DEENPU 4 Inch 5K Manifold Fittings
High-pressure 4 inch manifold fittings for wellhead manifolds and flowlines. Rated up to 5,000 PSI with LPT, BW SCH.80/160/XXS end options.
Product Overview
DEENPU 4 inch 5K manifold fittings are built for severe-duty oilfield flowline service. The range includes full flow crosses, long sweep full-flow tees, long sweep tees, 45° and 90° long sweep ells, 90° ells with 2 inch top outlet, 160° and 180° standpipe goosenecks, and long sweep Y fittings. Multiple end connection options and precise casting geometry provide reliable performance in high-pressure manifolds.
Key Features
- Long sweep radius design minimizes turbulence and pressure drop for high-flow applications.
- Full flow paths on cross and full-flow tee configurations reduce erosion and improve service life.
- Precision-machined cast bodies to tight tolerances on horizontal machining centers.
- Interchangeable end connections: threaded LPT, butt weld SCH.80/160/XXS, and special connections on request.
- Hydrostatically tested to 1.5 times the working pressure before delivery.
- Sour gas service configurations available for H₂S-bearing environments.

Note: On butt weld fittings, the weld bevel is 37.5°. The O.D. and I.D. of weld end fittings match ANSI B36.10. Dimensions apply to both weld end and screwed end fittings.
Materials & Manufacturing
Castings are made from ASTM A216 Grade WCC carbon steel, machined to close tolerances on horizontal machining centers for superior port alignment and wall thickness consistency.
Standards & Compliance
Weld-end dimensions conform to ANSI B36.10. Threaded connections comply with API line pipe specifications. Butt weld ends feature a 37.5° bevel. Hydrostatic testing is performed to at least 1.5 times rated working pressure.
Applications
- High-pressure wellhead and manifold flowlines
- Choke and kill line assemblies
- Fracturing and flowback operations
- Cementing and stimulation manifolds
- Mud and drilling fluid distribution systems
- Sour gas production and well-testing service
Available Configurations
Configurations include full flow cross (FFC), long sweep Y (LSY), 160° gooseneck with top outlet (GSNKTO), 160° gooseneck (GSNK160), 180° gooseneck (GSNK180), 90° long sweep ell with 2" top outlet (424LSE90), 45° long sweep ell (LSE45), 90° long sweep ell (LSE90), long sweep full flow tee (LSFFT), and long sweep tee (LST). End connections include 4" LPT, BW SCH.80, SCH.160, and SCH.XXS.
Inspection & Documentation
Every fitting is hydrostatically tested to a minimum of 1-1/2 times the rated working pressure. DEENPU provides material test reports, dimensional inspection reports, and hydrostatic test certificates on request. Traceability records are maintained for all pressure-retaining castings.
Packing & Delivery
Fittings are cleaned, preserved, and packed in robust wooden crates or export-standard cartons suitable for ocean and air freight. Threaded and weld-end protectors are fitted to prevent damage during transit. Packing lists and inspection documents are included with each shipment.
Information Required for Quotation
Please provide the following details so we can prepare an accurate quotation:
- Nominal size and pressure rating (e.g., 4 inch, 5,000 PSI)
- Fitting type (cross, tee, ell, gooseneck, etc.)
- End connection specification (LPT, BW SCH.80/160/XXS, or special)
- Material grade and sour gas requirement, if applicable
- Quantity required and delivery destination
FAQ
Q: What end connections are available?
A: Standard connections include API line pipe threaded (LPT) and butt weld schedules 80, 160, and XXS. Special end connections such as socket weld or metric threads can be supplied on request.
Q: Can these fittings be used for sour gas service?
A: Yes. Sour gas service versions are available. Please specify H₂S service when requesting a quotation so we can confirm material grade and compliance.
Q: What testing is performed before shipment?
A: All manifold fittings are hydrostatically tested to at least 1.5 times the rated working pressure. Material and test certificates are available on request.
Q: How do I choose the right schedule for butt weld ends?
A: Schedule selection depends on the working pressure and piping specification. SCH.160 and SCH.XXS are common for 5,000 PSI service; SCH.80 is typically rated for 3,000 PSI in selected sizes.
