A stainless steel screw-in flange (also known as a threaded flange) is designed to be screwed onto pipes with matching threads rather than welded. This type of flange offers a simple, secure, and reusable connection in various piping systems.

Product Applications for Stainless Screw-In Flange
-
Plumbing Systems
Purpose: Stainless screw-in flanges are used in plumbing systems to connect threaded pipes, valves, and fittings.
Reason: The flange’s threaded connection makes it easy to install or remove components without welding, and stainless steel prevents corrosion in wet or damp environments.
Benefit: Provides a durable, leak-proof seal and is particularly useful in residential, commercial, and industrial plumbing for handling water, steam, or gas.
-
Oil and Gas Pipelines
Purpose: Used in oil and gas pipelines where flanged connections are necessary for sections that need frequent maintenance or replacement.
Reason: Stainless steel offers resistance to high pressure, high temperatures, and corrosion from crude oil and natural gas.
Benefit: Ensures a secure connection while allowing for easy disassembly and reassembly in areas that require frequent inspection or maintenance.
-
HVAC Systems (Heating, Ventilation, and Air Conditioning)
Purpose: Employed in HVAC systems to connect threaded ducting and piping components.
Reason: Stainless steel screw-in flanges are chosen for their ability to handle fluctuating temperatures and resist rust or corrosion in systems carrying air, refrigerants, or water.
Benefit: Provides a reliable, long-lasting connection in systems exposed to different environmental conditions, while allowing for flexibility in assembly and modification.
