Carbon wing head of Zhangjiakou butterfly head. Hotels in Kunming head plant

Supply of carbon steel butterfly head Zhangjiakou butterfly head Kunming head plant Hebei Cangzhou Yanshan head plants, has passed the national A3 grade pressure vessel quality system certification. The company is located in the China production base in Yanshan County Head Puwa industrial zone, is specialized in the production and processing head of the manufacturers. I am the owner of a pin head wider use of (nuclear thermal power · Wind power · · Hydropower · Petrochemical · Ship Food pharmaceuticals and paper and printing Sewage treatment) and the like; and by the praise of our customers! The main production company are: oval head, spherical head, cone head, bow head, the ball crown-shaped head, according to clients' special custom-made drawings and samples! (Head diameter 15mm-12 meters). We continue to provide production technology, in the production process continue to strengthen and improve the product quality assurance system, the production process every step of strict control, for each product produced rigorous quality testing, to ensure the quality of products, customers do not return record sales. Companies adhering to the (quality first, the credibility of the first, supply and demand development, cooperation and win-win) in philosophy and sincerely look forward to our customers! Mortar tank Head biggest film stress occurs at the large end. Cone and cylindrical portion junction, due to the geometric discontinuity, the radius of curvature mutation, so where will have a greater lateral thrust, causing the larger edge stress, prone to bending, so be strengthened. Cylinder head for the big end, axial bending stress as the main controlling factor, and is owned by secondary stress, so the stress intensity control, including; stress situation due to the small end of the cylinder is connected at the main average circumferential tensile stress and mean radial compressive stress, it is a local film stress. Large head so stress intensity can be controlled, including, but because of the local film stress distribution here may be beyond the range of the edge effect, for safety reasons, to take the stress intensity control within. For big-endian, section thickness strengthen any case shall not be less than the small-diameter head cone shell thickness is connected, strengthening length should not be less than the cylindrical segment length should not be less than strengthen. Under any circumstances to strengthen the small end segment thickness not less than the thickness of the shell is connected to the cone, cone shell length should not be less than strengthen, the cylindrical segment length should not be less than strengthen. Head punching, drilling, bending and precise line head off other deep-processing. Some have a master's degree head, aviation forgings, hardware tools, forging products; stamping parts, sheet metal parts, drawing parts, bent parts, hydraulic parts, metal hardware products. Spinning Head the blank forming process is a continuous accumulation of local plastic molded into advanced forming process hollow rotating member. Spinning basic way, metal spinning process, can spin test, force and energy parameters of calculation and spinning equipment profile, and other content. Main: elliptical head, spinning head, stainless steel head, pressure vessel head, butterfly head, pipe caps, ball-type head, flat sealing butterfly head Hebei professional production, quality and quantity. Butterfly head what factors determine stability. First, the larger the surface torispherical headed radius, the smaller the radius depth hemming head of the molding on the more favorable light, local high stress spherical sector coupled with the transition area at delineate torispherical Heading surface sector generally not more than the radius of the cylinder diameter, and under no circumstances hemming radius of not less than 10% of the cylinder diameter, and shall not be less than three times the head theoretical wall thickness. In the same force as the premise of the butterfly head with stress discontinuity than the thickness of the butterfly head oval head under the same premise of the wall thickness to be bigger. Butterfly head consists of a sphere, a cylinder of a straight edge height and radius of curvature of the connection of these two parts is less than the radius of the spherical part of the composition of the transition. Dished head as a continuous surface, at the junction of three parts, the radius of curvature of the warp mutations, due to changes in the curvature, and thus there is a bending stress. So there is no wide oval head applications. Butterfly head and cylinder flange connection is available, it can also be soldered connection. Butterfly head connection should be used when welding butt welds. If the thickness of the head and cylinder are different, thicker side shall cut a department, stainless steel is a full scale production manufacturing metal shapes and sizes, and there are many special appearance. Bending stress and tensile stress superposition result, the stress this part protruding from the rest. Compared with the oval-shaped head, not as good as their uniform stress distribution, but the processing than likely, therefore use in engineering is not ideal. But when the oval-shaped head of the mold is difficult, then replaced with a dished head. Implementation of the standards: GB / T25198-2010.
