Core Application & Target User Demand
These mud guard and fastening components are specifically compatible with high-pressure reciprocating pumps (matching fluid end assembly NB005.06.00) and industrial slurry transfer equipment. They serve oilfield drilling, mining, and construction enterprises, addressing segmented needs of debris protection, component fastening, and structural stability. The parts resolve key pain points like mud guard loosening, clamp wear, and bolt failure, safeguarding pump components from abrasive slurry damage and ensuring long-term operational reliability.
1. Mud Guard & Clamp Components
Durable mud guard and clamp components form a protective barrier for high-pressure pump systems, solving damage from abrasive slurry, mud, and debris. Suitable for harsh oilfield/mining environments, they secure mud guards in place, prevent particle intrusion into core components, and comply with industrial equipment protection standards, extending overall system service life.

No. | Product Name | Model/Standard | Material | Main Wear Causes | Damage Prevention Notes |
1 | Hexagon bolt: 3/8’’ | ASME B18.2.1 | Alloy steel (8.8 grade), quenched and tempered, compliant with ASME B18.2.1 for medium-load fastening | 1. Thread wear from repeated assembly; 2. Fatigue fracture from pump vibration; 3. Corrosion from slurry seepage. | 1. Use torque wrenches for precise tightening; 2. Apply thread sealant to prevent slurry intrusion; 3. Replace if threads are stripped or corroded. |
2 | Hexagon bolt 1’’ | ASME B18.2.1 | Alloy steel (8.8 grade), high-tensile strength, compatible with heavy-duty mud guard fixation | 1. Bolt head damage from improper tool use; 2. Thread seizure from corrosion; 3. Over-tightening leading to rod deformation. | 1. Use matching hex tools to avoid head stripping; 2. Apply anti-seize agent in corrosive environments; 3. Tighten to specified torque (85-95N·m). |
3 | Spring washer 27 | GB/T93 | Spring steel (65Mn), tempered, compliant with GB/T93 for anti-vibration locking | 1. Elasticity loss from long-term compression; 2. Corrosion leading to breakage; 3. Deformation from excessive bolt torque. | 1. Replace every 5 assembly cycles; 2. Store in dry, sealed containers; 3. Match with bolt size to ensure proper compression. |
On-Site Fault Maintenance Cases
Case 1: Mud Guard Loosening Due to Spring Washer Failure
An oilfield reported mud guard detachment during drilling. Inspection found spring washer 27 (GB/T93) lost elasticity from long-term vibration, causing bolt loosening. Replacing washers with GB/T93-compliant 65Mn parts and retightening bolts per ASME B18.2.1 torque specs fixed the issue; monthly washer inspections prevented recurrence.
Case 2: Clamp Corrosion & Tension Loss
A coastal mining plant’s NB004.06.11.01 clamp corroded and lost tension, leading to mud guard misalignment. Cleaning corrosion, applying anti-corrosion grease, and replacing severely damaged clamps restored fixation; switching to 316 stainless steel clamps for coastal environments extended service life by 80%.
FAQ
No. | Questions | Answers |
1 | Are these components compatible with NB005.06.00 fluid end assembly? | Yes, all parts (mud guard clamp, bolts, clamps) are fully compatible with NB005.06.00 fluid end assembly, ensuring precise fit and reliable fixation for high-pressure pump systems. |
2 | How often should the mud guard assembly be inspected? | Inspect weekly for loosening, debris buildup, or coating damage; clean monthly to remove slurry residue. Replace the assembly if the steel plate is bent or the anti-wear coating is severely peeled. |
3 | Can I use standard aftermarket bolts for replacement? | Yes, hexagon bolts comply with ASME B18.2.1—standard aftermarket bolts of the same size (3/8’’, 1’’) and 8.8 grade can be used, ensuring compatibility and load-bearing capacity. |
