Full Lifecycle After-Sales Service to Secure Stable Equipment Operation—After-Sales Service Practice Report of Wensheng Instrument

Stable equipment operation serves as the foundation for steady progress of long-distance oil & gas transmission pipelines and oilfield projects. The execution quality of after-sales service directly affects equipment service life, project operation efficiency and production safety. Shenyang Wensheng Instrument & Equipment Co., Ltd. has long focused on R&D, manufacturing and supporting services of non-standard equipment for oil and gas pipelines. Our core products cover pipeline supporting equipment including cleaning pig equipment, insulating joints, the Pig Receivers, the Pig Launchers, separation filters and more.

Drawing on abundant practical experience from numerous projects, the company has built an after-sales service system covering the full lifecycle of equipment. Supported by unified service standards, rapid response and professional technical support, we ensure stable regular operation of all types of pipeline equipment and provide services for major domestic oil and gas engineering projects.

With more than 20 years of experience in the oil and gas pipeline equipment industry, we continuously serve energy enterprises including CNPC, Sinopec, CNOOC and China PipeNetwork. We have cooperated with over one hundred clients. Thanks to practical and reliable after-sales support accumulated from long-term project cooperation, we maintain solid customer loyalty with consistent service quality.

1. Dedicated Technical Team to Sustain Regular After-Sales Support

Effective after-sales implementation relies on stable professional manpower. We have set up an exclusive after-sales technical service team with 35 professional staff, including 9 senior engineers, 5 assistant engineers and 5 professional non-destructive testing technicians.

All team members possess in-depth expertise on non-standard oil & gas pipeline equipment. They are familiar with structural principles, installation specifications, troubleshooting methods and daily maintenance requirements of our full product lineup: Quick Opening Closure, The Pig Receivers, The Pig Launchers, insulating joints and all types of cleaning pigs (The cleaning pig, polyurethane foam pig, polyurethane cup pig, polyurethane disc pig, elastic scraper pig, magnetic polyurethane pig, diameter changes pig, integrated intelligent pig with diameter measurement, steel brush pig etc.). Our team can handle after-sales demands for both standard and custom non-standard equipment.

We adopt an exclusive customer liaison mechanism throughout project cooperation. Each project is assigned fixed technical staff to manage the whole workflow: factory inspection coordination, installation guidance, equipment commissioning and acceptance, and follow-up operation and maintenance.

For remote oilfields, long-distance transmission pipelines and overseas projects, remote technical support channels are available on demand to ensure the timely resolution of equipment faults. All after-sales operations, equipment inspection and maintenance records are properly archived to realize full traceability, matching the regular operation management requirements of oil and gas projects.

2. Closed-Loop Full-Process Service Covering the Complete Equipment Lifecycle

Our after-sales service runs through all phases: equipment selection, field installation, commissioning operation and long-term maintenance, forming a closed-loop service mode. We avoid the common practice that prioritizes delivery while neglecting maintenance. Centered on clients’ actual operational demands, we deliver comprehensive basic after-sales services.

In the equipment coordination phase, our technicians provide free technical consultation and equipment selection services based on project operating conditions, pipeline pressure, medium type and site environment. For customized non-standard equipment, we continuously coordinate drawing confirmation and process adaptation to guarantee products fit on-site working scenarios from the source.

After equipment delivery, our technicians provide full follow-up services including operation guidance, equipment commissioning, tightness inspection and operation parameter calibration. We ensure qualified installation, matched working parameters, smooth acceptance and startup to guarantee projects go online as scheduled.

Once equipment is put into service, we deliver training for operators and maintenance personnel, covering standard operation procedures, safety specifications, basic troubleshooting and periodic maintenance essentials. Training helps field staff master operation and routine maintenance skills and reduce failure frequency.

Meanwhile, we maintain a regular inventory of spare parts. Key components and wear parts are stocked persistently to quickly respond to replacement requests and prevent pipeline shutdowns caused by parts shortages.

After project handover, we provide long-term technical support and maintenance tracking. We conduct regular client visits to record equipment operating status, offer targeted suggestions on working condition adaptation, maintenance optimization and technical upgrading, and assist customers in tackling various technical issues during equipment operation.

3. Standardized Response Mechanism for Efficient Fault Handling

To guarantee timely after-sales support, we establish a complete service response system with a national unified service hotline to receive consultation, fault reporting and maintenance requests all year round. Online daily inquiries are replied promptly. For sudden equipment breakdown within China, remote technical diagnosis and solutions are offered within 24 hours.

For overseas cooperative projects, dedicated remote operation & maintenance channels are available, providing 24-hour online troubleshooting, parameter debugging and technical consultation to safeguard stable operation of equipment for domestic and international projects.

In terms of the warranty policy, standardized warranty terms are implemented. General equipment warranty lasts 3 years. For core components such as sealing assemblies and drive systems, a maximum 5-year warranty can be provided to effectively lower clients’ equipment operation costs.

4. Proven Project Experience Builds a Sustainable Market Reputation

Over two decades of project practice continuously verifies the quality of our after-sales service. In long-running projects such as the Sinopec Pearl River Delta refined oil pipeline, our supplied Quick Opening Closure and other equipment operate continuously under high loads for years with stable sealing performance and zero leakage failures. Project owners recognize our equipment reliability and follow-up maintenance services.

Most cooperating clients comment that our equipment features strong adaptability and stable operation. Our after-sales communication is smooth; staff respond rapidly, actively track equipment status and accurately resolve practical challenges during project operation, securing safe and steady long-term pipeline operation. Reliable product quality and sustainable after-sales guarantee support stable repeat orders and long-term partnerships. Our services cover most oil & gas producing zones in China and multiple overseas regions.

Looking ahead, Shenyang Wensheng Instrument & Equipment Co., Ltd. will continue to focus on clients’ actual maintenance needs. We keep optimizing after-sales workflows, refining service standards and upgrading technical capabilities to steadily deliver a full-lifecycle after-sales guarantee. With solid service and consistent quality, we keep providing reliable supporting solutions for safe and stable operation of oil and gas pipeline engineering projects.
