High Pressure Manifold - Core Piping For Drilling Pump Discharge System

Classification and Application Scenarios

1. By Working Pressure Rating

• Medium-Pressure High-Pressure Manifold: Rated pressure 35 MPa, mostly used for conventional land drilling in shallow and medium-deep wells, matched with 500 and 800-type drilling pumps.
• High-Pressure Manifold: Rated pressure 70 MPa, the mainstream configuration for deep land wells, matched with F1300 and F1600 high-power drilling pumps.
• Ultra-High-Pressure Manifold: Rated pressure 105 MPa, used for 10,000-meter ultra-deep wells, high-pressure oil and gas wells, and offshore platform drilling, matched with the F2200 high-power drilling pump.

2. By Operating Environment

• Land Drilling High-Pressure Manifold: Emphasizes wear resistance and vibration resistance, adapting to field environments such as deserts, gobi, and mountainous areas; dust-proof and easy to assemble/disassemble.
• Offshore Platform High-Pressure Manifold: Besides high-pressure resistance and wear resistance, the entire assembly is given an anti-corrosion coating to resist marine salt-spray corrosion. The structure is compact to fit the confined space of the platform, and is equipped with a waste-fluid collection structure to prevent drilling fluid leakage from polluting the ocean.

Features

• Adopted high strength alloy steel/carbon steel appropriate to specific pressure rating, strict heat treatment technique, rigid quality control as per APl Spec 16C ;
• Equivalent to FMC WECO style Hammer Union with identical size to ensure easy replacement;
• APl Standard LP/NPT, Tubing threaded, and butt-weld end connection available;
• Complete line of standard service and sour gas wing unions in size from 1"-12" with working pressure up to 20000psi, Sour service conform to NACE specification;
• Quality and full style of hammer union seals can be provided in Buna-N, Viton, and Buna-N/Viton with a brass ring, Buna-N/Viton with a stainless steel ring, and Teflon. There are 80 Nitrile, 80 Viton, 90 Viton or upon request.
• The same figure number, size, and pressure rating are interchangeable, making it easy to match male and female subs that are frequently made-up and broken-out.
