DECENT MACHINERY Centrifugal Fan Silencers Pass Bureau Veritas (BV) Inspection for Singapore Government Water & Environmental Project
Posted on2026-07-28
A complete ITP–WPS–UT/VT–FAT quality chain, verified by BV and refined through client engineers' on-site inspection — DECENT MACHINERY delivers silencer solutions built for Singapore's 60–75 dB noise-control regime.
DECENT MACHINERY, a professional manufacturer and exporter of industrial fans and noise-control equipment,announced the successful delivery of its centrifugal fan silencer systems for a key Singapore government water and environmental governance project, with the full quality documentation package — Inspection and Test Plan (ITP), Welding Procedure Specifications (WPS), UT/VT non-destructive testing reports and Factory Acceptance Test (FAT) — witnessed and endorsed by Bureau Veritas (BV).
A Key Singapore Government Water & Environmental Project
The centrifugal fan silencers were supplied to a key Singapore government water and environmental governance program — a national-level infrastructure project executed under Singapore's rigorous public-sector quality and compliance framework. From mandatory advance personnel registration and exclusive site access passes, to government-supervised noise monitoring and multi-level third-party inspection, every stage of the project operates under management and quality-control standards that rank among the most demanding in the global water treatment industry. For confidentiality reasons, project partner names are not disclosed in this release.
Engineered for Singapore's 60–75 dB Noise Limits
Singapore enforces some of the world's strictest construction and industrial noise regulations, with limits held between 60 and 75 decibels and immediate government intervention triggered by any exceedance. Before production began, DECENT MACHINERY's engineering team conducted multiple rounds of technical consultation with the client, repeatedly calculating and verifying parameters against international noise-standard documentation. The centrifugal fan silencer design — including acoustic performance, material selection, overall dimensions and plate thickness — was optimized across several design iterations before the technical package was finalized. Two dedicated engineering delegations traveled to Singapore for face-to-face technical alignment, culminating in the official purchase order.
A Complete Quality Chain: ITP, WPS, UT/VT and FAT
Every stage of fabrication was governed by a client-approved Inspection and Test Plan (ITP), defining hold points, witness points and acceptance criteria from raw material to final dispatch. All welding was executed under qualified Welding Procedure Specifications (WPS/PQR); every welder holds valid certification with 10 to 20 years of pressure-vessel welding experience, and welding test plates passed laboratory examination before mass production was authorized. Non-destructive testing followed the full VT + UT sequence — comprehensive Visual Testing of every weld, then Ultrasonic Testing to detect internal porosity, cracks and subsurface defects. The project concluded with a Factory Acceptance Test (FAT) witnessed by BV, with all instruments carrying valid calibration certificates and every report traceable.
Client Engineers On Site: Refined Inspection, Documented Rectification
Beyond third-party verification, the client dispatched its own engineers to DECENT MACHINERY's facility for a detailed, item-by-item inspection. Their refined review raised specific modification comments — including external weld appearance and local coating film thickness. DECENT MACHINERY responded with a documented rectification program: welds were re-worked from the inside out, external weld beads re-dressed, and coating thickness brought fully within specification, with every step recorded on video and photo. The re-inspection passed in full — demonstrating not a claim of perfection, but a proven, auditable capability to meet the highest acceptance standards.
Inside-Out Quality Verified by Bureau Veritas
Throughout the program, Bureau Veritas (BV) — the internationally accredited inspection body — witnessed testing, reviewed documentation and endorsed the final quality dossier. Unlike manufacturers that focus only on weld surface appearance, DECENT MACHINERY welds are engineered for dual quality: internal integrity and external finish. The complete BV-endorsed document package — ITP records, WPS/PQR, UT/VT reports, coating DFT reports and FAT certificates — was delivered to the client with full traceability from raw material to final report.
3-Layer Coating System for Salt-Air Corrosion Resistance
Singapore's coastal atmosphere demands exceptional anti-corrosion performance for outdoor equipment. DECENT MACHINERY replaced manual grinding with enclosed professional shot-blasting equipment, creating a uniform anchor profile on the steel surface for maximum paint adhesion. A three-layer coating system — anti-rust primer, intermediate coat and protective topcoat — was applied, with dry film thickness (DFT) measured and recorded after every layer. A formal coating inspection report accompanies each centrifugal fan silencer, safeguarding long-term stable operation in high-salinity environments.
Proven Readiness for Singapore-Standard Projects
Completing this project has made DECENT MACHINERY thoroughly familiar with Singapore's high-standard project system — from technical documentation preparation and submission discipline, to welding procedure qualification, multi-level quality inspection, weld acceptance criteria and coating film thickness requirements. For future clients in Singapore and other high-regulation markets, this translates into a measurable advantage: shorter approval cycles, fewer inspection surprises, and a supplier that already speaks the language of the world's most demanding project specifications.
Full Transparency: Video, Photo and Documentary Evidence
Throughout fabrication, inspection and rectification, DECENT MACHINERY maintained an extensive video and photographic record — a level of documentation transparency that allows every client to audit quality remotely, at any time. The full project video is available below.
From technical alignment and welder qualification to BV-witnessed testing and precision anti-corrosion coating, standardized procedures and complete traceable documentation are the quality guarantee DECENT MACHINERY delivers to every high-end client worldwide.
