Import Aluminum Expansion Joint — Buy in wholesale FOB from Supplier in Viet Nam

The aluminum expansion joint from Vinh Hung Tcc Jsc. is a flexible piping connector engineered to absorb thermal expansion, vibration, and mechanical movement in pressurised industrial systems. Fabricated from aluminum alloy 6061 or 6063, it incorporates an EPDM or NBR rubber liner to ensure leak-proof performance under cyclic stress. The corrugated bellows configuration provides axial, lateral, and angular movement absorption, making it suitable for pipeline stress relief in HVAC networks, chemical processing plants, and power generation facilities across Southeast Asian and export markets.

Alloy 6061 offers higher tensile strength and fatigue resistance, while 6063 provides superior extrudability and surface finish, typical for corrosive environments. The EPDM liner withstands temperatures up to approximately 120 degrees Celsius with excellent ozone and weather resistance, whereas NBR is selected for hydrocarbon and oil-contact duties. In standard practice, these joints accommodate movement ranges from 15 mm to 300 mm depending on convolution count and pitch, with pressure ratings commonly spanning PN10 to PN25. Fabrication methods include hydroforming or roll-forming of bellows sections, followed by TIG welding of end flanges or pipe nipples to ASME IX or equivalent procedures.

Buyers for this product include mechanical contractors, EPC firms maintaining refinery and power-plant piping, and HVAC distributors serving commercial building projects. When sourcing from Viet Nam, importers should verify the alloy certificate and liner compound specification against their fluid service requirements. Typical trade terms from Vietnamese mechanical-goods exporters are FOB Hai Phong or CIF, though Vinh Hung Tcc Jsc. does not publish confirmed Incoterms or lead times in this listing. Pressure-test certificates, weld procedure documentation, and material mill test reports are the standard documents a buyer should request during technical qualification.

Vinh Hung Tcc Jsc. is headquartered at Lot BT2 - No 49, Bac Linh Dam, Hoang Liet Ward, Hoang Mai District, Hanoi, Viet Nam. The supplier holds a harbor trust tier on the platform, with a response rate of 0.00 percent and an average response time of zero hours recorded, which indicates no historical inquiry engagement is visible to buyers. The company profile does not disclose factory ownership, production capacity, year of establishment, or employee count.

The listing presents Vinh Hung Tcc Jsc. as a source of aluminum expansion joints with alloy and liner specifications stated, but no certifications, quality-management systems, or client references are confirmed in the available data. Buyers should conduct direct due diligence on the supplier's welding qualifications, pressure-testing capabilities, and any ISO or industry-specific certifications held. The Hanoi location suggests proximity to northern Viet Nam's industrial corridor and logistics routes through Hai Phong port.
