Yanshan County Bo Yan Pipe Co., Ltd. is located in Yanshan County Industrial Development Zone. North of Beijing and Tianjin and Beijing-Shanghai railway to the east Bohai Sea, Tianjin Port, State Road across the county superior geographical conditions, abundant local resources, for my company's development has laid a good foundation. Best-selling products, and exported to South Korea, Vietnam, carbon steel pipe cap head, Singapore, Malaysia and other countries. I used to pursue "science and technology first, gaining the upper hand, quality, customer supreme, credit first" business ideas, is willing to domestic and foreign users and sincere welcome customers to work together to create a better future. Pipe caps, tube caps head, other names: head, plug, hijab, tube cover, bulkhead. Uses: welded pipe end or mounted on the pipe end male thread to cover plugging the pipe fitting. For closing the pipeline, the role of the same plugs. Cap includes a convex caps, cone shell, adjustable segment, flat lid and tighten port design. Convex cap comprising: a hemispherical cap, oval pipe cap, disc and ball cap crown cap. From the perspective of the force gradually bad convex caps from the hemispherical cap, but the difficulty of making point of view, good manufacturing gradually. Cap parameters: stainless steel, pipe cap head, alloy steel, carbon steel Diameter:. DN15-DN1200 thickness: SCH5-SCH160 standard: ASME DIN JIS BS GB / T JB SH HG, as follows: GB / T12459, GB / T13401, ASME B16.9, head cap manufacturers, SH3408, SH3409, HG / T21635, DL / T695, SY / T0510, DIN2617 uses: water, soft drinks, beer, food, petrochemical, nuclear power, machinery, medical equipment , fertilizer, shipbuilding, water treatment, pipeline and other Weightlessness head swaying uncontrollable elliptical head design time, because it is round so when we designed its search for accurate focus and avoid head due to weightlessness adverse consequences , but some manufacturers of products in the head during normal operation or will appear weightlessness, leading to the project can not function properly, resulting in serious consequences. Elliptical head instability consequences and impact of the head buckling pressure has a great influence through a series of amendments to simplify and experiments can guide cone shells have elastic critical buckling pressure outside the formula 2-6-2 Pressure stability of conical head, checking principle to a series of equations of conical shell under external pressure when the general solution of its instability lists virtually impossible, Niordson shown using the energy obtained by the theory in 1947 Article simply supported at both ends. Head weight loss for many reasons, such as welding problem if head is made of carbon steel or low alloy steel, and then when it is immersed in a solution of hot-dip galvanized or aluminized, it may crack, which is hot dip galvanized aluminized crack, according to head professional analysis, which is processed by the welding residual stress and residual stress common cause, so before that, we should be heat-treated to remove the welding residual stress and processing residual stress, to prevent the occurrence of this phenomenon.
