What is en10255?

EN 10255 Steel Tube Non-alloy steel tube is appropriate to welding and threads. It is mainly used for transporting petroleum and fluids. Light, Medium & Heavy series are available from EN 10255 standard (Galvanized & Black) suitable for Fire Fighting, water lines (Cold & Hot), Gas lines, HVAC lines & Electric Poles.

What is bs1387?

BS 1387:1985 Specification for screwed and socketed steel tubes and tubulars and for plain end steel tubes suitable for welding or for screwing to BS 21 pipe threads (AMD 5830) (Withdrawn)

What is instrumentation tubing?

Instrumentation tubing is generally described as thin-walled tubing with strict requirements to deviation in diameter and wall thickness for leak-free operation on fluid transfer and pressure containment systems in process, oil & gas, natural gas, power, cryogenic, and performance-critical OEM industries.

Is 3589 a standard?

The IS 3589 Pipehave a chemical make-up of 0.20% carbon, . 30% manganese, 0.040% of sulfur and phosphorous. These pipes have excellent corrosion and can suffice in extreme temperatures and pressures….IS 3589 Pipe Specification.

Is tubing measured by ID or OD?

Tubing is measured by the OUTSIDE DIAMETER (O.D.), specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″). Pipe is usually measured by NOMINAL PIPE SIZE (NPS). Although it is related to the outside diameter, it is significantly different.

What is OD tolerance?

The OD under tolerance on all sizes is -0.031”. The over tolerance increases with OD size but for the range of 1-1/2 to 4 NPS the plus tolerance is also 0.031”. This introduces the concept of ovality, where if the pipe exhibited both the maximum and minimum OD permitted, it would be out of round (oval) by 0.062”.

What is ASTM A530?

ASTM A530 Standard. Default Specification for General Requirements for Specialized Carbon and Alloy Steel Pipe.

What is the OD tolerance of a stainless steel tube?

Stainless steel tube & pipe outer diameter tolerances are mostly lower than American standards, and approaching the EU standards. it is more reasonable that the American standard specify the OD tolerance is tight, compared to thickness tolerance.

What is the OD tolerance of pipe?

For pipe over 10 inch as special OD tolerance pipe, the OD shall within vary +1% /-1%. The wall thickness at any point shall be within the below tolerance table. For Seamless and Welded pipe, if definite cut lengths are ordered, the length shall vary within -0mm / +6mm.

What are the basic parameters of stainless steel tube&pipe?

Outside diameter (OD), wall thickness and length are three basic parameters in the process of manufacture and distribution for stainless steel tube & pipe, and these parameters have been standardized.

What are acceptable OD values for tubing and pipes?

Tubes, pipes or solids will have a range of values that would be acceptable and considered as ‘x’ nominal OD. Roundness tolerance (+/- 0.01 inch) would mean the difference between major OD and the minor OD throughout the profile should not be greater or less than 0.01 inches.
