“We replaced a welded header with the 4000 Series on a sulfuric acid concentration loop. The volumetric drift we used to see after 200 hours is gone — pressure stays within 0.3 bar across the entire campaign.”

“The GDM-200 let us add three new reactor feeds without shutting down the main line. Each port holds its setpoint within 1.5% even when we cycle the adjacent valves. No re-piping, no downtime.”

“Our skid footprint was the bottleneck. The HDC-8 collector block cut the feed piping length by 40% and eliminated three threaded joints that used to leak under thermal cycling. Retrofit took one shift.”

“We run a continuous chlorination loop at 42 bar. The 4000 Series header has logged 3,800 hours without a single flange reseal. The volumetric flow curve is flatter than anything we’ve tested.”

Definitions and scope of supply

Clarifications on manifold engineering

What is the maximum operating pressure for the GDM-200 manifold?

The GDM-200 multi-port gas distribution manifold is rated for continuous operation up to 300 bar at 120°C. Each port is individually tested to 1.5 times the rated pressure. For applications exceeding these parameters, please consult our engineering team for a custom-rated assembly.

Are the flanges on the HDC-8 collector block compatible with ANSI 150# standards?

Yes, the HDC-8 heavy-duty collector block is machined with ANSI 150# bolt patterns as standard. Optional configurations for ANSI 300# and DIN PN16 are available upon request. The block itself is rated for 250 bar, so flange selection depends on your piping class.

Does the 4000 Series steam header include isolation valves?

The High-Pressure Steam Header 4000 Series is supplied as a bare header with pre-drilled port flanges. Isolation valves are not included but can be integrated as a custom option. The header body is designed to accept standard gate or globe valves with minimal modification.

What material is used for the manifold body in corrosive chemical loops?

Standard construction is ASTM A182 F316L stainless steel for resistance to chlorides and acidic media. For highly aggressive environments, we offer Hastelloy C-276 and Inconel 625 as upgrade options. Material certification and traceability are provided with every unit.

Can the GDM-200 be expanded after initial installation?

Yes, the modular design of the GDM-200 allows field expansion by adding port blocks. Each block adds up to four outlets, and the manifold can be extended to a maximum of 24 ports. Expansion kits include gaskets, bolts, and pressure-test documentation.

What is the lead time for a custom steam header configuration?

Standard configurations ship within 4–6 weeks. Custom headers with non-standard port spacing, special materials, or integrated instrumentation require 8–12 weeks from engineering approval. We provide a detailed project schedule at the time of order confirmation.
