brief introduction
The big and small heads whose center is in a straight line are
called concentric big and small heads. The commonly used forming
process is reduced diameter pressing, expanded diameter pressing or
reduced diameter plus expanded diameter pressing. Stamping can also
be used for reducing pipes of some specifications.
distribution characteristics
(1) The bending moment caused by the area pressure difference between the large and small ends of concentric reducer under the action of internal pressure causes the relative opening of the large end and the relative contraction of the small end;
(2) Under the action of internal pressure, the circumferential stress on the inner surface of the large end on the eccentric side and the outer surface of the middle part on the eccentric side of the eccentric reducer is the largest.
Corrosion resistance
316L is widely used in the chemical industry because of its excellent corrosion resistance. 316L is also a derivative steel of 18-8 austenitic stainless steel, with 2 ~ 3% Mo added. On the basis of 316L, many steel grades are also derived. For example, 316Ti is derived after adding a small amount of Ti, 316N is derived after adding a small amount of N, and 317L is derived by increasing the content of Ni and mo.
Most of the existing 316L on the market are produced according to American standards. In consideration of cost, steel mills generally limit the Ni content of products to the lower limit as far as possible. The American standard stipulates that the Ni content of 316L is 10 ~ 14%, and the Japanese standard stipulates that the Ni content of 316L is 12 ~ 15%. According to the minimum standard, there is a difference of 2% in Ni content between American Standard and Japanese standard, which is reflected in the price. Therefore, when purchasing 316L products, customers still need to see whether the products refer to ASTM or JIS standards.
The Mo content of 316L makes the steel have excellent corrosion resistance and can be safely applied to the environment containing halogen ions such as Cl -. Since 316L is mainly used for its chemical properties, steel mills have slightly lower requirements for surface inspection of 316L (compared with 304), and customers with higher surface requirements should strengthen surface inspection.
