ZTT Indonesia Special?Optical?Fiber Capacity Expansion Project｜VTON Complete Solution of Valves & Flow Meters for Overseas Preform & Drawing Production Line

Driven by surging demand for global AI computing network and 5G communication, ZTT launches phase?2 capacity?expansion project for special?optical?fiber plant near Jakarta, Indonesia. New production lines for optical?fiber preform manufacturing, fiber drawing and coating?cabling are built, focusing on G.657 bend?insensitive special fiber and high?speed multimode fiber for North?American and Southeast?Asian customers. The Indonesia?based manufacturing layout optimizes trade?tariff risks. The plant covers six major fluid?system modules: special?gas pipeline for preform VAD/OVD deposition, UPW ultrapure?water system, drawing?tower cooling?water circulation, coating?chemical feeding, process wastewater treatment and plant?wide utility gas?water system. VTON delivers full?set valves and flow?meters fluid?control package for EPC contractor, supporting plant construction and long?term O&M procurement.

Project Challenges

1. VAD/OVD vapor?deposition process for optical preform requires      ultra?stable flow of special process gas and high?purity chemicals. Minor      flow fluctuation will trigger internal defects on preform and reduce yield      of special optical fiber. Organic solvents used in coating process are      corrosive.

2. UPW system demands high?purity piping with zero?leakage and no?precipitation.      Impurity precipitation from valves will contaminate fiber coating layer.

3. Wide?range media including high?purity process gas, glycol      coolant, acid?alkali wastewater and organic solvents. Multiple flow?meter      types are required for large?flow and micro?flow conditions.

4. Indonesian SNI import compliance requires complete documents:      certificate of origin, material spectroscopy reports, CE certificates and      factory inspection reports. Missing paperwork may cause customs detention      and delay expansion schedule.

5. Tropical hot?humid coastal climate with salt?fog corrosion.      Instruments and valves shall support DCS communication. Tight timeline      requires split cross?border shipment, remote commissioning and fast spare?parts      delivery.

VTON Full Delivery Scope (Valves & Flow Meters List)

Flow Meters

1. PTFE?lined electromagnetic flow meters: Measure large?flow rate      for UPW circulation and acid?alkali wastewater; 4?20?mA / Modbus?RTU output for DCS integration.

2. Hastelloy metal?tube rotameters: Precise micro?flow measurement      & control for coating organic solvents and trace chemical dosing for      fiber?coating process.

3. Thermal gas mass flow meters: Measure protective gas such as      nitrogen and argon in preform workshop, to stabilize gas?mixing ratio for      vapor?deposition process.

4. Turbine flow meters: Monitor glycol cooling?water loop flow for      fiber?drawing towers, track heat?dissipation status of drawing equipment.

Valves

1. Pneumatic control valves with Hastelloy trim: Precise pressure      & flow regulation for chemical and special?gas pipelines, compatible      with corrosive media for preform production and fiber coating.

2. PTFE?lined ball valves & PTFE?lined diaphragm valves: On?off      for UPW and organic?solvent pipelines, high?purity non?precipitation      design to avoid secondary medium contamination.

3. High?purity 316L stainless?steel pneumatic ball valves: On?off      control for cooling?water, compressed?air and protective?gas utility      pipelines.

4. Slow?closing check valves: Installed at circulation?pump      outlets to suppress water?hammer and prevent reverse flow, protecting      drawing?tower cooling system.

5. Y?strainers & explosion?proof solenoid valves: Pipeline      impurity filtration and emergency shut?off protection.

Supporting Services Full?set CE certificates, material spectroscopy reports, factory inspection reports and certificate of origin are provided. Complete technical documentation for Indonesian SNI customs clearance is compiled. USD cross?border payment is supported for EPC container?by?container phased shipment. Bilingual technical manuals, remote commissioning guidance and cross?border spare?parts supply are available for long?term local plant maintenance.

Project Benefits

1. High?precision anti?corrosion valves & instruments      stabilize preform vapor?deposition and fiber?coating processes, minimize      product defects caused by flow fluctuation and guarantee yield of G.657      special optical fiber.

2. One?stop fluid?control package covers gas, ultrapure water,      chemicals, cooling?water and wastewater, lowering multi?vendor procurement      workload for EPC contractors.

3. Complete compliance documents ensure smooth customs clearance      and keep milestone of ZTT Indonesia special?fiber expansion project on      track.

4. Equipment is well?adapted to tropical hot?humid salt?fog      environment in Indonesia. Stable fluid systems support capacity ramp?up.      Finished fibers can be exported to North?America with tariff?optimized      overseas production layout.

5. This replicable solution can be referenced for other overseas      optical?fiber preform, drawing and cabling manufacturing projects across      Southeast Asia.
