Mud Tank Parts List: GK175.10.01.00 & 51112 Compatible Components

Introduction: Why Quality Mud Tank Parts Are Critical for Drilling Mud System Reliability

If you’re a field engineer working on drilling rigs, you know how vital a properly functioning mud tank is to your operation. The mud tank is the heart of the drilling mud system—it stores, circulates, and conditions the drilling mud that cools the drill bit, removes cuttings, and maintains wellbore stability. But here’s the harsh truth: a single faulty mud tank part can derail your entire operation. Imagine your GK175.10.01.00 extended rod butterfly valve fails to seal, causing mud leaks that waste thousands of gallons of expensive drilling fluid. Or your 51112 thrust ball bearing seizes, jamming the rotary mud gun (GK175.10.02.00) and stopping mud circulation. Suddenly, you’re facing unplanned downtime, costly fluid loss, and even wellbore instability—all because of a part that didn’t hold up. Every component in your mud tank, from the smallest 54.5×3.55-G-N O-ring to the largest 76Ⅰ-10000N3 hose assembly, plays a make-or-break role in keeping your mud system running smoothly. Cutting corners on replacement parts isn’t just inefficient—it’s a risk to your well’s integrity, your team’s productivity, and your bottom line. That’s why we’ve built this parts list specifically for drilling mud tanks, focusing on the components you rely on most, engineered to withstand the harsh conditions of陆上 and offshore drilling sites.

Product Overview

This mud tank parts list includes 74 essential components, each engineered to support the critical functions of drilling mud tanks. From fluid transfer components like the 76Ⅰ-2000N3, 76Ⅰ-10000N3 hose assemblies and GK175.10.01.00 extended rod butterfly valve to sealing components like the HTGK500.38.15.01 O-sealing ring and V42×32×16 sealing ring, every part is manufactured to the highest standards for durability and performance. We’ve covered every key system of the mud tank: fluid circulation (rotary mud gun GK175.10.02.00, bottom valves GK175.10.03.00 and DN200-PN10-RF), fluid control (butterfly valves DMD7L1X7-150LBZB series), connection (quick change joints HTGK26.00, HTGK08.00, clamp quick change joint DN200/KRG-PN25/D219), sealing (O-rings, O-sealing rings, rubber joints KDTF×1.0/DN100), load-bearing (51112 thrust ball bearing), and fastening (hexagonal head bolts, flat washers, spring washers). Each part is precision-machined to ensure perfect fit with standard mud tank models, eliminating the frustration of ill-fitting components that cause leaks, blockages, or premature failure. Whether you need a single replacement O-ring or a full set of hose assemblies, every component here is built to the same rigorous standards, so you can trust in consistent quality across the board.

Function Description

Every part in this list serves a critical function in keeping your mud tank and mud system operational—let’s break it down like we do on the rig. The GK175.10.01.00 extended rod butterfly valve controls the flow of drilling mud into and out of the tank, allowing you to regulate flow rate and isolate sections of the mud system for maintenance—without it, you can’t control mud circulation. The 51112 thrust ball bearing supports the rotary mud gun (GK175.10.02.00), reducing friction and allowing it to spin freely, ensuring even mud agitation and preventing solids from settling at the bottom of the tank. Hose assemblies (76Ⅰ series, 102Ⅰ-1680N4) transfer drilling mud between the tank and other components (pumps, shakers, centrifuges), with varying lengths (2000mm to 10000mm) to fit different rig configurations. Quick change joints (HTGK26.00, HTGK08.00) allow for fast, tool-free connection and disconnection of hoses, reducing maintenance time. Sealing components (O-rings, O-sealing rings, V42×32×16 sealing rings) keep mud contained, preventing leaks that waste fluid and contaminate the work area. Fasteners like the 5/8″-11×3 1/4″ hexagonal head bolt and 16 spring washer keep components securely fastened, even in high-vibration environments—loose fasteners can lead to misalignment, leaks, and component damage. Even small parts like the 54.5×3.55-G-N O-ring play a role, creating a tight seal in valves and joints to prevent mud seepage. Every part works together to keep your mud system running smoothly, so you can focus on drilling.

Structural Features

As field engineers, we know that mud tank parts have to stand up to some of the harshest conditions in drilling—abrasive mud solids, corrosive chemicals (like drilling additives), high pressure, and constant vibration. That’s why each part is designed with structural features that prioritize durability and performance. The GK175.10.01.00 extended rod butterfly valve features a cast iron body with a stainless steel disc, resistant to corrosion and wear, and a reinforced extended rod that prevents bending under pressure. The 51112 thrust ball bearing is made from high-carbon chromium steel with a hardness of 62 HRC, capable of handling axial loads up to 47,800 N without deformation. Hose assemblies (76Ⅰ series) are constructed with a synthetic rubber inner layer (resistant to drilling mud and chemicals), a steel wire reinforcement layer (for pressure resistance up to 25 MPa), and a weather-resistant outer layer (for protection against UV and extreme temperatures). Sealing components are made from nitrile rubber (NBR) or fluorocarbon rubber (FKM), with the 54.5×3.55-G-N O-ring featuring a Shore A hardness of 70, ensuring a tight seal even under high pressure. Fasteners are made from high-strength alloy steel (grade 8.8) with zinc plating for corrosion resistance, and precision-threaded to ensure a secure fit. All parts are precision-machined with tight tolerances (±0.002 inches for critical components like bearings and valves), ensuring perfect fit and reducing wear caused by friction or misalignment.

Applicable Working Conditions

These mud tank parts are built to perform in the most extreme drilling environments—no matter where your rig is located. They’re fully compatible with both陆上 and offshore drilling sites, including high-temperature, high-pressure (HTHP) wells, corrosive saltwater environments, and dusty, high-vibration land rigs. All parts can operate reliably in a temperature range of -40°F to 300°F, making them suitable for arctic oilfields in Alaska or hot desert fields in Saudi Arabia. They’re designed to withstand operating pressures up to 25 MPa (3626 psi), compatible with standard mud system pressures (10-20 MPa). For offshore rigs, parts like the GK175.10.01.00 butterfly valve and HTGK500.38.15.01 O-sealing ring are treated with anti-corrosion coatings to resist saltwater damage, passing 1,200 hours of salt spray testing (ASTM B117) with no visible rust. In muddy, abrasive environments, hose assemblies (76Ⅰ series) resist wear from solid particles, with a service life of 3,000+ hours in heavy mud conditions. Whether you’re drilling on land, offshore, in cold, heat, or high pressure, these parts are engineered to keep your mud tank running without failure.

Maintenance Tips for Field Engineers

I’ve spent years maintaining mud systems on drilling rigs, and I can tell you—proactive maintenance is the key to avoiding costly downtime and fluid loss. Here are the practical tips I share with my team to keep mud tank parts in top shape: First, inspect all hose assemblies (76Ⅰ series, 102Ⅰ-1680N4) weekly for cracks, bulges, or leaks—replace any hose that shows signs of wear, as a burst hose can waste hundreds of gallons of mud. Second, lubricate the 51112 thrust ball bearing every 300 operating hours with NLGI Grade 2 lithium grease, and check for mud contamination (if the grease is cloudy or contains solids, clean the bearing and replace the grease). Third, torque fasteners to the correct specifications: 5/8″-11 hexagonal head bolts need 65 ft-lbs, 3/4″-10 bolts need 110 ft-lbs, and 7/8″-9 bolts need 180 ft-lbs—over-torquing can strip threads, under-torquing causes loosening. Fourth, replace O-rings (54.5×3.55-G-N, HTGK500.38.15.01) every 1,500 hours, or if you notice leaks—even a small O-ring leak can waste mud and damage other components. Fifth, clean the GK175.10.02.00 rotary mud gun monthly to remove mud buildup, and check the 51112 bearing for smooth rotation. Finally, store spare parts in a dry, clean area (between 60°F and 80°F) to prevent contamination and material degradation—this is especially important for bearings and O-rings, which can degrade if exposed to mud or moisture.
