Critical Valve Requirements

BFG valves must accommodate sticky tar deposits - knife gate or through-conduit design; no wedge gate (tar packs the body cavity)

Large-bore butterfly valves for BFG (DN600–DN2400) - double-offset design for bubble-tight shutoff required at change of wind direction

IBR certification mandatory for all steam valves above 3.5 kg/cm² in Indian steel plants - Form III-C material and Form III-E hydrostatic test

Blast furnace water cooling valves - continuous service, no shutoff allowed; use dual parallel valves for maintenance

Coke oven gas (COG) - naphthalene deposition blocks small ports; use full-bore valves only; minimum DN50

IS 6157 compliance for BFG gate valves manufactured in India

Why Mailiao's Integrated Petrochemical Sector Needs Coke Oven & Steel Plants Valves

Mailiao in Yunlin County hosts the Formosa Petrochemical (FPCC) Mailiao complex, one of the world's largest integrated petrochemical sites built around the Sixth Naphtha Cracker with a refinery, multiple olefins and aromatics trains, polymer plants, and captive cogeneration, served by a dedicated industrial port; naphtha-cracking, olefins, and polymer service drives demand for API 6D ball and gate valves in carbon and alloy steel for cracker, quench, and fractionation loops, cryogenic valves for ethylene and light-ends, low-fugitive-emission and bellows-seal valves for VOC service, high-temperature globe and check valves for furnace and steam systems, and API 526 relief valves; ASME B16.34, API standards, and international EPC specifications apply with full material certification and PMI; Vajra Industrial Solutions supplies Mailiao petrochemical operators and Taiwanese EPC contractors with cracker-grade, cryogenic, and low-emission valve packages with East Asia logistics. Key facilities in the Mailiao area - including Formosa Plastics FPCC Mailiao complex, Mailiao industrial port, Sixth Naphtha Cracker (No.6 Naphtha) - rely on Knife Gate Valve for their cogeneration power operations.

Why are knife gate valves preferred for blast furnace gas?

Conventional wedge gate valves trap BFG tar and dust in the body cavity, causing the gate to seize. Knife gate valves have no body cavity - the blade cuts through the medium with a shear action, shedding deposits on actuation. The flat-face gate also allows easy replacement in-situ when the knife edge wears, without removing the body from the pipeline. For large BFG mains (DN600–DN2400), double-offset butterfly valves are preferred over knife gates for better shutoff and lower actuator torque.

What IBR documentation is required for steel plant steam valves?

All steam valves above 3.5 kg/cm² must carry IBR Form III-C (Certified Material Test Report from the steel mill, showing heat number, chemical analysis, and mechanical test results) and IBR Form III-E (Hydraulic Test Certificate from the valve manufacturer, showing test pressure = 1.5 × rated working pressure held for ≥ 30 minutes). Vajra supplies both certificates as part of the standard documentation package for all IBR-certified valves.
