ASTM B88 Type L M K Bronze Copper Pipe for Water System

Copper tubing is most often used for supply of hot and cold tap water, and as refrigerant line in HVAC systems. There are two basic types of copper tubing, soft copper and rigid copper. Copper tubing is joined using flare connection, compression connection, or solder. Copper offers a high level of corrosion resistance, but is becoming very costly.Types: Soft copper , Rigid copper ,Soldered connections , Compression connections , Flare connections , Crimped or pressed connectionsC11000 (CDA 110 / Cu-ETP) Electrolytic Tough Pitch (ETP) CopperC11000 (CDA 110 / Cu-ETP) Electrolytic Tough Pitch (ETP) Copper CDA 110 ETP, SAE J461, ASTM B124, ASTM B152, ASTM B187, ASTM B188, ASTM B272High electrical and thermal conductivity, good corrosion resistance and solderability. C11000 copper is used for welding fixtures, anodes, bus bar in electrical power installations, ground straps, commutators and current carrying hardware. Its inherent fabrication qualities readily permit it to be bent, soldered, drilled, peened, riveted and formed to fit almost any design specification. This beryllium copper has excellent hot workability.  Physical PropertiesEnglish UnitsMetrics UnitsDensity0.322 ib/ln3 @ 68oF8.92 g/cm3Thermal Conductivity226 BTU-ft/ft2-hr-oF390 W/mKElectrical Resistivity10.3 ohm circ mils/ft1.71 microhm/cmElectrical Conductivity (annealed)101 % IACS*0.586 megamho/cmModulus of Elasticity17,000,000 psi117 kN/mm2Coeff. of Thermal Expansion    68-572oF (20-300oC)9.8PPM/oF17.64 PPM/oCMechanical PropertiesTemper1Tensile StrengthYield Strength2% Elongation2Typical 90o Bend Formability GW/BW3ksiN/mm2ksiN/mm2Annealed (Soft)426-38180-260107035--1/4 Hard34-42235-2903222023-0.31/2 Hard37-46255-3153725520-0.53/4 Hard41-50285-34543295140.30.8Hard43-52295-3604531090.81.0Extra Hard47-56325-3855034541.31.5Spring50-58345-4005236031.82.0Extra Spring52 min360 min51 min350 min3 max  Copper Tubing Sizes (CTS) for PlumbingNominal size(OD) [in (mm)] (ID) [in (mm)]Type KType LType M1⁄43⁄8 (9.5)0.305 (7.747)0.315 (8.001) 3⁄81⁄2 (12.7)0.402 (10.211) 0.430 (10.922)0.450 (11.430)1⁄25⁄8 (15.875) 0.528 (13.411) 0.545 (13.843) 0.569 (14.453)5⁄83⁄4 (19.05)0.652 (16.561)0.668 (16.967)0.690 (17.526)3⁄47⁄8 (22.225)0.745 (18.923)0.785 (19.939) 0.811 (20.599)11 1⁄8 (28.575)0.995 (25.273) 1.025 (26.035) 1.055 (26.797)11⁄41 3⁄8 (34.925)1.245 (31.623)1.265 (32.131)1.291 (32.791)11⁄21 5⁄8 (41.275) 1.481 (37.617) 1.505 (38.227)1.527 (38.786)22 1⁄8 (53.975)1.959 (49.759)1.985 (50.419)2.009 (51.029)21⁄22 5⁄8 (66.675)2.435 (61.849) 2.465 (62.611)2.495 (63.373)33 1⁄8 (79.375)2.907 (73.838)2.945 (74.803) 2.981 (75.717)   /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
