Shanghai Leah Industries Co., Ltd. is a manufacturing facility in Southwestern Shanghai. All founders graduated from Xi’an Jiaotong University, have good experience in reciprocating compressor engineering, manufacturing, sales, service and management.

After worked in the United States two years, Jacky Wu returned back to Shanghai in June, 2015 and established LEAH Industries, devoting to improve the performance of these critical components for reciprocating compressors. LEAH Shanghai has own material laboratory and workshop, is able to control quality, decrease cost, increase efficiency, reduce lead time by ourselves completely. LEAH high performance materials use mature recipes and procedure, good for Oil & Gas / Petrochemical / CNG / LNG / BOG / PET and other industries.

At LEAH we control our materials from the start, which decreases the customer lead time and allows for an efficient manufacturing process. Our capabilities include in-house material blending and testing which enable LEAH to develop proprietary blends that fit your individual application needs and enhance the performance of both Field and Process gas compressors. These in-house capabilities enable us to maintain stringent trace ability controls throughout every stage of manufacturing from compounding materials to finished products, and these records are preserved throughout the product life cycle.

Our expansive portfolio of high-performance polymeric materials combined with on-site engineering and design expertise offers our customers an invaluable resource for transforming advanced engineering materials into high-performance solutions. Our materials portfolio includes an extensive selection of compounds created with the following base resins:

  • PTFE (Polytetrafluoroethylene)
  • PPS (Polyphenylene Sulfide)
  • PEEK (Polyetheretherketone)
  • PI (Polyimide)

This variety of base resins allows for outstanding performance in environments ranging from natural gas and air to bone-dry process gasses. This wide range of application performance is detailed in the Materials Selection Guide.

LEAH’s exceptional Engineering staff combines material, application, and development expertise to create unique solutions for the most demanding industry problems. Our technical staff optimizes the design and manufacturing process by using state-of-the-art programs such as:

  • 3D solid modeling (CAD/CAM)
  • Finite Elemental Analysis (FEA)
  • Mold Flow Analysis (MFA)

Starting with material development and continuing through component design and manufacturing, LEAH provides every service under one roof. LEAH offers a wide array of traditional and modern machining capabilities to manufacture compressor parts, from short runs to full-scale production. We offer some of the most extensive molding and manufacturing capabilities in the industry, including:

  • PTFE, PEEK or PPS series materials, cold and hot compression molding (up to 1,500mm cold / 300mm hot)
  • Piston rings, rider rings, packing rings, wipers and packing cases engineering and manufacturing
  • Compressor plate or ring valves engineering and manufacturing, enforced PEEK plates or rings, high grade springs
  • Present Sloan Brothers lubricators, pumps, divider blocks, check valves and accessories
  • Engineering support and filed service
  • Other spare parts for compressors
