"Plug Mill" Technology used for Higher Dia. Seamless Pipes & Tubes Production from 7-inches to 14-inches,is the most reliable technology,in higher dia. Segment. High frequency Induction Welding Technology is used for ERW Pipes &Tubes upto 21-inchesOD.
Our precision cold drawn CDS seamless tube and pipe is produced by piercing hot billets and subsequent rolling which reduces their diameter and elongates them. This material is then passed through a die and over a mandrel plug to produce an accurate size and gauge, this is the essence of the cold drawing process.
Tube plate dia required for tubes only = SQRT ( A T x 4/π ) Dia of the down take : The central well or peripheral downtake is often utilized to collect the concentrated juice in order to remove it from one vessel to the following vessel. According to peter rein down take dia consider less than 25% of the tube plate dia.
The inside diameter of a tube depends on the thickness of the tube. The thickness is often specified as gauge. If we look at Copper Tubes - ASTM B88 the wall thickness of 0.083"of a 2" pipe is gauge 14. Tolerances are commonly higher with tubes compared to pipes and tubes are often more expensive to produce than pipes.
Finned tubes are recommended when the shell-side fluid have a considerably lower heat transfer coefficient than the tube-side fluid. Note, the diameter of the finned tube is slightly smaller than the un-finned areas thus allowing the tubes to be installed easily through the baffles and tube supports during assembly while minimizing fluid bypass.
Boiler tubes for higher temperatures, diameters from 10.2 to 139.7 mm, wall thickness from 0.5 to 16 mm, length 5 – 22 m.
Sep 19, 2005 · Ovality Standard. Generally the pipe bend radius is 5 pipe diameters or greater. On boiler tubes the bend can be tighter depending on design and space limitations. I've see allowable ovality to 10% on tight-radiused boiler tube bends but the target is to set the process up to get below 8% if possible.
The diameter of tubing on the other hand refer to the actual outside diameter. In other words, the actual physical OD of a tube is just the same as it's nominal OD. For example: The actual outside diameter of 1¼" pipe is 1.625″ – while 1¼″ tube has a true 1.25″ outside diameter.

Sep 08, 2017 · The short answer is: A PIPE is a round tubular to distribute fluids and gases, designated by a nominal pipe size (NPS or DN) that represents a rough indication of the pipe conveyance capacity; a TUBE is a round, rectangular, squared or oval hollow section measured by outside diameter ("OD") and wall thickness ("WT"), expressed in inches or millimeters.

Sep 07, 2008 · Common is the 1/32" clearance between tube OD and tube-hole ID (see HG 360.2). This is the common .031" clearance we see in new construction. Rarely, during a repair do we find this hole size on firetube boilers. TEMA has slightly a different take on the clearance, but has a standard as well. NBIC is silent on what size tolerance is acceptable.
