Product Description

Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. This high alloy stainless
steel is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion. Grade 904L is non-magnetic, and offers excellent formability, toughness and weldability.Grade 904L contains high amounts of expensive ingredients, such as molybdenum and nickel. Today, most of the applications that employ grade 904L are replaced by low-cost duplex stainless steel 2205.

A threaded coupling is a pipe fitting used to connect two pipes with external threads. It achieves the extension, connection, or repair of pipes through the interlocking of internal threads with the external threads of the pipes, and is widely used in pipeline systems such as petroleum, chemical, water supply and drainage, and gas.Core features and functionsConnection function: The core function is to quickly and reliably connect pipes of the same specification with external threads. No welding is required (in some scenarios, sealing glue or tape can be used to enhance sealing performance), and the assembly and disassembly are relatively convenient.Sealing guarantee: The inner wall is usually designed with sealing structures (such as conical pipe thread sealing, flat sealing), or it needs to be combined with sealing materials (sealing tape, thread sealant), to prevent leakage of the medium (liquid, gas) inside the pipe.Specification compatibility: It must be fully matched with the thread specifications of the pipes (such as metric threads, imperial pipe threads, American threads), and the pipe diameter. Common materials include carbon steel, stainless steel, copper, plastic, etc. Selection should be based on the characteristics of the medium (corrosiveness, temperature, pressure).Main application scenariosPipe extension: In the laying of water supply and drainage, gas pipelines, connecting two short pipes to extend the pipeline.Pipe repair: When a part of the pipe is damaged but not severely damaged, the damaged section can be cut off, and the two intact sections of the pipe can be connected with the pipe clamp.Equipment interface: Connecting the pipe to the valve, pump, instrument, etc. with external threads of the equipment interface to achieve system assembly.
