Products Description
A36 Introduction
ASTM A36 is the most commonly used mild and hot-rolled steel. It has excellent welding properties and is suitable for grinding, punching, tapping, drilling and machining processes. Yield strength of ASTM A36 is less than that of cold roll C1018, thus enabling ASTM A36 to bend more readily than C1018. Normally, larger diameters in ASTM A36 are not produced since C1018 hot roll rounds are used.
Carbon Steel A36 Galvanized Swivel Flange Introduction
Carbon Steel A36 Galvanized Swivel Flange is a cast key clamp pipe fitting manufactured from A36 carbon steel. It adopts composite electro-galvanizing and hot-dip galvanizing surface treatment, with a total zinc coating thickness of 80μm. The dual zinc coating structure delivers outstanding rust-proof and anti-corrosion performance, effectively protecting the carbon steel substrate from oxidation, moisture and atmospheric corrosion, and supporting long-term service in outdoor and humid environments.
This swivel flange fitting features a cast tubular socket for inserting round pipes, connected with a base mounting plate through a hinged swivel joint. The swivel design allows adjustable angular rotation between the pipe socket and the base plate. Threaded bosses are reserved on the pipe socket, matched with hex socket set screws. Tightening the set screws can firmly lock the inserted round pipe, realizing fast non-weld assembly. The base plate is pre-machined with mounting holes for secure fixing onto walls, frames or other supporting structures. Product specification marks are cast on the fitting surface for easy identification.
Made of A36 carbon steel, this swivel flange has excellent mechanical strength and load-bearing capacity. It is widely used for modular handrails, safety guardrails, stair railings, stage frames, equipment support frames and other structural assembly projects. It serves as a flexible and reliable pipe connection component for adjustable frame construction.

Carbon Steel A36 Galvanized Swivel Flange Product Processing
1.Raw Material Inspection & Mold Preparation
Select A36 carbon steel as the casting raw material. Strict incoming material inspection is carried out to test chemical composition, tensile strength and yield strength. Raw materials with excessive impurities, slag inclusions and internal defects will be rejected. Fabricate casting molds engraved with product specification marks. Complete mold preheating and release agent coating treatment to guarantee sharp casting profile, clear marking and smooth surface for the swivel flange blank.
2.Casting & Forming
3.Deburring, Shot Blasting & Machining
4.Surface Pretreatment
5.Composite Electro-galvanizing & Hot-dip Galvanizing
6.Final Inspection & Packaging
2.Casting & Forming
Melt qualified A36 carbon steel under precisely controlled temperature. Pour molten steel into the pre-treated mold cavity to form integrated cast blanks, including pipe socket, hinged swivel joint and rectangular base plate with mounting hole pre-position. Regulate pouring speed and cooling rate to avoid shrinkage cavities, pores and deformation. Ensure the blank has compact internal structure, uniform wall thickness and complete contour of hinge lugs and base plate.
3.Deburring, Shot Blasting & Machining
Remove casting gates, risers, flash and sharp burrs by grinding. Conduct shot blasting to clear surface sand residue and oxide scale. Perform precision machining on threaded bosses and tap internal threads for hex socket set screws. Drill and ream fixing holes on the base plate, finish hinge pin holes to match the pin assembly requirement. Verify inner diameter of pipe socket to meet tolerance for round pipe insertion.
4.Surface Pretreatment
Implement multi-stage pretreatment including degreasing, pickling and activation. Fully remove oil stains, rust and oxide layers on the casting surface. Rinse and dry the workpiece thoroughly to achieve a clean and active substrate surface, which can greatly improve the adhesion of subsequent composite zinc coating.
5.Composite Electro-galvanizing & Hot-dip Galvanizing
Adopt combined electro-galvanizing and hot-dip galvanizing processes to form composite anti-corrosion zinc layer with total thickness up to 80μm. Electro-galvanizing provides a thin, uniform base zinc layer covering complex hinge and threaded areas. Hot-dip galvanizing builds up thick protective coating, enhancing overall anti-rust and corrosion resistance, suitable for outdoor and humid working environments.
6.Final Inspection & Packaging
Carry out comprehensive quality inspection, including zinc coating thickness test, dimensional tolerance check, thread fit test, hinge rotation flexibility test and surface visual inspection. Label qualified swivel flange fittings with material grade, specification and batch number. Pack finished products with anti-scratch protective packaging to prevent surface damage during storage and transportation.
