LIANHE stainless steel male threaded fittings are designed to provide reliable connections in industrial, commercial, construction, and general fluid-transportation pipeline systems. The male threaded end allows the fitting to connect with compatible female threaded pipes, valves, instruments, and equipment components.
The fitting body is manufactured using lost-wax investment casting technology. This production process helps provide consistent dimensions, good mechanical strength, stable product quality, and reliable performance in a wide range of pipeline applications.
Available in SS201, SS304, SS304L, SS316, and SS316L, the fitting can be selected according to the transported medium, corrosion conditions, operating temperature, pressure, installation environment, and project requirements.

LIANHE stainless steel male threaded fittings can be used in a wide range of piping and equipment connections, including:
Industrial fluid pipeline systems
Construction and building-service pipelines
Water supply and water-treatment systems
Natural-gas systems using compatible materials and seals
Oil and compatible fuel pipelines
Environmental protection equipment
Machinery and instrument connections
Commercial and residential piping systems
General fluid-control applications
The final product material and thread configuration should be selected according to the actual working pressure, temperature, transported medium, corrosion conditions, sealing method, and installation environment.
For natural gas, acids, chemicals, and other specialized media, customers should confirm material and sealing compatibility before ordering.
Each product is protected with a plastic bag to reduce exposure to dust, moisture, and surface contamination. The fittings are then packed in export cartons and consolidated in wooden cases when required.
Customized cartons, customer logos, labels, barcodes, pallet packing, and other export packaging arrangements can be supplied according to the confirmed order requirements.
Our standard payment term is a 30% T/T deposit, with the remaining 70% T/T balance paid before delivery. Specific payment conditions can be discussed according to the order value and cooperation requirements.
Available payment methods include T/T, Western Union, PayPal, and other mutually agreed methods.
Available Trade Terms: EXW, FOB, CFR, CIF, and DDP
Products can be transported by land, sea freight, air freight, or international express service.
The appropriate shipping method can be selected according to the order quantity, package volume, destination, required delivery date, and transportation budget.
There is normally no fixed MOQ for standard products. Order quantities can be arranged according to customer requirements and current stock availability.
The minimum order quantity for customized and non-standard products will be negotiated according to the material, dimensions, casting requirements, machining complexity, tooling costs, and actual production conditions.
Free Samples: Free samples may be provided for standard products, subject to stock availability. Sample arrangements for non-standard products should be discussed separately. International express delivery charges are normally paid by the recipient.
Quotation Time for Regular Products: Normally within one working hour after receiving complete product specifications and quantity requirements.
Quotation Time for Non-Standard Products: Normally within one working day after receiving and reviewing the customer’s drawings and technical requirements.
Regular-size products available from stock can normally be delivered within 3–7 days.
The production time for non-standard products is normally approximately 25 days. The actual delivery schedule depends on the material, order quantity, casting requirements, machining complexity, inspection requirements, packaging, and current factory production plan.

The threaded connection enables convenient pipeline installation without extensive on-site welding. This helps simplify assembly, reduce installation time, and make future inspection, maintenance, or replacement more convenient.
Correct thread identification is essential for safe and reliable installation. NPT and BSPT generally use tapered thread structures, while BSPP generally uses a parallel thread. Different thread standards may require different sealing methods and should not be connected interchangeably unless their compatibility has been confirmed.
Appropriate thread sealant, sealing tape, or sealing compound should be selected according to the thread type, transported medium, working pressure, and operating temperature.
Available certificates and quality documents include:
GB/T 19001-2016
ISO 9001:2015
CE documentation for applicable products
EN 10204 inspection documentation, when required
The actual certificate scope and document availability should be confirmed according to the selected product, material, order requirements, and intended market.
LIANHE applies quality-control procedures throughout raw-material inspection, casting, production, machining, surface treatment, product marking, and packaging.
Quality inspectors check each major production process to verify that the products comply with the confirmed dimensions, materials, thread specifications, surface requirements, markings, and packaging instructions.
The principal inspection stages include:
Raw-material grade and documentation inspection
Investment-casting appearance and dimensional inspection
Product machining and thread inspection
Surface-treatment and cleanliness inspection
Product marking and logo verification
Quantity, packaging, and shipping-mark inspection
Final product inspection before delivery
Products are released for shipment only after completing the applicable inspection procedures. Project-specific testing or third-party inspection can be arranged according to the confirmed order requirements.
OEM production is accepted. Stainless steel male threaded fittings can be manufactured according to customer drawings, samples, dimensions, thread requirements, material grades, markings, and packaging instructions.
