1PL - 002 1. Test Coupon Less than 1 inch (25 mm) in diameter: - Min. Qualified Diameter: Size welded (no minimum diameter). - Max. Qualified Diameter: Unlimited (welder can weld any larger size). 2. Test Coupon from 1 inch (25 mm) to 2¾ inches (73 mm): - Min. Qualified Diameter: 1 inch (25 mm). - Max. Qualified Diameter: Unlimited. 3. Test Coupon Greater than 2¾ inches (73 mm): - Min. Qualified Diameter: 2¾ inches (73 mm). - Max. Qualified Diameter: Unlimited. 4. General Notes: - Type and number of tests required are determined by another table (QW-452.1). - It explains that a 2¾ inch (73 mm) outer diameter is equivalent to NPS 2½ (DN 65), which is a common pipe size designation. - A common mistake is that some people assume the outside diameter of the test coupon is the same as the Nominal Pipe Size (NPS). However, they are not the same. For example, a 2-inch (50.8 mm) NPS corresponds to an outside diameter of 60.33 mm. Reference : ASME BPVC.IX-2023

What is the pressure - temperature rating of ASME flange? ◾pressure - temperature rating is the maximum allowable pressure at the specific temperature for a given material. ◾ASME B16.5 is the standard for pipe flanges and flanged fitting that covers flanges sizes from NPS 1/2" to 24" in pressure classes from 150 to 2500 and ASME B16.47 cover sizes from 26" to 60" for classes 75 to 900. ◾Note that the terms "pressure rating", "class", "#", "Lb" are interchangable, i.e. they all refer to the same concept of pressure- temperature performance of flange and other fittings. ◾the designation 150 to 2500 do not refer to any specific measurement and these values are just conventional and dimensionless, method for establishing pressure- temperature rating is as attached:

Change of P-Number: The P-Number classification identifies different base materials, which vary in properties such as strength and toughness. A change in base material affects the mechanical properties of the weld, and requalification ensures the welder is proficient with the new material.

Why is checking reinforcement steel bars upon arrival at the construction site so crucial? Conducting key quality checks ensures structural integrity and longevity. Here are the main points to consider: - Visual inspection for surface condition and manufacturing defects - Dimensional verification for diameter, length, and weight - Bend and rebend tests - Tensile test for yield strength, ultimate tensile strength, and ductility - Chemical composition test - Review of mill test certificates for compliance with standards - Fatigue test for dynamic loading projects - Storage and handling inspection - Documentation and record-keeping - Compliance with relevant national and international standards Regular quality checks guarantee that the steel meets all specifications and codes, enhancing the safety and durability of the structure. #Construction #QualityChecks #StructuralIntegrity

Wondering about your pipe fitting pressure rating? The rated working pressure is determined by the lowest pressure-rated fitting end. For instance, if you have a fitting with a -4 (1/4") male 37-degree tube end and a -6 (3/8") male pipe end, the pressure rating would be based on the lower one. Here's an example: ☑️ The -4 male 37-degree tube end is rated at 34.5 MPa (5,000 psi). ☑️ The -6 (3/8") male pipe end is rated at 21 MPa (3,000 psi). So, the fitting's rated working pressure would be 21 MPa (3,000 psi). Remember, steel tubing pressure ratings may vary. Got more questions?
