HEMSUN ENGG. INDUSTRIES manufactures PTFE balls in India and exports to Saudi Arabia, shipping to King Abdulaziz Port Dammam, Jubail and Yanbu. We supply solid PTFE spheres from 5 mm to 310 mm in virgin and filled grades for the Kingdom’s petrochemical, refining and oilfield sectors.
Why buyers in Saudi Arabia (Dammam, Jubail, Yanbu, Riyadh) source PTFE balls from HEMSUN
Saudi Arabia operates some of the world’s largest integrated petrochemical complexes at Jubail and Yanbu, and the scale of that infrastructure produces continuous demand for check and seat elements in sampling, additive injection, chemical dosing and analyser circuits. Duty conditions are demanding — high temperature, sour service, and aggressive process chemistry — and specifications are correspondingly strict, with buyers typically requiring documented material grade rather than an unspecified PTFE. Large-diameter spheres for valve overhaul are also in demand and are difficult to source, since few manufacturers can produce void-free PTFE above 150 mm.

Quality Assurance, Testing Protocols & Traceability
- Dimensional CMM Profilometry: Critical diameters, concentricity, and sphericity are verified on coordinate measuring machines against drawing nominals.
- Dielectric Breakdown Voltage Testing: High-voltage spark testing screens moulded parts for micro-voids, pinholes, and internal conductive inclusions before dispatch.
- Specific Gravity & Density Verification: Water displacement density checks according to ASTM D792 ensure full preform compaction and complete oven gel sintering.
- Certificate of Compliance & MTR: Every dispatch includes mill test certificates confirming raw resin lot traceability, filler content, and tensile/elongation values.
Installation, Machining & Maintenance Recommendations
- Tooling Geometry for Machining: Use polished tungsten carbide (C2 grade) or polycrystalline diamond (PCD) inserts with high positive top rake angles (15° to 25°) and sharp cutting edges to prevent material smearing.
- Feed & Speed Rates: High spindle speeds (200 to 450 m/min) combined with moderate feed rates (0.05 to 0.15 mm/rev) ensure mirror surface finishes without localized frictional heating.
- Coolant Application: Water-soluble synthetic coolants or clean air blast prevent thermal expansion during high-speed CNC turning and milling passes.
