Pipeline Manufacturing Co., Ltd. Hebei billion in gold (www.yijinguanjian.com) is located in Cangzhou City, Hebei Province, Yanshan Puwa Industrial Development Zone, Contact: Alan Li Tong is usually based on the material properties of cold stamping and punching elbow two hot stamping, and the ability to choose the device cold stamping or hot stamping. Before stamping, tube placed on the lower die, the inner core and the end of the tube into the steel stamping die manufacturer elbow, began to suppress the downward movement of the upper die, die by the constraints and supporting role within the outer mold making Elbow forming. Compared with hot push technology, the appearance of the inferior quality of the former stamping; stamping elbow while forming outside the arc in tension, no other parts of the excess metal to compensate, so the wall thickness at the outer arc of about 10% to about thinning . However, as for single-piece production and low cost stamped steel 90 ° elbow, the elbow stamping process used for small quantities, thick-walled elbow manufacturing. First, the environmental protection: PE-RT can be recycled, do not pollute the environment. The PEX can not be recycled will produce secondary pollution; stamping elbow pipe trends: raw material not only has qualified stamping elbow creep broken curve, and its affordable steel stamping elbow pipe suppliers, construction convenient compared to other species, fast, reliable connection among the most standard form of mutual melting stage form of hot melt connection fittings parts of the aperture is larger than the inner diameter of the same size pipe stamping elbow, in the system because there is no local necking mechanical connection, so the system fluid resistance relatively small. Second, the long-term pressure resistance, just in terms of design stress, pressure resistance GB stamping elbow best. However, due to various factors, the actual floor heating pipe wall thickness is typically 2mm. And in the various types of pipe wall thickness can meet the requirements of floor heating, stamping elbow pipe pressure advantages not manifest; Third, the low-temperature thermal shock resistance: PE - RT and low temperature impact properties PEX better. Winter construction pipes susceptible to shock and rupture, increasing the flexibility of the construction arrangements.
