LIANHE stainless steel threaded pipe fittings are designed for dependable connections in industrial, commercial, and residential pipeline systems. The precision-cast stainless steel body provides good mechanical strength, corrosion resistance, dimensional stability, and long-term operating performance.
These threaded fittings are suitable for:
General industrial piping systems
Water supply and water-treatment systems
Oil and compatible fuel pipelines
Gas transmission systems
Household water installations
Pharmaceutical production facilities
Chemical-processing equipment
Food and beverage processing systems
Commercial and residential buildings
General fluid-control applications
The actual suitability of the product should be evaluated according to the working pressure, operating temperature, transported medium, stainless steel grade, thread standard, and installation environment.
For acids, chemicals, or other corrosive media, customers should verify material compatibility before ordering. SS304 and SS316 provide different levels of corrosion resistance, and the appropriate material should be selected according to the specific medium concentration, temperature, and operating conditions.
High-quality stainless steel construction
Excellent corrosion and oxidation resistance
Precision investment-cast fitting body
Accurate female threaded connections
Multiple international thread standards available
Reliable pipeline connection and sealing performance
Wide selection of sizes and material grades
Suitable for industrial and household piping systems
Convenient installation and maintenance
Customized markings and packaging available
OEM production based on customer drawings
Long service life under suitable working conditions
The threaded connection allows the fitting to be installed without welding. This helps simplify pipeline assembly, reduce installation time, and facilitate future maintenance or replacement.
Correct thread selection and professional installation are essential for reliable sealing. Appropriate thread sealant or sealing tape should be selected according to the transported medium and working conditions.
LIANHE performs production-line and final inspections throughout the manufacturing process. Raw materials, casting quality, machining accuracy, threads, surface condition, markings, and packaging are inspected before the products are approved for delivery.
Our main quality-control procedures include:
All incoming raw materials are inspected after arrival at the factory. Material grades and relevant raw-material documents are checked before production.
Product dimensions, machining details, threads, markings, logos, and surface condition are inspected during manufacturing.
Packaging materials, quantities, labels, product protection, and shipping marks are checked during the packing process.
Finished-product quality and export packaging are checked during final inspection before shipment.
Additional dimensional, material, pressure, or third-party inspections can be arranged according to customer requirements and the confirmed inspection plan.
Quality documents and inspection reports can be supplied according to the product type, order requirements, and agreed inspection scope, including:
EN 10204 3.1 Material Test Certificate
Raw-Material Inspection Certificate
Radiographic Testing Report, when applicable
Dimensional Inspection Report
Thread Inspection Report
Surface Inspection Report
Third-Party Inspection Report
Other customer-requested quality documents
The availability of specific reports should be confirmed before ordering. Radiographic testing and third-party inspection may involve additional testing costs and production time, depending on the required inspection standard and sampling scope.
Our manufacturing facility is equipped with five automatic CNC lathes, thirty CNC lathes, five tapping machines, one laser-cutting machine, three cutting machines, three polishing machines, one laser-marking machine, one packaging machine, and other related manufacturing and inspection equipment.
