The final size, wall thickness, material grade, connection type, dimensional standard, and surface finish should be confirmed according to the intended application and piping-system requirements.
The products can be used with compatible hygienic and food-grade media, including:
Drinking water
Milk and dairy products
Beer
Beverages
Liquid food products
Other compatible sanitary process media
Before ordering, customers should confirm the compatibility of the stainless steel grade with the transported medium, operating temperature, system pressure, cleaning chemicals, and sanitation procedures.
For dairy, beverage, pharmaceutical, biotechnology, food-processing, or other high-purity applications, additional material traceability, surface documentation, inspection, or certification may be required.
The products can be used in a range of hygienic processing and fluid-transfer systems, including:
Drinking-water systems
Dairy-processing pipelines
Brewing and beer-production systems
Beverage-processing equipment
Liquid-food production lines
Food-processing facilities
Pharmaceutical-processing systems
Biotechnology facilities
Cosmetic-production equipment
Clean-in-place piping systems
Sanitary tanks and processing equipment
General hygienic fluid-transfer applications
The final product configuration should be selected according to the applicable dimensional standard, available installation space, connection method, working conditions, and mating pipeline components.

Internal and external mirror-polished surfaces
Customized markings and packaging supported
A smooth internal surface helps reduce the accumulation of process residues and makes routine cleaning more convenient. This supports applications where product purity and cleanliness are important.
Actual hygienic performance depends on the complete piping system, including product geometry, surface roughness, weld quality, gasket materials, drainage conditions, installation procedures, and cleaning processes.
Available dimensional standards include 3-A, SMS, IDF, DIN 11850/11851, ISO 2037, BS 4825, and JIS G 3447.
These standards may use different outside diameters, wall thicknesses, connection dimensions, tolerances, and sealing structures. Products manufactured according to different standards may not be directly interchangeable, even when their nominal sizes appear similar.
Customers should provide the exact required standard, size, wall thickness, connection dimensions, and mating-component information when requesting a quotation.
For replacement or maintenance projects, technical drawings or physical samples are recommended to verify compatibility with the existing piping system.
The weld-end option is designed for permanent integration into a compatible stainless steel piping system. Welding procedures, filler materials, heat control, surface preparation, and post-weld treatment should be selected according to the stainless steel grade and applicable sanitary requirements.
The clamp-end option supports convenient assembly, disassembly, inspection, cleaning, and maintenance. Compatible clamps, ferrules, and sanitary gaskets should be selected according to the applicable dimensional standard, operating temperature, system pressure, and transported medium.
The internal and external surfaces can be mirror polished using a process specified as up to 320 grit.
A polished surface helps improve cleanliness, appearance, corrosion resistance, and resistance to the accumulation of process residues.
If a project requires a specific surface roughness, the required Ra value and measurement location should be stated separately. A grit designation alone does not guarantee a fixed Ra value.
Additional polishing, passivation, cleaning, or surface inspection can be arranged according to project requirements.
Standard product markings may include:
LIANHE logo
Product size
Stainless steel material grade
Applicable dimensional standard
Batch or traceability information, when required
Customer logos, private brands, project numbers, heat numbers, and other customized markings can be applied according to confirmed order requirements.
Products are inspected before shipment. Standard delivery inspection covers:
Stainless steel material grade
Outside diameter and wall thickness
Product dimensions and tolerances
Weld-end or clamp-end dimensions
Internal and external surface condition
Weld appearance, where applicable
Hydrostatic testing, where required
Product markings
Quantities and packaging
Additional inspection items can be arranged according to the applicable standard, intended application, and customer requirements.
Inspection reports and supporting quality documents can be supplied according to the confirmed specifications and order requirements, including:
EN 10204 3.1 Material Test Certificate
Raw-Material Inspection Certificate
Radiographic Testing Report, when applicable
Hydraulic Test Report, where applicable
Dimensional Inspection Report
Surface-Finish Inspection Report
Third-Party Inspection Report
Other project-specific quality documents
The required inspection scope, testing ratio, document type, surface-finish documentation, and third-party witnessing arrangements should be confirmed before production.
Each product is protected with bubble wrap or plastic packaging to reduce exposure to dust, moisture, scratches, and surface contamination.
Products are then packed in export cartons, wrapped with woven-bag protection where required, and consolidated in wooden cases for international transportation.
Customized cartons, customer logos, labels, barcodes, pallet packing, and other export packaging arrangements can be provided according to confirmed requirements.
Our standard payment term is a 30% T/T deposit paid in advance, with the remaining 70% T/T balance paid before delivery. Specific payment arrangements can be discussed according to the order value and cooperation conditions.
Available payment methods include:
T/T bank transfer
Western Union
PayPal
Other mutually agreed payment methods
Available Trade Terms: EXW, FOB, CFR, CIF, DDP, and DDU
Products can be delivered by sea freight, air freight, land transportation, or international express service.
The shipping method can be selected according to the order quantity, package volume, destination, required delivery schedule, and transportation budget.
Minimum Order Quantity: Normally 5–10 pieces, depending on the product specification and current inventory.
We maintain inventory for many regular products and commonly requested sizes. Selected products may have up to 5,000 pieces available. Because inventory levels change continuously, actual quantities and immediate-delivery availability should be reconfirmed when requesting a quotation.
