Precautions for installation of carbon steel flange fittings

Precautions for installation of carbon steel flange fittings

(1) The gasket should have good oil resistance and aging resistance, as well as relatively good elasticity and mechanical strength. For installation, gaskets of different cross-sections and sizes should be selected according to the shape of the joint and placed correctly.

(2) The apron of the carbon steel flange should be placed in the concave-convex groove in any direction and with the big end inward, and the installation must not be distorted. Negligence should be inspected. The molten steel ladle, after verification, is given above the ladle injection port, and the shroud will be injected into the tundish.

(3) The fastening force of the carbon steel flange should be uniform, and the compression of the rubber pad should be controlled at about 1/3.

(4) Different steel structures can match the vibration process of the crystallizer and mold slag, thereby realizing the injection of stainless steel pipe fittings.

(5) The carbon steel flange shall have sufficient strength and shall not be deformed during fastening. The sealing surface of the carbon steel flange should be flat and clean, and the oil and rust spots should be carefully cleaned during installation.

The storage and maintenance of carbon steel flanges are very important. Generally, carbon steel materials are used in projects. The surface of carbon steel flanges is prone to floating rust, and the appearance is unsightly after a long time of storage. The storage of flanges should not be placed directly on the ground. First, put some moisture-proof mats on the ground, and then arrange the flanges neatly. When placing them, leave a channel between the carbon steel flanges and the carbon steel flanges, which can not only play a role in ventilation but also facilitate the carbon steel flanges. Shipping of steel flanges.

The details are as follows:

① Different materials should be stored separately and marked;

②The same material, different types and specifications are stored separately, and corresponding labels are made;

③Stack neatly. Avoid bumping, and pay attention to rust prevention for carbon steel flanges.
