I. Project Overview
In 2025, a South African oil and gas engineering company purchased industrial pipeline valves in bulk from Yuming Valve Group for a regional natural gas pipeline network upgrade project. The purchased valves included American Standard WCB flange ball valves, cast steel gate valves, swing check valves, basket filters, and safety valves, for use in local natural gas transportation, process pipeline shut-off, media filtration, and pressure relief. Leveraging over 10 years of practical experience in foreign trade valve projects, and considering the high temperature, dryness, and large diurnal temperature variations in South Africa, we provided the client with a complete valve selection, factory testing, export wooden crate packaging, and cross-border logistics delivery service. This order was shipped in three batches, and all products passed factory testing. As of April 2026, all valves had been successfully delivered to the South African project site.

II. Client's Core Needs
- Operating Conditions and Adaptability Requirements: The valves are used in South African onshore natural gas pipelines carrying clean natural gas. The valve bodies must be corrosion-resistant, leak-free, and adaptable to the high temperatures and dusty outdoor environment, with a stable and durable service life.
- Product Standard Requirements: Main ball valves, gate valves, and check valves must comply with American API and ASME standards, be made of WCB carbon steel, and meet Class 150 pressure rating. Filters and safety valves must adopt national standard designs to meet on-site pipeline installation size requirements.
- Delivery and Compliance Requirements: Products must be rust-proof and dust-proof, packaged in fumigated solid wood export crates, and require technical support and an 18-month warranty from the factory.
- Procurement Background: The client conducted multiple surveys of valve manufacturers in South Africa and China before ultimately choosing Yuming, primarily due to the factory's large-scale production capacity, mature manufacturing experience with American standard products, and past successful implementation cases in African oil and gas projects.

III. Customized Solutions
- Product Selection Options
- APIWCB Flanged Ball Valve: Utilizes a two-piece floating ball structure with hard alloy overlay on the sealing surface. Offers flexible opening and closing, erosion resistance, and zero leakage. Serves as the main shut-off valve for pipelines, suitable for high-pressure natural gas transmission.
- Cast Steel Gate Valve: Features a wedge-type hard seal structure, resistant to high temperature and pressure. Used for isolation and maintenance shut-off in long-distance pipeline trunk lines, ensuring pipeline network operation and maintenance safety.
- SwingCheck Valve: Prevents natural gas backflow, avoiding pipeline pressure backflow that could damage upstream equipment, and stabilizing the pipeline pressure system.
- Basket Filter: Installed at the pipeline upstream, filters impurities and dust from the gas, protecting downstream valves, compressors, and other precision equipment from wear and blockage.
- Spring-loaded Safety Valve: Serves as a pipeline overpressure safety protection device. Automatically releases pressure when pipeline pressure exceeds the limit, mitigating the risk of explosion.
- Production and Quality Control Solution
All valves are manufactured strictly according to API 6D and API 600 standards. Each product undergoes sequential hydrostatic strength testing, air pressure sealing testing, and non-destructive testing. Unqualified products are strictly prohibited from leaving the factory. Valve bodies are coated with weather-resistant industrial anti-corrosion paint, and blue dustproof protective covers are added to the flange ends. Moisture-proof plastic film is wrapped around the valves before shipment to prevent moisture, rust, and damage from impacts during sea transport.
- Export Packaging and Logistics Solution
IPPC fumigated solid wood crates are used for packaging. Solid wood pallets are added to the bottom for easy forklift loading and unloading. The crates are wrapped with multiple layers of stretch film for rain and dust protection, and reinforced with green strapping to prevent loose crates during transport. Each crate is affixed with standardized export markings, clearly indicating the shipper, port of destination, crate number, product details, outer crate dimensions, and gross weight information, facilitating overseas customs clearance and warehouse inventory receipt for customers.
- Delivery and Full-Process Support Services
- Scheduled Production and On-Time Delivery: Upon receiving a formal purchase order from the customer, production is quickly scheduled. All valves are produced, tested, and packaged with rust prevention measures within the agreed timeframe. Domestic trucks are arranged for transportation to the port warehouse. Production photos, packing photos, and loading/delivery videos are provided throughout the process, allowing the customer to track the order progress in real time.
- Technical and After-Sales Support: Before shipment, valve installation specifications and pressure testing precautions are sent to the customer. After the goods arrive on-site, the technical team provides remote video guidance for valve hoisting, flange connection, and pressure testing, promptly answering any installation questions. Orders enjoy an 18-month warranty from the original manufacturer. Regular follow-up visits are conducted to assess equipment operation and provide routine valve maintenance plans.

V.Customer Feedback
All valves successfully cleared customs in South Africa and were delivered to the project site. Upon unpacking and inspection, the valves were found to be in good condition, without any damage or rust, and the quantity and specifications perfectly matched the packing list. The customer highly praised Yuming Valves' product quality, meticulous export packaging, and professional and efficient end-to-end foreign trade services, evaluating Yuming as a trustworthy long-term valve supplier in China.

VI. Long-term Strategic Cooperation
The successful delivery of this South African oil and gas project has formally established a deep cooperative relationship between Yuming Valve and this customer. In the future, for the customer's regional pipeline expansion and old valve technical upgrade and replacement projects, Yuming Valve will continue to purchase American Standard industrial valves, automatic control valves, and safety valves. The two parties will work together to cultivate the energy infrastructure market in South Africa and Southern Africa and achieve long-term mutual benefit and win-win results.
