1. Work environment
Medium characteristics: Analyze the chemical properties of the conveying medium, such as whether it is corrosive. If the medium is highly corrosive, lead bronze flanges will be a suitable choice due to their good corrosion resistance .
Consider the temperature and pressure of the medium : Different lead bronze flanges may have different applicable temperature and pressure ranges. Make sure the selected flange can operate safely and reliably at the operating temperature and pressure.
Workplace: If the workplace is in a corrosive environment such as humidity, ocean, etc., the corrosion resistance of the lead bronze flange can play an important role. Consider the vibration and shock conditions in the workplace. Choose a lead bronze flange with sufficient strength and toughness to withstand possible vibration and shock.
2. Size requirements
Pipe diameter and pressure rating: According to the diameter and design pressure of the pipeline, select the corresponding specification of lead bronze flange. Make sure the size of the flange matches the pipeline and can withstand the required pressure.
Pay attention to the pressure rating mark of the flange and select a flange that meets the working pressure requirements. Flanges of different pressure ratings may differ in structure and thickness.
Connection method: Determine the connection method of the piping system, such as bolt connection, welding, etc. Select the corresponding lead bronze flange type.
Consider the sealing surface form of the flange, such as flat surface, convex surface, concave surface, etc. Select the appropriate sealing surface form according to different sealing requirements and medium characteristics.
3. Quality and Standards
Product quality: Choose lead bronze flanges produced by regular manufacturers to ensure reliable product quality. You can check the manufacturer's qualification certificate, production process and quality control system information.
Check the appearance quality of the flange, such as whether the surface is smooth, free of cracks, pores and other defects. Good appearance quality usually reflects the manufacturing process and quality level of the product.
Standard compliance: Make sure the selected lead bronze flanges comply with relevant national standards, industry standards or international standards. The standards specify the flange size, pressure rating, material requirements, manufacturing process and other aspects. Flanges that meet the standards can guarantee their performance and safety. You can ask the supplier for the product's quality inspection report and certificate of conformity to verify the flange's standard compliance.
