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 173-D Single Swivel Socket Introduction
Carbon Steel A36 Galvanized Single Swivel Socket is a heavy-duty key clamp pipe fitting made of A36 carbon steel. It adopts combined electroplating and hot-dip galvanizing surface treatment with 80μm zinc coating thickness, delivering excellent anti-corrosion and rust-proof performance for long-term outdoor and humid environment service.
This fitting features a single swivel joint design, enabling flexible angular adjustment between two connected steel pipes.
Equipped with set screws, it can firmly lock round pipes without welding or complicated cutting. The cast structure provides high mechanical strength and load-bearing capacity. The inner cavity is precisely sized for tight pipe fitting, and the galvanized surface prevents oxidation and abrasion.
Widely used for handrail, guardrail, scaffolding, safety barrier and frame construction. It allows quick assembly and on-site
angle adjustment, simplifying installation and modification of tubular structures. Suitable for industrial, municipal,
architectural and playground framework projects.

Carbon Steel A36 Galvanized 173-D Single Swivel Socket Product Processing
1.Raw Material Inspection & Casting Mould Preparation
Select A36 carbon steel as raw material. Conduct strict incoming inspection to check chemical composition, mechanical properties and material internal quality, reject raw materials with cracks, inclusions and defects. Manufacture casting moulds according to the product dimension drawing. Complete mould cleaning and pre-treatment to guarantee the integrity of cast blanks for single swivel socket.
2.Investment Casting Forming
3.Deburring, Machining & Assembly
4.Pre-galvanizing Surface Pretreatment
5.Composite Electroplating & Hot-dip Galvanizing
6.Final Inspection & Packaging
2.Investment Casting Forming
Melt qualified A36 carbon steel and pour into the pre-treated mould cavity to form integrated cast blanks including two pipe sockets and hinged swivel joint structure. Control pouring temperature and cooling speed to avoid shrinkage holes, air bubbles and deformation. Ensure the cast blank has compact internal structure and complete outline of hinge lugs and pipe holders.
3.Deburring, Machining & Assembly
Remove casting gates, flash and sharp burrs on the blank surface. Perform machining on inner pipe holes, set screw threaded holes and hinge pin holes. Press-fit hinge pin for the swivel part to achieve flexible rotation. Install set screws, test the rotating function to ensure smooth angle adjustment without jamming.
4.Pre-galvanizing Surface Pretreatment
Carry out multi-step pretreatment including degreasing, pickling and activation. Remove oil, rust and oxide scale on the casting surface. Fully rinse and dry the workpiece to obtain clean and active metal surface, which ensures good adhesion of the subsequent composite zinc coating.
5.Composite Electroplating & Hot-dip Galvanizing
Implement combined electroplating and hot-dip galvanizing process to reach 80μm zinc layer thickness. Electroplating forms a uniform base zinc layer covering the complex hinge and threaded areas. Hot-dip galvanizing builds thick protective coating to enhance corrosion resistance. Clean excess zinc residues after galvanizing.
6.Final Inspection & Packaging
Carry out full final inspection, including zinc coating thickness test, dimension check, rotation flexibility test and appearance inspection. Mark qualified products with material grade and specification. Pack finished fittings with protective packing materials to prevent scratch and damage during transportation and storage.
