Marine High Pressure Manifold Manufacturer Checks: Is This Choke Manifold the Right Fit?
When a procurement team starts looking for a marine high pressure manifold manufacturer, the first job is to decide which product category the project needs and which operating conditions it has to handle. This guide explains how to check one documented product, the Choke Manifold from Hebei Hongru Petroleum Machinery Co., Ltd., against your requirements. It also shows where the published information ends.
Start with the application, not the keyword
The product material describes this Choke Manifold as a high-pressure assembly for fluid flow control during oil and gas production and well logging at the wellhead. It uses a series of nozzles and throttles so operators can monitor pressure, temperature and production capacity.
Specification checks to run
Compare your project data sheet with the parameters published for the product:
| Criterion | Published value | What to confirm |
|---|---|---|
| Working pressure | 42 MPa ~ 105 MPa | The rating your well or system needs, plus your design margin |
| Nominal diameter | 2 1/16" ~ 4 1/16" | The bore that matches your flow lines |
| Temperature rating | -29°C ~ 121°C (P+U) | Your minimum and maximum fluid and ambient temperatures |
| Sour service | H2S compatible (NACE MR0175) | Whether your fluids contain H2S and what documentation you need |
| Connection type | Flange / union connection | How it will interface with your existing pipework |
| Valve type | Flat gate valve | Whether this valve type fits your operating practice |
| Material process | High-strength forging | The material records you need for your files |
| Standard compliance | API specifications | The exact API specification and edition your project calls for |
| Configuration | Customizable | Your throttling and layout requirements |
If any of your requirements fall outside these ranges, the product as published doesn't apply. You would need to raise that with the manufacturer.
Sour gas and corrosive service
The product is listed as compliant with NACE MR0175 for H2S-rich sour gas environments. It is also described as designed for long-term operation in corrosive fluids, with wear-resistant components. For sour-service projects, ask for the documents that support compliance for your specific order, such as material and test records.
Connections and installation
The published design uses forged flange four-way structures and union connections, which the material says make field pipeline installation simpler. Before ordering, check that the flange and union ends match the connections on your existing equipment.
Customization
The material says throttling forms can be tailored to user requirements. If you need a non-standard layout, prepare your pressure, flow and control requirements in advance so the manufacturer can review them in a quotation.
What this guide does not cover
Summary checklist
- Confirm the application: wellhead production or well logging.
- Check that pressure, bore size and temperature fall within the published ranges.
- Confirm your sour-service needs and the NACE MR0175 documentation.
- Check that the flange and union connections match your pipework.
- Define any custom throttling layout.
- Ask for written confirmation of API scope, pricing and delivery.
