What are the precautions for flange installation?
Before installation, check the flange specifications, model, and appearance, and clean the connection parts. The appropriate specifications should be selected for bolt tightening, and the bolts should be tightened diagonally according to the specified torque to avoid loose sealing or flange deformation. The installation of sealing gaskets should select the correct size, place them accurately, and pay attention to the winding direction and compression amount of special gaskets. Ensure that the pipeline aligns with the centerline of the flange during installation, check for levelness and perpendicularity to prevent additional stress.

How to maintain flanges and extend their service life?
Regularly inspect the appearance for leaks, deformations, and corrosion, check the tightening status of bolts, and use non-destructive testing technology to detect internal defects in important flange parts. Keep the surface clean and regularly clean the pipeline system that transports easily scaling media. Metal flanges undergo regular anti-corrosion treatment in humid and corrosive environments, such as painting with anti rust paint, galvanizing, etc. Once damage is found, it should be repaired or replaced in a timely manner to ensure that the quality of the repaired and replaced flanges meets the requirements.

How to ensure the sealing performance of flanges?
The carefully designed sealing surface and high-quality sealing gasket work closely together to form a sealing structure. When installing, the sealing gasket should be selected according to the working conditions, ensuring that the gasket size matches the flange sealing surface, accurately placing the gasket, and avoiding deviation or distortion. When tightening bolts, use diagonal sequential tightening method and operate according to the specified torque to ensure that the flange is evenly stressed, so that the sealing surface and gasket are fully fitted, effectively preventing fluid leakage.

What is the process of customizing flanges?
The customer requests special specifications, dimensions, material combinations, design requirements, etc. The manufacturer's professional team evaluates feasibility and communicates with the customer to determine the details of the solution, including drawing drawings, clarifying technical parameters, etc. Afterwards, the manufacturer arranges production, strictly controls quality during the production process, conducts inspections after completion, delivers qualified products to customers, and may provide after-sales technical support after delivery to ensure that customized flanges meet actual usage needs.
