Chiho few points Hebei steel pipe industry standard eccentric head machining should pay attention to: 1, the control caliber: DIN standard (DN10-DN150) by drawing production of carbon steel reducer, 3A / IDF standard (1/2 ' -6 '), ISO standard (Ф12.7-Ф152.4), 2, international industry standards: DIN, ISO, SMS, 3A, IDF, etc. 3. Material: Stainless steel large diameter different 304,316,316L diameter pipe, 4, quality and use: the size of the inside and outside the head with a high-grade polishing equipment, which will reach the surface precision requirements, this product is suitable for dairy, food, beer, beverage steel eccentric reducer sales, pharmaceutical, cosmetics and other industrial fields, 5, external processing: according to user requirements to map, sample processing non-standard products, 6, Connection: Clamp (quick), welded, threaded (union) where Chiho Hebei steel pipe industry Reducing quality management should be consistent with current national standard "diameter welded steel pipe pieces" GB / T 12459-2005, roundness diameter pipe should not exceed 1% of the respective ends of the outer diameter, and the tolerance of ± 3mm ; diameter pipe size tolerances shall comply with Table 4.2.2-3 of. Reducer Executive 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. Reducing the size of the head known as carbon steel pipe diameter pipe, it is divided into concentric and eccentric head size head. Representation is the largest diameter multiplied by the small head diameter, such as '8 × 6' represent the bulk of the diameter of 8 inches, 6 inches in diameter small head size head. Reducing carbon steel pipe forming process is reduced in diameter pipe with a diameter equal to the diameter of the large end of the tube into the forming die, along the axial direction of the tube pressing the metal along the cavity forming motion and contraction. Depending on the size reducer adjustable, divided into one or more press-forming press forming. Reducing carbon steel pipe for a pipeline adjustable pipe at. Forming process commonly used to suppress necking, expanding suppress or necking plus expanding suppress certain specifications diameter pipe may also be stamping. Reducing carbon steel tube production, Hebei Chiho (certified), carbon steel reducer by Chiho Hebei Industry Co., Ltd. Hebei Chiho Pipe Co., Ltd. (www.hbqh628.com) (www.hbqh628.com) Hebei Cangzhou, forging leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer demand.
