Our heavy-wall distributor, collector, and mixing steam headers are designed to handle pulsating steam dynamics and thermal expansion cycles. Built from seamless alloy pipes with hot-pulled extruded stubs or full-penetration welded forged weldolets, our headers eliminate stress concentration points and flow turbulence.
Generating bank tubes connect the upper steam drum to the lower mud drum in bi-drum water-tube boilers. Precision bent on computerized mandrel benders, each tube is guaranteed to exact curvature templates. Specially annealed tube ends ensure zero-leak roller expansion tightness into drum tube holes without work-hardening or micro-cracking.
Modern Boilers feedwater storage tanks and deaerator columns prevent boiler tube pitting and dissolved oxygen corrosion. By elevating water temperature to 105°C and stripping non-condensable gases below 0.005 cc/liter, our vessels ensure reliable suction head for high-pressure feedwater pumps and buffer boiler surge loads.
