Lap Joint Stub End
Lap Joint Stub Eed is one kind of steel butt-welding pipe fittings, usually used with loose set flange, used in pipeline system to realize flange connection, widely used in petroleum, chemical, natural gas and other industries in the pipeline system, especially in the need for frequent dismantling and maintenance occasions.
Overview
Material: steel material, stainless steel material, rubber material.
Application: Provide good sealing performance, suitable for a variety of media environment, such as petroleum, chemical, gas, pharmaceutical and other fields.
Features:
Excellent sealing performance: The flap design of the flap short section forms a smooth sealing surface, which effectively improves the sealing performance of the connection and reduces the risk of leakage.
Corrosion resistance: usually made of high-grade materials such as stainless steel, with excellent corrosion resistance.
Flexible installation: easy and quick installation and disassembly process, improve construction efficiency.
Adaptability to working conditions: Can be customized according to different pipe sizes and pressure levels, suitable for a wide range of working environments.
Economy and environmental protection: reduce material waste, lower production costs, and reduce environmental pollution.
High reliability: high strength and durability enhance the reliability of the loose flange connection, even under vibration or shock environment, it can still maintain a stable connection state.
