Stainless steel pipe fittings are a kind of pipe fittings, which are made of stainless steel so they are called stainless steel pipe fittings. Main stainless steel materials: 304, 304L, 316, 316L. Stainless steel pipe fittings are the collective name of various stainless steel pipe connection workpieces, which can be divided into different categories according to shape, purpose, connection method, etc. It has the characteristics of easy installation, high performance, durability, etc., and has a wide range of applications in various pipeline construction and installation. Hebei Sanvo is one of the quality stainless steel pipe fittings suppliers in China and exports and customizes stainless steel threaded pipe fittings that are cast from high-quality 304/304L/316/316L stainless steel. These stainless steel threaded pipe fittings include pipe elbows, pipe tees, pipe caps, pipe plugs, pipe unions, hose nipples, hex nipples, hex bushings, lock nuts, reducer couplings, and other ss threaded pipe fittings, etc. And because of their corrosion resistance, these threaded stainless steel pipe fittings widely used in industrial and daily life pipeline connections.
As a direct manufacturer and supplier of stainless steel pipe fittings, we specialize in delivering high-performance solutions for industrial, commercial, and residential applications. With ISO 9001 certification and adherence to ASTM/ASME standards, our products are trusted globally for their durability, corrosion resistance, and precision engineering. Below, we break down our core product lines, manufacturing capabilities, and service guarantees, backed by industry certifications and customer testimonials.
Stainless steel pipe fittings are components made of stainless steel (an alloy with at least 10.5% chromium for corrosion resistance) used to connect, redirect, or control fluid flow in piping systems. They include elbows, tees, couplings, valves, and flanges. Key advantages are durability, resistance to rust and extreme temperatures/pressures, and suitability for hygienic or harsh environments.
Iron-carbon alloys with carbon content below 2% are steel, and those with carbon content above 2% are called iron. Steel is widely used because of its toughness, elasticity, and rigidity. For stainless steel, no matter whether the magnet can be attracted or not, as long as it meets its quality standards, it is stainless steel.
Stainless steel pipe fittings are the collective name of various stainless steel pipe connection workpieces, which can be divided into different categories according to shape, use, and connection method.
Elbows (change pipe direction), tees (split flow), crosses (merge flow), couplings/unions (connect pipes), flanges (bolt-connected joints), valves (control flow, e.g., ball/gate valves), caps/plugs (seal pipe ends), and reducers (join different pipe sizes).
We manufacture a comprehensive selection of stainless steel pipe fittings, including:
Butt weld pipe fittings are pieces you weld directly onto pipes to create strong, seamless connections, mostly used in high-pressure or high-temperature systems like industrial pipelines.
Ideal for high-pressure and high-temperature applications.
Available in grades 304/304L, 316/316L, and duplex stainless steel.
Compliant with ASTM A403 and ASME B16.9 standards. 
Socket weld fittings are pipe connectors where you slip the pipe into a socket and weld it around the edge for a strong, leak-proof joint.
Designed for compact piping systems requiring leak-proof connections.
Suitable for small-diameter pipelines in chemical and petrochemical industries.
Manufactured to ASTM A182 and ASME B16.11 specifications. 
Threaded pipe fittings are screw-in connectors that do not require welding, but only connect the pipes through the threads on the threaded pipe fittings for easy installation and removal.
Easy-to-install fittings for low-pressure systems.
Available in NPT, BSPP, and BSPT thread types.
Corrosion-resistant and ideal for water, gas, and oil pipelines. 
Product Process: Silica sol lost wax casting
Pressure: 10KG/CM2 (150LBS), 60kg/cm2 (1000WOG)
Thread Standard: BSPT, NPT, BSP, DIN, etc.
Dimensions: 1/8"-4"
Product Advantages: It is an environmentally friendly product that replaces traditional carbon steel, aluminum, and copper products. The product has a long service life, beautiful appearance, acid and alkali resistance, and corrosion resistance. It is an ideal choice for high-end communities, hotels, and equipment manufacturers.
Stainless steel nipples are short, threaded pipe connectors made of stainless steel. They join, extend, or adapt pipes in plumbing or industrial systems, resist rust and corrosion, and handle water, gas, chemicals, or high-pressure setups.
Short pipe connectors for extending or adapting pipelines.
Offered in seamless or welded variants with customizable lengths. 
Stainless steel pipe flanges are flat, ring-like connectors with bolt holes, used to join pipes, valves, or equipment in a way that’s easy to take apart later, while keeping things sealed tight.
Used to connect pipes, valves, and equipment.
Types include slip-on, weld neck, and blind flanges (ASME B16.5 compliant). 
SANVO is one of the quality stainless steel pipe fittings suppliers in China and exports a variety of stainless steel threaded pipe fittings, including stainless steel elbow, stainless steel tee, stainless steel pipe cap, stainless steel pipe plug, stainless steel pipe union, stainless steel hex bushing, stainless steel hose nipple, stainless steel hex nipple, stainless steel lock nut, and stainless steel reducer coupling, etc. And because of their corrosion resistance, these threaded stainless steel pipe fittings are widely used in industrial and daily life pipeline connections. So, you can buy stainless steel pipe fittings at factory price and high quality from China SANVO.
