DEENPU 3 Inch 5K Manifold Fittings

High-pressure 3 inch manifold fittings for oilfield flowlines and manifolds. Rated up to 5,000 PSI with LPT, BW SCH.160 and SCH.XXS end options.

Product Overview

DEENPU 3 inch 5K manifold fittings provide reliable, high-pressure connection solutions for wellhead manifolds, choke & kill systems, and stimulation flowlines. The product range covers long sweep full-flow tees, long sweep tees, 45° and 90° long sweep ells, 160° standpipe goosenecks, and goosenecks with top outlet. Configurations include threaded LPT and butt weld schedules 160 and XXS, with selected LPT items rated at 3,000 PSI.

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 manufactured from ASTM A216 Grade WCC carbon steel. Precision machining on horizontal machining centers ensures consistent port alignment, wall thickness, and end-connection concentricity.

Standards & Compliance

Weld-end dimensions comply with ANSI B36.10. Threaded connections follow API line pipe specifications. Butt weld ends are supplied with 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

Available configurations include long sweep full flow tee (LSFFT), 160° standpipe gooseneck with top outlet (GSNKTO), 160° standpipe gooseneck (GSNK160), long sweep tee (LST), 90° long sweep ell (LSE90), and 45° long sweep ell (LSE45). End connections include 3" LPT, 3" BW 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., 3 inch, 5,000 PSI)
• Fitting type (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.
