Seamless pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow - liquids and gases (fluids), slurries, powders and masses of small solids.1. Steel tubing is a hollow steel shape intended for structural purposes and made from carbon, stainless, or galvanized steel further divided as:· Mechanical Tubing is used in low stress applications such as fences, kitchens, restaurants, hospitals, solar panels and made with wall thicknesses up to 10 gauge.· Structural Tubing is for high stress structural application like bridges, buildings, roll cages, and underwater platforms with wall thickness from 3/16" and up. It is often referred to as Hollow Structural Sections or just the acronym HSS.2. Pipe is a hollow structure that is intended to carry material such as liquids, gasses, or even solids. Its wall thickness is described by its Schedule and it is often broken down by type using the method of manufacturing it, either ERW or Seamless.Seamless pipe (and tubing) is made by extruding a steel block or by drilling a solid steel bar. Next, the extrusion or the drilled steel bar is cold drawn through a dye to achieve the diameter and thickness needed. Because this process can cause mechanical hardening, sometimes the material is annealed and straightened as a final process. Seamless Pipe & Tubing is subdivided as:Cold Drawn Seamless, or CDS, exhibits precise tolerances and a good surface finish.Hot Finished Seamless, or HFS, has less critical tolerances and somewhat scaly finish and is not as strong as CDS.Product SpecificationStandardAPI, ASTM, BS, DIN, GB, JISOuter Diameter21.3mm-660mmWall Thickness0.5mm-20mmDia ToleranceControl with in the standard, OD:±1%, WT:±10%Materials10#, 20#, 45#, Q235, Q345, Q195, ASTM A53/ A106/ A178/ A333/ A335, SAE1018, SAE1020, SAE1045, ST37, ST37-2, ST35, ST45, ST52, ST35.8, 19Mn5, 16Mn, SS400, Q345B, 27SiMn, 20Cr, 40Cr, 12CrMo, 15CrMo, 30CrMo, 35CrMo, 42CrMoZinc coatingPre galvanized steel pipe: 60-150g/m²Hot dipped galvanized steel pipe: 200-400g/m²Type of pipe coatingEpoxy powderInspectionISO, BV, SGS, MTCPackingSteel strip packed.
