FAQs of Stubend Fitting:
Q: How are Stubend Fittings with Lap Joint Stub Ends typically installed?
A: Stubend Fittings are installed by butt welding the straight end to the pipe, while the flanged (lap joint) end allows a separate backing flange to be fitted for easy assembly or disassembly of the pipe system, enabling flexible and leak-proof connections.
Q: What applications are Stubend Fittings most commonly used for?
A: They are widely used in industrial piping systems, including chemical plants, oil & gas refineries, water treatment facilities, and wherever flanged pipe joints are necessary. Their customizability makes them suitable for both new setups and pipe maintenance projects.
Q: When should I choose a particular pressure rating (150#, 300#, 600#) for these fittings?
A: The pressure rating should match the maximum operating pressure of your piping system. Select 150#, 300#, or 600# based on the applications requirements and client specifications to ensure safety and regulatory compliance.
Q: Where are these Stubend Fittings manufactured and how are they packaged for export?
A: Our Stubend Fittings are manufactured in India, using advanced forging or machining processes. For international or domestic shipping, they are packed in export-worthy wooden cases to ensure product safety and prevent damage during transit.
Q: What is the lead time for Stubend Fittings if I have a custom order?
A: We maintain ready stock for standard sizes, but lead time for customized fittings depends on order specifications. Typically, production and delivery timelines are discussed and confirmed during client consultation to ensure timely project completion.
Q: What benefits do Stubend Fittings offer over other types of pipe fittings?
A: Stubend Fittings provide flexibility by allowing easy disassembly for inspection or replacement, exceptional corrosion and heat resistance, adherence to international standards, and compatibility with a wide range of flanges and piping systems.
Q: How are the dimensions and weight determined for these Stubend Fittings?
A: Dimensions such as length, width, height, and wall thickness are customized as per client requirements or referenced standards. The weight of each fitting varies depending on its size and material grade, which is specified at the time of order.
