Forged Stainless Steel Slip On Flange

The connection of SO flange steel structure conforms to the principle of reliable, clear force transmission, simple structure, convenient manufacturing and saving materials. The joint shall have sufficient strength and sufficient air direction suitable for the execution of the joint means. The connection method of the system structure can be divided into weld connection, rivet connection and bolt connection. Weld joint is the main joint of modern structure. Its advantages of simple structure, any form of components can be directly connected; Material economy, does not weaken the section, production and processing is convenient, can realize automatic operation, the connection is closed well, the structural stiffness of its disadvantage is in the weld near the heat-affected zone, the material of the whole phase of the change, resulting in the change of material, residual stress and residual deformation of the compressive member bearing capacity is reduced to crack structure, with crack day love, it is easy to expand to the whole, The problem of low temperature cold cell is more prominent. Because of the complex structure and the cost of steel and labor, rivets are seldom used now. But the foot nail connection type and system is better, the force transfer is called by, the care is easy to check, in some heavy and directly bear the dynamic load structure, sometimes still used. Zheng bolt connection Zheng bolt connection Kennedy bolt connection and degree bolt connection two kinds of general bolts are divided into, grade. Next and grade is bonded bolt, grade is leased bolt grade Bolt material energy grade is Grade or Grade. The number before the decimal point indicates that the tensile strength of the finished bolt is not less than; the number after the decimal point and the decimal point indicates that the cage strength ratio of the compulsory service point to the tensile strength ratio is or the material energy of the collar and grade bolt is slow; the tensile strength is not less than; the term strength ratio is.

Bolts are rolled from raw mesh. Because the bolt is rough, SO flanges are made of class II holes that were punched last time in a single part or drilled into the design aperture with a drill die. See the diameter of the bolt bolt for details. For the connection with the level bolt, due to the gap between the bolt rod and the bolt hole, by the action of brave force, there will be more yong shear slip, the deformation of the connection, but convenient installation, and can transfer the tension, so it can be used in the connection along the bolt shaft tension. And the shear connection of the secondary structure or the temporary fixed grade bonding bolts for installation are made of the blank after cutting and bonding on the lathe. Smooth, the size is good, screw diameter and bolt aperture is the same, the hole quality requirements are high. Because of its high accuracy, it can be received well. But production and installation complex, high, has rarely used in steel structure. Which rod nominal diameter: Out: There are two types of bolt connection: one is to transfer the force according to the friction positive force, and the shear force does not exceed the friction of the contact surface as the design is called friction connection, the other is to allow the contact surface slip, to reach the limit bearing capacity of the connection as the design criteria, called the pressure type connection bolt is made of steel, steel and steel processing, after heat treatment, The tensile strength of bolts should be no less than and respectively, that is, the energy of the former is grade, and the energy of the other is grade. The aperture of the friction type connection bolt is smaller than the nominal diameter of the bolt. The aperture of the flange bearing type connection bolt is smaller than the nominal diameter of the bolt. The friction type connection of the SO flange bearing type connection bolt has small shear deformation, good elastic energy, simple construction, detachable, fatigue, and is not suitable for the structure bearing dynamic load.
