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 167-D Double Swivel Socket Introduction
Carbon Steel A36 Galvanized Double Swivel Socket is a heavy-duty key clamp pipe fitting manufactured from A36 carbon steel. It adopts combined electroplating and hot-dip galvanizing surface treatment with 80μm zinc coating thickness, offering superior anti-corrosion and rust-proof performance for long-term service in outdoor and humid working environments.
This pipe fitting features double swivel hinge design, enabling independent flexible angle adjustment for two connected steel pipes relative to the central socket. Equipped with set screws on each pipe socket, it can firmly lock round pipes without welding or complicated cutting work. The cast integrated structure delivers high mechanical strength and stable load-bearing capacity. The inner bore is precisely machined to match outer diameter of steel pipes for tight fit, and galvanized surface effectively resists oxidation and abrasion.
It is widely applied for handrails, guardrails, scaffolding, safety barriers and tubular frame construction projects. The double swivel structure allows multi-angle adjustment on site, greatly simplifying assembly and modification of complex pipe frameworks. It is an ideal connection component for architectural, municipal, industrial and playground frame systems.

Carbon Steel A36 Galvanized 167-D Double Swivel Socket Product Processing
1.Raw Material Inspection & Casting Mould Preparation
Select A36 carbon steel as base raw material. Carry out strict incoming material inspection, including chemical composition analysis, mechanical property test and internal defect detection. Reject raw materials with inclusions, cracks and shrinkage defects. Fabricate precision casting moulds according to product engineering drawings, clean mould cavity and apply protective coating. Verify mould dimensional accuracy to ensure complete forming of central socket and dual hinge lug structure for double swivel socket.
2.Investment Casting Forming
3.Deburring, Precision Machining & Hinge Assembly
4.Pre-galvanizing Multi-step Surface Pretreatment
5.Composite Electroplating & Hot-dip Galvanizing
6. Full Final Inspection & Protective Packaging
2.Investment Casting Forming
Melt qualified A36 carbon steel and pour molten steel into the pre-treated mould cavity. Precisely control pouring temperature, flow rate and cooling curve to avoid air holes, shrinkage cavities and structural distortion. Form integrated casting blank consisting of one central pipe socket and two hinged swivel assemblies. After natural cooling, strip the casting and remove the gating system to obtain rough blank with complete double hinge profile.
3.Deburring, Precision Machining & Hinge Assembly
Remove casting flash, gate residues and sharp burrs on the whole blank. Conduct precision machining for inner pipe holes, set screw threaded holes and hinge pin mounting holes. Press-fit hinge pins for both swivel joints, assemble the rotating components. Conduct manual rotation test repeatedly to ensure two swivel ends can rotate independently and smoothly without jamming, wobble or excessive clearance. Install grub screws and check screw fit.
4.Pre-galvanizing Multi-step Surface Pretreatment
Implement multi-stage pretreatment: alkaline degreasing to eliminate surface grease and contaminants; acid pickling to remove rust and oxide scale; water rinsing to avoid residual acid contamination; surface activation treatment to expose pure metal substrate. Fully dry the workpiece to guarantee clean and active metal surface, which strengthens adhesion between base metal and composite zinc coating.
5.Composite Electroplating & Hot-dip Galvanizing
Adopt combined electroplating and hot-dip galvanizing process to reach total zinc coating thickness of 80μm. Electroplating deposits a thin and uniform base zinc layer, covering complex hinge gaps and threaded areas. Then perform hot-dip galvanizing to build thick outer zinc layer for heavy anti-corrosion protection. After galvanizing, remove excess zinc nodules and zinc slag, inspect for coating peeling, bare spots and uneven coverage.
6. Full Final Inspection & Protective Packaging
Carry out comprehensive finished product inspection, including dimensional tolerance check, 80μm zinc layer thickness test, appearance inspection, dual swivel flexibility test and set screw locking performance test. Sort and mark qualified products with specification and batch information. Pack fittings with anti-rust separators, load into cartons or wooden cases to prevent scratches and collision damage during warehouse storage and ocean transportation.
