meter for laser cutting steel plates?
The length and width are smaller than 300MM and the thickness is less than 12MM, because of good nesting material, we provide. By weight, the carbon steel is 8~9 yuan per kilogram and the quantity is large, 7~8 yuan per kilogram.
Q:The difference between steel edge sealing strip and steel plate putty water stop belt
The steel sealing strip is made of pure steel plate and can be divided into galvanized steel sheet, ordinary steel plate and stainless steel water stop belt.The steel plate putty water stop belt is covered with butyl rubber. The main material is a kind of rubber and plastic material with good aging resistance. It has a strong self adhesion, and it does not run in summer. Low temperature in winter, no brittle, and has excellent water, acid and alkali resistance and aging resistance, long service life, the product itself non-toxic, good environment. In order to withstand certain bending and pressure. There are 0.4 or 0.6mm steel plates in the center. The steel plate putty water stopping belt can provide reliable waterproof and anti-seepage function to the building joint. Steel plate putty water stop series products include various specifications and types of products, and can produce various types of steel sheet, putty, water stop belt according to user requirements, to meet the actual needs of the project.
Q:What is the width of carbon steel coil and the width of stainless steel coil, one is 1250 and the other is 1219?
But the technical content of carbon steel with stainless steel is different, our country in more than 10 years ago the ability of continuous rolling of stainless steel is not high, equipment are imported, the stainless steel mill is dominated by 1219-1300, but also the development of national wide stainless steel 1500-2050, but the price is expensive at least thousands of dollars a ton, after all put the equipment to recover the cost, and the number of business orders is not much, it is difficult to find a spot on the market. Carbon steel countries have developed for many years, technology and equipment are mature, so the market has 1250 as production standards.
Q:What is a die steel plate?
Pressure plate template is made of galvanized steel sheet or the antiseptic treatment, the machine rolled into a groove plate with a cross section of the ladder waveform or project template material open box steel shell.
