Materials and Surface Treatments
1.Main Body Raw Material
Fabricated from ASTM‑compliant SS304 stainless steel, the 45° street elbow delivers outstanding rust and corrosion resistance against water, oil, gas and weak acidic media. It operates stably in food processing, chemical production, water treatment and marine piping systems for pipeline turning connection.
2.Surface Finish
Standard pickling and passivation treatment forms a compact passive anticorrosive film to isolate rust, moisture and mild chemical erosion, supporting reliable use for indoor and outdoor industrial pipelines. Two surface options are available as requested: natural matte finish and mirror polishing finish.
3.Connection Processing
Adopt precision‑machined BSPT / NPT male‑female threads with accurate thread pitch and tooth profile for smooth mating with standard threaded fittings. Proper thread sealant auxiliary ensures stable leak‑proof performance for pipeline turning service.
Standards and Certifications
Our products are manufactured in strict accordance with global industrial quality norms:
- Fabricated following official process specifications for stainless steel threaded pipe fittings
- Production system certified to ISO 9001 quality management standards
Prior to packaging and shipment, every 304 stainless steel 45° street elbow undergoes comprehensive testing. Inspection items include sealing reliability, thread dimensional accuracy and anticorrosion performance.
Applications
1.Petrochemical & Industrial Pipeline
Our 304 stainless steel 45° street elbows work steadily in factory piping systems for water, gas, oil and low‑corrosion fluid transmission. They realize 45‑degree direction change for pipelines to simplify later equipment maintenance and pipeline upgrading.
2.Shipbuilding & Marine Pipeline Systems

Installation Instructions
- Thread Pre‑treatment: Clean the BSPP/NPT threaded sections and matching pipe threads; remove rust, oil stains and burrs before assembly.
- Controlled Torque Fastening: Tighten the fitting with appropriate torque. Excessive tightening shall be avoided to prevent thread deformation and sealing surface damage.
- Pressure Leak Test: Conduct pressure testing after installation to confirm reliable sealing of threaded joints and elbow turning surfaces.
- Periodic Inspection: Inspect threaded connections regularly to guarantee long‑term safe operation of the piping system.
Comply with industrial threaded piping specifications and local safety regulations during installation.

FAQ
Q:Can this 304 stainless steel 45° street elbow be buried underground?
A: Outer anti‑corrosion treatment must be carried out before buried installation. Direct burial without protective measures will greatly shorten the service life of the fitting. We can provide customized anti‑corrosion schemes upon your demand.
Q: What is the standard installation method for this 304 stainless steel 45° street elbow?
A: Clean the thread and sealing surface thoroughly first. Apply suitable thread sealant or PTFE tape, then tighten manually with standard pipe wrenches according to torque requirements. Do not over‑tighten to avoid thread damage, achieving stable long‑term leak‑free connection.
Q: Can it withstand pipeline thermal expansion?
A: The fitting belongs to rigid connecting parts. For long‑distance pipelines with obvious temperature changes, it is suggested to install expansion joints to offset stress caused by thermal deformation.
Q:Is it compatible with different steel pipes?
A:Fits standard NPT / BSPT threaded steel pipes. Please confirm thread specification before ordering.
Q:Why pick 304 stainless steel 45° street elbow rather than carbon steel ones?
A:ASTM 304 stainless steel features outstanding rust and corrosion resistance for water, oil, gas and weak acid media. Standard threaded structure enables easy assembly and disassembly, suitable for piping systems in food processing, water treatment, marine engineering and corrosive medium scenarios.
