Custom Oilfield Equipment Components Manufacturers

Anhui Exwell New Energy Technology Co., Ltd. is a Custom Oilfield Equipment Components supplier focused on petroleum industry spare parts. From our 20-acre manufacturing base in Wuhu, Anhui, we produce fluid ends, power ends, mud pumps, housings, assemblies and custom spare parts for oil extraction, drilling and refining operations. Our components are engineered as direct replacements for leading pump systems, including SPM, Halliburton, GD and FMC series, and are supplied to oil and gas projects worldwide.

We support both standard replacement parts and fully customized components based on customer drawings, samples or worn parts. Our annual production value of USD 85.7 million and export volume of USD 34.2 million reflect the scale and supply chain maturity we bring to well service, cementing, acidizing, fracturing and drilling programs.

Product Range for Oilfield Equipment

Our catalog is organized around the core pressure-containing and drive components of reciprocating pumps. Each family is available in carbon steel or stainless steel, with configuration options matched to the working pressure, plunger size and service environment.

Additional product families include Mud Pump Housing, Mud Pump Assembly, JWS-400 Triplex Well Service Pump, Spare Part and Custom Spare Part. Each category is supported by our in-house machining, testing and quality control processes.

Application Fit and Engineering Value

Our components are specified for high-pressure reciprocating pump service across the well lifecycle. The table below summarizes typical applications and the corresponding product families we configure.

We select materials and heat treatment based on the working fluid, pressure cycling and abrasive conditions. Carbon steel is standard for most well service applications; stainless steel is available where corrosion resistance or fluid compatibility is required.

Critical Specifications and Configuration Options

Each product family is defined by stroke length, plunger configuration, material grade and dimensional envelope. We maintain these parameters to ensure direct interchangeability with the original equipment.

• HT400: 8" stroke, triplex, plunger sizes 4"–4.5", load weight 2,240 lb, replacement for Halliburton.
• TWS600S: 6" stroke, triplex, plunger sizes 2.75"–4.5", load weight 1,550 lb, replacement for SPM.
• QWS1000: 6" stroke, quintuplex, plunger sizes 2.75"–4.5", load weight 2,500 lb, replacement for SPM.
• TWS2000: 8" stroke, triplex, plunger sizes 4"–5.5", max working pressure 17,916 psi, replacement for SPM.
• TWS2250: 8" stroke, triplex, plunger sizes 4"–6", load weight 3,350 lb, replacement for SPM and GD.
• TWS2500: 10" stroke, triplex, plunger sizes 4"–5.5", net weight 6,577 kg, replacement for SPM.

For power ends, we configure gear ratio, maximum rod load, brake horsepower and overall dimensions to match the pump frame. For example, the QWS1000 power end is rated at 2,250 BHP with a 6.353:1 gear ratio and 225,000 lb maximum rod load.

Customization and Manufacturing Process

Customized production is our core business. We can develop components from customer drawings, samples, or even worn parts that require reverse measurement. The process follows five defined stages:

1. Drawings/Samples & Feasibility Analysis: Customer submits drawings or samples to clarify customization requirements.
2. Technical Assessment & Parameter Recommendation: Our engineering team evaluates the working conditions and confirms a feasible solution.
3. Quotation: We calculate costs accurately and issue a formal quotation.
4. Proofing: Customized sample production and sample testing confirmation.
5. Mass Production: Standardized production with quality and quantity guaranteed delivery.

Our factory is equipped with Czech TOS CNC boring and milling machines, Mazak horizontal boring and milling machining centers, Okuma gantry machining centers, quantitative CNC machining centers, gantry cranes and a dedicated polishing room. This equipment supports high-precision machining of large oilfield components.

Quality Assurance and Testing

We implement full-process quality management. After each production step there is an inspection, and final inspection of finished products is 100% according to customer requirements and international standards. Our in-house laboratory and testing equipment cover:

• Material physical and chemical property testing
• Non-destructive testing (NDT)
• High-precision geometric dimension detection using Leader CMM
• Pressure and sealing performance testing

All inspection reports are provided with the cargo together. For mud pump housings and assemblies, we follow API Spec 7K design and hydro test requirements, with standard cylinder hydro test pressures of 7,500 psi for F Series and 10,000/11,250 psi for P Series.
