What’s the difference between API 5CT K55 and J55
Chemical and mechanical property: API grade K55 has the same Chemical composition as grade J55, they both have the same yield strength, but the minimum tensile strength of K55(655 MPa or 95 KSI) is higher compared to J55(517 MPa or 75 KSI). API color code (bands): J55tubing end is a bright gre...Read more -
API 5CT J55 Casing&tubing
API 5CT J55 Casing: J55 Casing is placed downhole to provide structural integrity to the wellbore and must withstand external-collapse pressure from rock formations and internal-yield pressure from fluid and gas. It must also hold its own deadweight and withstand the torque and transaxial pressur...Read more -

AWWA Standards flange
WHAT IS AWWA? AWWA Flange Standards differ from ANSI (American National Standards Institute) and ASME (American Society of Mechanical Engineers) certifications in a variety of ways, the most important being their specificity: AWWA standards evaluate properties that particularly affect potable wat...Read more -
What are the differences between casing and tubing
What is casing pipe? Casing is a series of steel pipes that are run into a drilled oil well to stabilize the well, keep contaminants and water out of the oil stream, and prevent oil from leaching into the groundwater. Casing is installed in layers, in sections of decreasing diameter that are join...Read more -
ASTM A420 Carbon & Alloy Steel Pipe Fittings
ASTM A420 is the standard specification for pipe fittings of wrought carbon steel and alloy steel for low temperature service. These fitting, either of seamless or welded construction, are primarily used in pressure piping and pressure vessel service at low temperatures. Metals-Piping can provide...Read more -
