Welding is one of the most commonly used connection methods for stainless steel elbows, with advantages such as high connection strength, good sealing, and strong pressure resistance.
characteristic:
High strength: Welding connections can firmly connect elbows and pipelines together, forming a whole that can withstand high pressure and temperature.
Good sealing: Welding connections can achieve complete sealing and prevent leakage, especially suitable for pipeline systems that transport high-pressure, toxic, harmful, or flammable and explosive media.
Wide applicability: Suitable for stainless steel pipes of various specifications and materials, including large-diameter pipes.
Application scenarios:
Industrial sector: such as chemical, petroleum, natural gas and other industries, used for the transportation of high-pressure, high-temperature, corrosive media.
In the field of architecture, such as water supply and drainage systems, hot water supply systems, etc. for high-rise buildings.
Installation precautions:
Before welding, it is necessary to clean the ends of the pipes and bends to remove impurities such as oil and rust, ensuring the quality of the welding.
Strict control of welding parameters (such as current, voltage, welding speed, etc.) is required during the welding process to prevent welding defects.
After welding is completed, non-destructive testing (such as X-ray testing, ultrasonic testing, etc.) is usually required to ensure the quality of the weld seam.
Flange connection is a method of connecting elbows to pipelines through flanges and bolts, which has the characteristics of easy installation and disassembly, good sealing, etc.
characteristic:
Easy installation: Flange connections can be quickly connected and disassembled through bolts, making it convenient for the installation, maintenance, and inspection of pipeline sys
Threaded connection is a method of connecting elbows to pipelines through threads, which has the characteristics of easy installation and reliable connection. However, its sealing and strength are relatively low compared to welded connections.
characteristic:
Easy installation: Threaded connections are achieved through threaded engagement, making installation and disassembly relatively simple.
Limited applicability: usually suitable for small caliber (DN15-DN100) and medium low pressure pipeline systems.
Good sealing performance: A good sealing effect can be achieved through auxiliary materials such as thread sealant or raw tape.
Application scenarios:
Civil buildings: such as water supply and drainage systems, gas pipeline systems for residential and commercial buildings.
Small industrial equipment: such as small boilers, compressed air systems, etc.
tems.
Good sealing performance: Sealing is achieved through flange gaskets (such as asbestos gaskets, rubber gaskets, metal gaskets, etc.), which can effectively prevent leakage.
Wide applicability: Suitable for medium and low pressure pipeline systems, especially for occasions that require frequent disassembly.
Application scenarios:
Chemical industry: pipeline systems used for transporting corrosive media such as acids, alkalis, and salts.
Food processing industry: pipeline systems used for transporting food raw materials, semi-finished products, and finished products.
Pharmaceutical industry: pipeline systems used in the production process of drugs.
Installation precautions:
When connecting flanges, it is necessary to ensure that the sealing surface of the flange is flat, clean, and free of defects such as scratches and dents.
When installing bolts, they should be tightened evenly to avoid seal failure caused by uneven stress.
Choose the appropriate flange gasket and select the appropriate gasket material based on the properties of the medium and working temperature.
Installation precautions:
When connecting threads, it is necessary to wrap raw tape or apply sealant on the threads to ensure sealing.
During installation, excessive tightening should be avoided to avoid damaging the threads.
The threaded pipeline system should be regularly inspected during operation to prevent leakage caused by vibration or temperature changes.
Clamp connection is a method of connecting elbows to pipelines through clamps, which has the advantages of fast installation, good sealing, and high reliability.
characteristic:
Quick installation: The clamp connection fixes the pipeline and elbow together with clamps and bolts, making the installation process simple and fast.
Good sealing performance: Sealing is achieved through rubber sealing rings, which can effectively prevent leakage.
Wide applicability: Suitable for medium and low pressure pipeline systems, especially for occasions that require frequent disassembly and maintenance.
Application scenarios:
Fire protection system: used for fire water supply pipeline system.
HVAC system: used for piping systems such as hot water, cold water, and air conditioning water.
Food processing industry: pipeline systems used for transporting food raw materials and finished products.
Installation precautions:
When connecting clamps, it is necessary to ensure the integrity and cleanliness of the rubber sealing ring to avoid leakage caused by damage or impurities to the sealing ring.
When installing the clamp, the bolts should be tightened evenly to ensure a tight fit between the clamp and the pipeline.
Regularly check the tightness of the clamp connection to prevent leakage caused by looseness.
