Engineered to withstand rigorous pressure limits, cyclic mechanical stresses, and coastal sub-tropical corrosion environments. 100% inspected with heat-traceable EN 10204 3.1 Mill Test Certification.
In high-pressure piping assemblies handling compressed natural gas, high-temperature steam, and aggressive chemical feedstocks, material microstructures dictate catastrophic failure limits. Viha Steel & Forging delivers closed-die and open-die forgings that eliminate internal shrinkage cavities, gas porosity, and dendritic segregation typical of conventional sand casting.
Forging deforms metal plastically along the fitting contours. Elbows, tees, and swage nipples feature uninterrupted metallurgical grain paths aligned with longitudinal hoop stresses, maximizing impact fatigue thresholds under sudden cyclic pressure hammers.
Manufacturing Class 2000, 3000, 6000, and 9000 socket-weld and threaded fittings. Every piece is hot-forged from solid billets, normalized or solution-annealed, and CNC-machined to tight tolerances compliant with ASME B1.20.1 NPT threads.
Customized heat treatments guarantee low-temperature Charpy V-Notch toughness down to -46°C for ASTM A350 LF2 Class 1 forgings, as well as NACE MR0175 / ISO 15156 hardness compliance for sulfide stress cracking resistance in sour gas networks.
From the alluvial river basins of the Padma and Jamuna to the saline coastlines of the Bay of Bengal, Bangladeshi industrial infrastructure operates under extreme environmental stresses. Our forged components are tailored for specific geographical operational demands.
Serving gas gathering stations, wellheads, and transmission loops managed by Petrobangla subsidiaries (TGTDCL, BGDCL, SGFL) across Sylhet, Bibiyana, and Brahmanbaria.
Targeted at the Matarbari Deep Seaport, Chittagong Port Authority expansion, Payra Maritime Gateway, and Moheshkhali Floating Storage Regasification Units (FSRU).
Vital components for the industrial hubs of Narayanganj, Gazipur, Savar, and Chattogram EPZ where continuous steam and corrosive dye liquors run 24/7.
Engineered for super-critical installations including the Rooppur Nuclear Power Plant balance-of-plant, Rampal Power Station, and Ghorashal-Polash Fertilizer.
The transition from traditional commercial trading to specification-driven procurement across Bangladesh requires EPC contractors to upgrade material safety factors and regulatory documentation.
Following stringent industrial safety audits under national safety directives and international inspection frameworks (e.g., RSC - RMG Sustainability Council), Bangladeshi plants are dismantling brittle grey-iron and malleable cast fittings. Procurement protocols now mandate hot-forged ASTM A105/A182 fittings to safeguard boiler rooms against catastrophic ruptures.
As domestic gas wells mature, Bangladesh’s rising dependency on imported re-gasified LNG (RLNG) has driven massive infrastructure investments. This has sparked exponential demand for ASTM A350 LF2 low-temperature fittings and cryogenic stainless austenitic forgings capable of retaining notch ductility under thermal contractions.
Constrained foreign currency reserves have accelerated the shift toward rigorous, verifiable documentary credit via Bangladesh Bank regulations. Bangladeshi buyers now bypass intermediate traders to engage directly with certified manufacturers capable of delivering accurate mill certificates and third-party inspection sign-offs.

Founded in Mumbai in 2010, Viha Steel & Forging has developed into an internationally accredited, PED 2014/68/EU-approved manufacturer and premier exporter of high-integrity industrial fasteners, forged pipe fittings, and ASME B16.5 flanges. Operating as an active member of the Fastener Manufacturers Association of India (FMAI), we bridge the gap between raw metallurgical science and heavy field performance.
Our expansive production works house modern closed-die forging hammers, induction billet heaters, specialized CNC multi-axis thread turning machines, and in-house heat treatment furnaces. We are proudly recognized among India's largest exporters of hot-dip galvanized fasteners and heavy alloy components.
Addressing the exact commercial, legal, and engineering questions raised by project developers, supply chain officers, and indentors across Dhaka and Chattogram.
We routinely execute shipments under Irrevocable Letters of Credit (LC at Sight) issued by reputable Bangladeshi commercial banks (such as Eastern Bank, City Bank, BRAC Bank, Islami Bank Bangladesh, and Standard Chartered Dhaka) with Bangladesh Bank foreign exchange compliance. Our export trade desk ensures exact consistency across Bills of Lading, Commercial Invoices, Packing Lists, Certificates of Origin, and Mill Test Certificates to ensure discrepancy-free negotiation.
Yes. Many government, semi-government, and international EPC contracts in Bangladesh mandate pre-shipment inspection (PSI/TPI). We routinely facilitate inspection engineers from SGS, Bureau Veritas, TÜV SÜD, DNV, and Lloyd’s Register at our manufacturing plant for witnessing dimensional verifications, chemical spectrometry, tensile pulls, Charpy impact tests, and hydrostatic pressure containment.
Consignments originating from our production and warehousing hubs in Mumbai are routed via Nhava Sheva (JNPT) or Mundra Port directly to Chittagong Port (Chattogram CPA). Typical container sea transit time ranges from 10 to 16 days. For emergency outage MRO replacements or shutdown items, express air-cargo shipments can be coordinated through Hazrat Shahjalal International Airport (DAC) in Dhaka within 48 to 72 hours.
Bangladesh’s severe monsoon season and high relative humidity during inland barging or highway transit (Dhaka-Chittagong corridor) can cause rapid galvanic or atmospheric flash rusting on standard bare steel. All our forged carbon steel fittings receive rust-preventative dipping (black phosphate, transparent anti-rust oil, or electro-galvanizing). Products are hermetically sealed inside thick VCI (Vapor Corrosion Inhibitor) plastic bags before being packed into ISPM-15 compliant, heat-treated wooden crates banded with steel strapping.
We classify products strictly under standard international tariff headings to prevent clearance disputes or customs penalty holds at Chittagong customs houses. Generally, forged pipe fittings (elbows, tees, couplings, unions) fall under HS Code 7307.92 / 7307.99; forged steel flanges are cleared under HS Code 7307.21 / 7307.91; and threaded structural fasteners/bolts are classified under HS Code 7318.15 / 7318.16.
Yes. Our in-house tooling division creates custom forging dies and precision CNC turning programs based on client blueprints. Whether your project requires non-standard reducing socket tees, custom metric/imperial adapters, extended swage nipples, or high-tensile titanium and nickel alloy bolting, our engineers deliver prototypes and full production runs accompanied by 3D CMM inspection reports.
Eliminate intermediary costs, reduce delivery lag times, and reinforce structural integrity with fully certified, heat-traceable forged pipe fittings, flanges, and high-tensile fasteners. Our dedicated South Asian technical export desk is ready to review your project Bill of Quantities (BOQ).
