Oil & Gas Industry |
Malaysia’s oil and gas sector, dominated by PETRONAS (Petroliam Nasional Berhad), is the backbone of the nation’s industrial economy. Werner Flanges supplies critical piping components to both upstream and downstream operations across Malaysia. Our flanges are used in offshore platforms in the Malay Basin, Sabah Basin, and Sarawak Basin, where they withstand harsh marine environments and high H2S concentrations requiring NACE MR0175 compliance. The Pengerang Integrated Complex (PIC) in Johor, one of Southeast Asia’s largest integrated petroleum hubs, utilizes thousands of our flanges in the RAPID (Refinery and Petrochemical Integrated Development) refinery with 300,000 barrels per day capacity. We also supply to PETRONAS Gas Berhad’s gas processing plants and the extensive pipeline network connecting offshore fields to onshore facilities. For LNG operations, our cryogenic-rated flanges serve Malaysia LNG facilities in Bintulu, Sarawak, one of the world’s largest LNG production complexes, handling temperatures down to -196°C. Our products meet stringent PETRONAS Technical Standards (PTS) including PTS 15.35.01 for forged carbon steel flanges. |

With Malaysia’s rapid urbanization, particularly in the Klang Valley, Penang, and Iskandar Malaysia region, water infrastructure expansion requires reliable piping components. We supply flanges to Air Selangor, Penang Water Supply Corporation (PBAPP), SAJ Holdings (Johor), and Syarikat Air Melaka for water treatment plants, pumping stations, and distribution networks. The Langat 2 Water Treatment Plant, one of Southeast Asia’s largest with 1,130 MLD capacity, utilizes our large-diameter carbon steel flanges. For industrial wastewater treatment at factories across Selangor, Johor, and Penang manufacturing zones, our corrosion-resistant stainless steel flanges ensure long service life in chemically aggressive environments |
Frequently Asked Questions (FAQs)
- do your flanges comply with PETRONAS technical standards (PTS)?
- all flanges we manufacture for the Malaysian oil and gas sector are produced in strict compliance with PETRONAS technical standards, specifically PTS 15.35.01 for forged carbon steel flanges and PTS 15.35.02 for stainless steel flanges. we provide complete material traceability, heat treatment documentation, and mechanical test reports that meet PETRONAS vendor requirements. our flanges have been successfully supplied to multiple PETRONAS projects including offshore platforms, gas processing facilities, and the RAPID refinery complex.
- what is the typical delivery time for flanges to Malaysia?
- standard sea freight delivery to Malaysian ports takes 18-22 days to port klang (for kuala lumpur, selangor, and central region), 19-23 days to tanjung pelepas/pasir gudang (for johor), and 22-26 days to east Malaysian ports (kota kinabalu, kuching, bintulu). for urgent requirements such as turnaround projects or emergency replacements, air freight services are available with 5-7 day delivery. lead time for custom manufactured flanges is typically 4-6 weeks from order confirmation to shipment.
- can you supply NACE MR0175 compliant flanges for sour service applications?
- yes, we are experienced in manufacturing NACE MR0175 (now ISO 15156) compliant flanges for sour service applications containing H2S. this includes material selection per NACE requirements, hardness testing to ensure maximum 22 HRC for carbon steel and specific requirements for corrosion-resistant alloys. we provide complete documentation including NACE compliance certificates, hardness test reports, and material certifications. these flanges are commonly supplied to PETRONAS offshore platforms in high-H2S fields and sour gas processing facilities across Malaysia.
- do you offer third-party inspection services in Malaysia?
- while our manufacturing facility is located in India, we welcome and actively support third-party inspection by any internationally recognized inspection agency. Malaysian clients commonly engage TÜV SÜD Malaysia, DNV, Lloyd’s Register, Bureau Veritas, and SGS Malaysia whose inspectors can visit our facility in India for pre-shipment inspection. all inspection costs are typically borne by the client, but we provide full cooperation including material sampling, witness testing, heat treatment verification, dimensional inspection, and documentation review. inspection can be arranged at any stage of manufacturing.
- can you manufacture custom flanges according to our specific drawings?
- yes, custom flange manufacturing is one of our core competencies. we can produce flanges to client-specific drawings and specifications including non-standard bore sizes and thickness, special pressure ratings beyond ASME B16.5, exotic materials such as Inconel, Hastelloy, Titanium, and Monel, modified facing types and surface finishes, special drilling patterns and bolt hole configurations, and flanges with special extensions or attachments. our in-house design team reviews drawings for manufacturability and provides suggestions if needed. typical lead time for custom flanges is 4-6 weeks from drawing approval. we have successfully supplied custom flanges for PETRONAS specialized applications, offshore platforms with unique requirements, and petrochemical plants with proprietary designs.
