304 Stainless Steel Fittings: OEM/ODM Services by Yuehua

Understanding the Demand for 304 Stainless Steel Fittings OEM/ODM Partners

Buyers searching for a manufacturer capable of supplying 304 stainless steel fittings on an OEM or ODM basis are typically looking for one thing above all: a factory that can combine material reliability with the flexibility to produce under private specifications, private labeling, or custom packaging. Guangdong Yuehua Stainless Steel Profiles Co., Ltd., operating under the brand name Yuehua Stainless Steel, has built its business model around exactly this requirement, offering direct manufacturing, OEM/ODM supply, and custom manufacturing across its full range of stainless steel pipes and connection fittings.

Company Overview: Guangdong Yuehua Stainless Steel Profiles Co., Ltd.

Founded in 1991 and headquartered in Shantou, Guangdong Province, China, Yuehua Stainless Steel operates as a limited liability company that has been fully self-owned and self-operated since inception. The company traces its origins to the Shantou Yuehua Stainless Steel Floral Tube Profile Factory, relocated in 1996 to the Jinyuan Industrial Park, and later established as Guangdong Yuehua Stainless Steel Profiles Co., Ltd. in Haojiang District, Shantou, in 2007, when a new production base of more than 150 mu commenced operations.

Today the company runs a self-owned industrial campus spanning over 150 mu, approximately 100,000 square meters, including more than 50,000 square meters of production workshops and over 10,000 square meters of warehousing and logistics space. Domestic sales offices in Wuxi, Linyi, Zhengzhou, and Chengdu support the local market, while export coverage extends across Southeast Asia, Japan, Europe, the United States, Canada, the Middle East, and other regions through distributor networks. The company maintains direct distribution agreements in 8 countries and active export relationships with 35+ countries and regions.

Comprehensive OEM/ODM Capabilities for 304 Stainless Steel Fittings

Yuehua’s Category B product line—Stainless Steel Connection Fittings—covers six connection technologies: Double Press, Ring Compression, Grooved Clamp, Weld-Type, Flanged, and Threaded. All are produced in SUS 304, SUS 304L, SUS 316, and SUS 316L, with stable pressure resistance of 2.5 MPa or higher and installation time reduced by 40-60% compared with traditional piping systems.

Double Press (Crimping) Fittings

These clamp-compression fittings are engineered for stainless steel water supply and drainage systems, covering elbows, tees, reducers, connectors, threaded fittings, crosses, flange joints, plugs, and caps. Installation time can be reduced by up to 60% compared with welded joints, working pressure reaches 2.5 MPa, and service life extends up to 70 years under normal use. FKM and silicone sealing ring options, protected by patented sealing ring groove design, provide reliable sealing performance.

Ring Compression Fittings

Ring-press connection fittings avoid on-site welding while delivering mechanical strength approximately 8-10 times that of PP-R pipes. Professional solution treatment supports hygienic water conveyance, and the product range spans elbow, straight/coupling, tee, cross, and union series, manufactured to GB/T 33926-2017.

Grooved Clamp Fittings

Grooved connections eliminate on-site welding for large pipeline projects and are compatible with stainless steel fire protection pipes up to DN250. The range includes grooved couplings, elbows, tees, crosses, reducers, flange adapters, and end caps, suited to fire protection, water supply, HVAC, and industrial piping systems.

Weld-Type Fittings

Developed for high-pressure, high-temperature, and harsh industrial conditions, these fittings use full-penetration TIG and MIG butt welding, with optional socket welding, across a specification range of DN15-DN300. Typical applications include high-pressure steam pipelines, chemical reaction feed pipelines, and oil and gas processing systems.

Flanged & Threaded Fittings

This supplementary series balances installation convenience with maintenance operability. Flanged fittings—including Slip-On, Weld Neck, Blind, and Threaded types—are rated up to Class 150, PN16, and PN25, while threaded fittings in NPT and BSPT sizes from DN15-DN80 support equipment connection and pipeline isolation without welding.

Across all five sub-lines, Yuehua supplies standard finished products as well as OEM/ODM customizable services, with product packaging, dimensions, and connection configurations available for customization.

Quality Assurance and Certification

Yuehua’s quality system is certified to ISO 9001, ISO 14001, and ISO 45001 (with OHSAS 18001 referenced in quality assurance documentation), supported by CE marking for pressure equipment, RoHS compliance, China National Building Materials Certification, Kangju Product Certification, the Pressure Pipe Element Production License, and the Drinking Water Product Hygiene Safety License. Incoming raw steel coils are chemically inspected via high-precision spectrometer to meet ASTM A240 and JIS G4304 requirements, while in-process control includes 100% eddy current testing on all weld seams and online laser dimensional gauging. Final inspection includes hydrostatic pressure testing per GB/T 19228.1 and batch destructive tests per GB/T 19228.2, with QA manager approval required before delivery.

The company holds more than 30 national utility model and invention patents covering pipe manufacturing processes, connection technologies, and sealing ring designs, and its YUE HUA trademark was recognized as a Guangdong Famous Trademark in 2006, alongside recognition as a China Well-Known Brand and a High-Tech Enterprise in Guangdong Province.

Manufacturing Scale and Raw Material Sourcing

Vertical integration runs from raw coil to finished tube: slitting, tube forming, TIG welding, online solution heat treatment, sizing, straightening, polishing, and eddy current testing are all performed within more than 140 pipe production lines and more than 200 fitting manufacturing equipment sets. Annual capacity reaches 80,000 tons of stainless steel pipes and fittings, backed by a minimum inventory of 500 tons of finished goods and 2,000 tons of raw coil for rapid order fulfillment. Raw material comes through strategic partnerships with POSCO, TISCO, and Yongjin.

Global Export Capability and Custom Solutions

For OEM/ODM partners, Yuehua provides bespoke pipe diameters, wall thicknesses, and lengths; custom fitting configurations including NPT, BSPT, and BSPP thread types; non-standard flange drilling patterns; and private labeling with custom packaging. Export documentation includes commercial invoice, packing list, bill of lading, certificate of origin, inspection certificate, and mill test certificate, with shipping modes covering LCL, FCL, break-bulk, and domestic rail freight. Digital batch tracking from raw material receiving to final dispatch is retained for a minimum of 10 years, giving OEM/ODM partners full traceability for regulatory and quality audit purposes.
