ELBOW 45 LR 7,1MM 12" MSS SP 75 WPHY70

Specifications:

Type: Elbow

Angle: 45 degrees

Radius: Long Radius (LR)

Thickness: 7.1mm

Size: 12 inches

Standard: MSS SP 75

Material Grade: WPHY70

Characteristics:

Element Composition:

WPHY70: This material grade indicates a high-strength low-alloy (HSLA) steel specifically designed for use in high-pressure and high-temperature piping systems.

Mechanical Properties:

Tensile Strength: ≥ 485 MPa (70 ksi)

Yield Strength: ≥ 345 MPa (50 ksi)

Elongation: ≥ 22%

Applications:

Used in piping systems for oil, gas, and petrochemical industries where high-pressure and high-temperature conditions are present.

Suitable for applications requiring high strength and resistance to corrosion and erosion.

Manufacturing Process:

Fabricated through hot forming processes such as seamless or welded construction.

The raw material is heated and shaped into the desired elbow configuration.

Post-forming processes may include heat treatment and surface finishing.

Quality Control:

Material inspection to ensure compliance with ASTM or other relevant standards.

Dimensional checks to verify accuracy and conformance to specifications.

Non-destructive testing (such as ultrasonic testing) to detect any internal defects.

Visual inspection for surface finish and weld quality.

Other Common Types of Elbows:

90-Degree Elbow: Provides a sharp turn in the piping system.

Short Radius (SR) Elbow: Features a shorter radius, suitable for tight spaces.

Reducing Elbow: Used to connect pipes of different sizes.

Threaded Elbow: Designed with threaded ends for easy installation in threaded piping systems.

Common Q&As:

Q: What is the difference between a long radius and a short radius elbow?

A: A long radius elbow has a longer radius, which results in less frictional resistance and less pressure drop compared to a short radius elbow, which has a shorter radius but is more compact.

Q: Can WPHY70 elbows be used in sour service applications?

A: Yes, WPHY70 material is suitable for sour service applications, provided it meets the requirements of relevant industry standards and specifications.

Q: What is the maximum temperature WPHY70 elbows can withstand?

A: WPHY70 elbows can withstand high temperatures, typically up to 600°F (316°C), depending on the specific operating conditions and alloy composition.

Q: Are WPHY70 elbows weldable?

A: Yes, WPHY70 material is weldable using appropriate welding techniques and filler materials compatible with the material grade.
