Shengli Limited is a source-reviewed supplier profile for fiberglass reinforced pipe, FRP pipe, and fiberglass pipe, with every search topic tied to company-published product or process evidence and separated from buyer-side verification requirements.
Shengli Limited states that it began in 1999 as an East-West joint venture between Shandong Shengli in China and New Zealand trade consultancy Atkin Management Ltd. Operating from Napier, New Zealand, it offers global buyers China sourcing, manufacturing coordination, sales and export services for industrial products. Its composites offer centers on FRP / GRP pipe and fittings and glass-fiber-tape reinforced thermoplastic polyethylene pipe (GFT-RTP). The official site names Shengli Xinda in Dongying as its FRP-pipe manufacturing source, so buyers should confirm the contracting seller, actual factory and quality-responsibility boundary for each order.
The reviewed product and process scope makes this supplier relevant to buyer searches for fiberglass reinforced pipe, FRP pipe, fiberglass pipe, and fiberglass pipe supplier. These phrases describe products or processes supported by the cited public scope; they do not expand the supplier's catalog or replace technical qualification.

This procurement profile is built for engineering and procurement teams comparing a finished FRP or composite component against a controlled drawing, service condition and inspection plan. It organizes Shengli Limited's published products, processes, certificate references and official sources around the primary topic “Shengli Limited FRP Pipe and Fittings.” The objective is to help a buyer decide whether to open a controlled RFQ, not to turn a broad company catalog into an unsupported approval.
Shengli Limited currently lists 4 product or service groups and 5 manufacturing or support capabilities in this reviewed record. The public scope indicates what to investigate, while the buyer remains responsible for drawings, design calculations, standards, current certificates, sample approval and order-specific commercial confirmation. Claims below are attributed to the attached source set unless GetFRP explicitly labels them as qualification guidance.
Shengli positions its FRP / GRP pipe offer for industrial and infrastructure use and says its China supply chain can source or manufacture custom pipe and fittings beyond the examples published online. Its GFT-RTP page describes a glass-fiber reinforced core between inner and outer HDPE layers, with small- and large-diameter and continuous-length supply for oil and gas, water and slurry service. These performance, service-life, patent and application statements are company-published, and the web pages do not provide a complete grade-specific design-standard or certificate schedule for procurement. An RFQ should therefore identify the contracting and manufacturing entities, factory address, resin or thermoplastic matrix and reinforcement architecture, liner, winding or forming process, diameter, pressure class, ring stiffness, joint system, design and test standards, material and batch traceability, third-party inspection, current certificates, MOQ, lead time, packaging, Incoterms, warranty and after-sales responsibility. The GFT-RTP page also states that the pipe cannot be tapped or drilled on site; branch-connection design should be reviewed by the project engineer.
No company-level certification is listed on this profile.
Evaluate Shengli Limited as a potential composite product manufacturer for fiberglass reinforced pipe, verify the public evidence and prepare a comparable RFQ.
Shengli Limited includes this product in its published supply scope. Treat that listing as a starting point: request the current datasheet or drawing, material and construction, available grades or dimensions, guaranteed properties, production site, quotation revision and evidence that represents the exact item offered.
For Glass-fiber-tape reinforced thermoplastic polyethylene pipe (GFT-RTP), buyers should convert the catalog description into an acceptance specification. Confirm standard and custom options, raw-material system, critical tolerances, surface or finish, test basis, sample route, MOQ, lead time and packing. Any alternative proposed by Shengli Limited should be identified explicitly rather than treated as automatically equivalent.
This product broadens the supplier's public portfolio, but GetFRP does not infer approval from a product name alone. Ask Shengli Limited for the grade or model designation, manufacturing route, current technical file, production and test location, batch traceability and the limits that apply to published performance values.
A useful RFQ for China-manufactured products for industry and infrastructure should describe the buyer's application without disclosing unnecessary proprietary detail, then state the measurable product requirements. Compare Shengli Limited's response against the same dimensions, quantity, inspection, documentation, Incoterm and delivery assumptions used for every shortlisted supplier.
Shengli Limited publishes Chinese-manufacturer sourcing and supply-chain coordination as part of its capability scope. Buyers should ask which site and equipment perform the work, the practical size or material limits, the normal control records and whether the proposed order uses the same route. Subcontracted stages should be visible in the quality plan.
The relevance of Custom-manufacturing coordination against buyer specifications depends on the requested product and acceptance criteria. During qualification, request a process flow, critical control points, inspection or test method, operator or equipment qualification where applicable, nonconformance handling and a recent example that represents the offered production route.
For sourcing purposes, Production monitoring and quality-control coordination (company-published) is a capability signal rather than independent verification. Confirm capacity, tooling or fixture availability, setup and changeover assumptions, lot definition, sample approval and traceability. The quotation should identify any limitation that could affect geometry, performance, appearance or delivery.
Buyers evaluating Sales, export and worldwide-delivery coordination should connect the process claim to evidence: an equipment list, controlled procedure, representative report, production photograph or witnessed sample may each answer a different risk. Shengli Limited should also explain how the result is checked before release and recorded for the shipment.
These are sourcing contexts suggested by the published product scope, not confirmed project references. Validate the exact application, design basis and evidence in the RFQ.
Shengli Limited's public scope suggests a potential route for piping, tanks or corrosion-resistant process equipment. The RFQ should define service chemistry, temperature, pressure or stiffness class, liner, structural wall, joints, supports, nozzles, inspection and transport. Project-specific design and evidence remain necessary before the supplier can be treated as a fit.
Shengli Limited's reinforcement range can be screened for laminating, pultrusion, winding, molding or conversion programs. Buyers should confirm grade, sizing, architecture, width, tex or areal weight, package, splice and moisture limits, then run a representative processing trial before approving the material for repeat production.
Shengli Limited's product references indicate a possible fit for transport applications. Qualification should address part revision, material and process, appearance class, dimensional capability, inserts and secondary operations, validation plan, change control, annual volume, service-part obligations and packaging that prevents cosmetic or structural damage.
Shengli Limited's source record currently includes Shengli Official Website, Shengli Company Profile, FRP / GRP Pipe and Fittings Directory, GRP / FRP Pipe Supply Page. These links let a buyer distinguish company-published information from GetFRP's own qualification guidance and return to the original context when a claim changes.
No company-level certification is presently listed in the reviewed profile. That does not prove that no document exists, but it means the RFQ should ask for the quality-system certificate and every product-specific test or approval needed by the buyer rather than assuming a certification from market reputation.
GetFRP last recorded a public-source review date of 2026-08-05. Public websites and catalogs can change after review, so commercial decisions should use newly downloaded files and direct supplier confirmation. GetFRP's public or claimed status describes profile ownership and identity controls; it does not certify every product statement or predict order performance.

Jiangsu Aosheng Composite Materials Technology Co., Ltd. is a Suzhou-based carbon-composite company whose current corporate website and 2026 China Composites Expo listing support carbon-fiber woven and hybrid fabrics, prepreg, wind-blade pultruded plate and composite application development. The official site also presents automotive, sports, hydrogen, aviation and overseas footprints under the Aosheng group. GetFRP therefore assigns measured-demand phrases such as carbon fiber fabric, carbon fiber plate, pultruded, resin infusion and vacuum infusion only where a published product or manufacturing route supports them. Fishing rods may be an end use of prepreg, but they are not listed here as an Aosheng finished product. Likewise, automotive parts, sports products and hydrogen cylinders are marked as group-sector inquiries rather than automatically attributed to the Jiangsu parent factory. Buyers must confirm the exact legal entity, production site and specification behind a quotation. Awards, customer relationships, capacity, CNAS, patent and standards-participation statements on the website remain company claims, not GetFRP verification.
Nanjing Hitech Composites Co., Ltd. publishes an integrated HICOMA and Lica offer spanning pultruded carbon- and glass-fiber profiles, high-performance reinforcement fabrics and structural adhesives. Its current official catalog explicitly lists carbon-fiber plate, rod, tube, channel, rebar and prestressed plate systems; fiberglass beams, channels, angles, tubes, plates, rebar and grating; carbon- and glass-fiber fabrics; and bonding products for wind blades, carbon plate and civil structures. The China Composites Expo directory independently supports the Nanjing exhibitor identity and its pultruded-composite and epoxy-adhesive scope. GetFRP therefore assigns only demand phrases supported by those actual products, including carbon-fiber products, plates, rods, tubes and fabrics, pultruded fiberglass profiles and fiberglass grating. An application, system or performance label is not treated as a substitute for the offered grade, section drawing, laminate architecture, adhesive TDS or project engineering.
Jiangsu Changhai Composite Materials Holding Co., Ltd. is a Changzhou supplier of glass-fiber reinforcement and thermoplastic composite materials. Its current official catalog and the 2026 China Composites Expo directory support roving, chopped strands, chopped strand mat, surface and continuous mat, woven roving, biaxial and stitched combinations, mesh, LFT reinforcement, CFRT tape and glass-reinforced thermoplastic panels. GetFRP assigns measured-demand phrases such as chopped strand mat, fiberglass cloth, fiberglass mat, fiberglass chopped strand mat and fiberglass panels only to these published products. The thermoplastic honeycomb offer is described as a core with continuous-glass-fiber-reinforced CFRT skins, not as a solid fiberglass panel or a claim that every honeycomb grade contains glass. Product-specific roving end uses do not mean Changhai manufactures the customer's finished pipe, SMC part or pultruded profile. The complete current logo was downloaded on 2026-08-26 from the exact CDN asset referenced by the official header, trimmed only to remove transparent canvas, and stored locally by GetFRP. Capacity, market-position and certification statements remain company claims pending certificate- and plant-level verification.
