Product advantages:
1, high resistance strength: 304 stainless steel pipe tensile light ≥520Mpa
2, corrosion resistance: the oxide film on the surface of the pipe fittings makes the stainless steel pipe fittings have good corrosion resistance.
3, long service life: stainless steel material life of up to 100 years, pipe life of more than 70 years.
4. Low flow resistance: the inner wall of stainless steel clamping pipe fittings is smooth, and the flow resistance is very low.
5, good seismic performance: high tensile resistance at the compression, so it can effectively reduce the possibility of water leakage caused by water hammer vibration, pipeline resonance and earthquake.
6, high pressure resistance: pipe water pressure performance test, can withstand pressure of 2.5 mpa (that is, 24.5 kg force /CM²)
7, environmental protection: stainless steel materials can be recycled, pollution-free, conducive to sustainable development, and stainless steel waste also has considerable economic value.
8, easy installation: Insert the pipe into the pipe fitting with a special tool clamping in place, than the traditional welding or wire interface is simple.
9, suitable embedded installation: clamping pipe to meet the requirements of embedded installation, can be installed, can also be buried wall installation
10, low comprehensive cost: long service life, no maintenance costs, no hidden water leakage, not easy to age, low temperature and explosion-proof pipe.
11, wear-resistant: stainless steel material can withstand long-term erosion of up to 30 meters/second.
12, health: stainless steel material is a recognized health material that can be implanted in the human body, eliminate secondary pollution of water, and maintain the purity of water.
13, good sealing performance, no leakage;

Product Description

Overview

The High-Strength Stainless Steel Groove 90DEG Elbows are premium pipe fittings designed to change direction in grooved piping systems while maintaining structural integrity and flow efficiency. Constructed from seamless 304 or 316 stainless steel, these elbows feature AWWA C606-compliant grooves and a 1.5D radius for smooth laminar flow, making them ideal for heavy-duty applications requiring vibration resistance and corrosion durability.

Features

Robust Seamless Construction:

Manufactured from extruded or forged stainless steel (304 for general use, 316 for harsh environments), with wall thickness compliant with schedule 40/80 and yield strength ≥250 MPa.

Groove dimensions (width: 12.7mm, depth: 2.4mm) precision-machined to AWWA C606 standards for consistent coupling engagement.

Flow-Optimized Design:

1.5D centerline radius reduces pressure loss by 30% compared to short-radius elbows, with a polished internal bore (Ra ≤1.6μm) minimizing turbulence and scale buildup.

90° angle provides optimal direction change while distributing stress evenly, suitable for high-flow systems (up to 1,000 GPM for 12" elbows).

Installation Flexibility:

Connects to grooved pipes using mechanical couplings (no welding/threading), enabling fast installation in minutes with basic tools, reducing labor costs by 40%.

Available in sizes 2" to 48" NPS, with custom diameters and wall thicknesses for special projects.

Environmental Resistance:

316 stainless steel variant resists chloride-induced pitting (critical in marine and saltwater applications), with a protective passivated surface extending service life by 20%.

Temperature range: -250°C to 800°C (with proper gaskets), suitable for cryogenic liquids and high-temperature steam lines.

Application

Perfect for high-demand piping systems:

Fire Protection: NFPA 20-compliant elbows in sprinkler systems, ensuring reliable flow in commercial buildings and industrial facilities.

Oil & Gas Processing: Diverting flow in refinery pipelines and offshore platforms, with 316 elbows meeting NACE MR0175 for sour gas environments.

Power Generation: Steam and condensate lines in thermal plants, withstanding rapid temperature changes and high-pressure cycles (up to 200 bar).

Water Treatment: Wastewater discharge systems and chemical dosing lines, with 304 elbows compliant with NSF 61 for non-corrosive water applications.

FAQ

Q: Can these elbows be used in underground installations?

A: Yes, but use polyethylene casing or anti-corrosion wrap for extra protection in corrosive soils.

Q: What is the maximum working pressure for schedule 80 elbows?

A: Up to 300 PSI for 304 stainless steel and 350 PSI for 316 stainless steel at 20°C.

Q: Do the grooves affect the elbow's pressure rating?

A: No, the grooved design is engineered to maintain full pressure capacity of the pipe system when properly coupled.

Q: Can I paint the elbow for aesthetic purposes?

A: Yes, use epoxy-based paints compatible with stainless steel; ensure the groove area remains unpainted for proper coupling engagement.
