Elbow manufacturer's technical analysis of products
Elbow manufacturers mainly according to the customer request production all sorts of different type and material of elbow pipe fittings, elbow pipe fittings categories include: carbon steel elbow, seamless elbow, straight seam pipe bend, welding elbow, butt welding elbow, right-angle bend, bend 45 degrees, 90 degrees bend, 180 degree Angle, and customer ordering a variety of different angles of bend pipe fittings. All customers who order elbow pipe fittings in our company will be sent to the designated place within the time customers need, and provide customers with quality assurance elbow pipe products at low prices.
Our company makes a detailed analysis of the technical requirements of elbow pipe fittings: Since most pipe fittings are used for welding, in order to improve the welding quality, the end parts are beveled, with a certain Angle and a certain edge. This requirement is also strict, and the thickness of the edge, the Angle and the range of deviation are specified. The surface quality and mechanical properties are basically the same as pipes. For the convenience of welding, the pipe fittings are of the same steel grade as the pipe to be connected.
That is, all pipe fittings should be surface treated, and the oxide iron on the inner and outer surfaces should be sprayed off by shot peening, and then coated with anti-corrosion paint. This is for export needs, moreover, in all parts of the world is also to facilitate transportation to prevent corrosion and oxidation, to do this work.
It is to the requirement of packaging for small pipe fittings, such as export, need to do wooden cases, about 1 cubic meter, the number of elbow in the box can not exceed about a ton, the standard allows suit, that is, a large set of small, but the total weight generally can not exceed 1 ton. For large pieces y needs to be packed individually, like 24 "must be packed individually. Another is the packaging mark, the mark is to indicate the size, steel number, batch number, manufacturer's mark and so on.
Elbow manufacturers of the product manufacturing standards are: gb, electrical, water, American standard, German standard, Japanese standard, etc. According to the radius of curvature, it can be divided into long radius elbow and short radius elbow. Long radius elbow refers to the outer diameter of the pipe whose radius of curvature is equal to 1.5 times, that is, R=1.5D. Short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R= 1.0d. (D is elbow diameter, R is radius of curvature). According to the pressure grade, there are about 17 kinds of tubes, which are the same as American standards, including Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, SCH100, Sch120, Sch140, Sch160, XXS STD and XS are commonly used.
