Welcome to Hebei million gold piping _ concentric eccentric reducer [manufacturers] _ reducers supplied by Hebei billion gold piping. We are Hebei billion gold Pipe Manufacturing Co., Ltd. (www.yijinguanjian.com) here: Hebei Cangzhou specializes in: insulation joints, insulating flange, flanges, elbows, head, tee, head, Stone, Steel differences Structural features diameter pipe has many specific performance steel concentric reducer price, such as: ① usually belong shell structure; ② Except concentric reducer, the structure of non-axial symmetry, does not belong to the rotating shell; ③ theory, for Eccentric reducers, cross-section perpendicular to the pipe axis but not the round face everywhere equal wall thickness, with the ends of the tube parallel to the surface (that is, perpendicular to the pipe axis) is a cross-section of a round face but uneven thickness; ④ Reducing Bend tube is a hyperboloid structure; various other fittings ⑤ and Elbow or tee, elbow reducers both end surfaces even with an equal diameter, wall thickness and other relatively straight pick, arch their big end there concave, convex small end of the outer arch exist, adjustable cross-section at the beginning of its structural mutations also exist; ⑥ As the molding process, the tube wall thickness often appear uneven oval cross-section. Diameter pipe Standard: GB British standard and non-standard American Standard high pressure stamping. Quality reducers should be consistent with the current national standard "steel welded seamless pipe fittings" GB / T 12459-2005 and "steel pipe fittings system" provides GB/T13401-2005, the roundness diameter pipe should not exceed corresponding to 1% of the outer diameter side, and the tolerance of ± 3mm. Diameter pipe material execution SY/T5037, GB/T9711, GB/T8163, American Standard ASTM A106/A53 GRB, API 5L, APT5CT, ASTM A105, ASTM A234, ASTM A106, DIN German standards and customer requirements standards. In recent years, mounds with pipe fittings and pipe making rapid economic development, reducers as mounds of competitive enterprises to develop, while the county government also embarked on diameter pipe industry norms for governance, promote from a variety of degree diameter pipe industry associations and the development of the Group. Gold Pipe Manufacturing Co., Ltd. Hebei billion, has been manufacturing pipe fittings constantly forge ahead, to encourage employees to play a positive sense of innovation steel wear-diameter pipe, guide enterprises out of the world market, and vigorously the introduction of foreign advanced technology, enhanced enterprise exchanges and cooperation between the international market, and learn from foreign advanced production and technology, and advanced management concepts diameter pipe, for the domestic and international markets are able to have a broader market. All along, reducers are in constant development and progress, also to promote the development of different industries, occupies an important position in China's economic development, but also help enterprises to improve even more over the edge in a competitive peer companies diameter pipe industry also continues to develop and grow, the industry continued into the different heights up to ensure that one of the industry's highest peak standing. Venture has not stopped long ago, through the tireless efforts of the county and the county government, invited to the China Association for Promoting economic exchanges towns, experts and Research Institute of the Chinese Academy of urban and rural concentric, eccentric reducer manufacturers, China National Hardware Association personnel, in order to mounds of diameter pipe industry to do research, but also to declare the "Hometown of Chinese elbow pipe," People believe mounds, diligent and intelligent mounds definitely put his elbow pipe band as a new era . Diameter pipe in the development of the industry, and continuously improve the ability to resist risks, explore the international sales market, vigorously develop scale enterprises, continuous integration of information resources, form a group of foreign operations business model, full-diameter pipe industry competitive advantage, making mounds of diameter pipe industry gain a firm footing in the competitive world market.
