China Glass Lined Flange Cover

China Glass lined flange cover is a commonly used sealing accessory in chemical equipment,widely used for pipe sealing of glass lined containers,reaction vessels and other equipment.Attention should be paid to the following during installation:
一、Preliminary preparation
Ensure that the glass lined flange cover matches the flange of the equipment in terms of specifications,materials,etc.,and check whether there is any damage or defect on the flange cover and flange surface,especially whether the glass lined layer is intact.If there is any damage,it should be repaired or replaced in a timely manner.Prepare the necessary installation tools,such as bolts,nuts,washers,wrenches,etc.,and ensure that these tools are clean and undamaged to avoid damage to the enamel layer during installation.
二、Installation steps and precautions
1.Cleaning the flange surface:Before installation,the flange surface should be thoroughly cleaned to remove oil stains,dust,and other impurities,ensuring that the flange surface is clean and flat to improve sealing performance.
2.Place gasket:Select the appropriate gasket material based on the medium and temperature,and place it correctly on the flange surface.The gasket should be flat and free of defects to ensure the sealing effect.
3.Align the flange:Align the China glass lined flange cover with the flange of the equipment to ensure that the flange holes are aligned.During the docking process,it is necessary to avoid using tools such as pry bars and hammers to directly contact and collide with the enamel glass parts,in order to avoid damaging the enamel glass layer.
4.Uniform tightening of bolts:Use tools such as wrenches to evenly and gradually tighten bolts and nuts.The installation principle of chemical containers should be followed,which requires symmetrical and uniform gradual tightening to avoid damage to the enamel surface due to excessive local stress.During the tightening process,attention should be paid to checking the tightness of bolts and nuts to ensure that the specified torque requirements are met.
三、Post inspection and maintenance
After installation,the sealing of the enamel glass flange cover should be checked.Leakage can be detected through methods such as pressure testing,and any leaks should be promptly addressed.Regularly inspect and maintain the enamel flange cover,including checking the tightening of bolts and nuts,the sealing performance of gaskets,and the integrity of the enamel layer.If any abnormalities are found,they should be dealt with in a timely manner to ensure the long-term stable operation of the equipment.
In summary,it is necessary to pay attention to the preparation,installation steps and precautions,as well as later inspection and maintenance when installing China glass lined flange covers.Only by strictly following the operating procedures for installation and maintenance can the normal operation and production safety of the equipment be ensured.
