http://www.winlandtrading.comIntroducing the differences between various types of copper pipe's dimensions

Plumbing copper tube, straight length

3/8" O.D. x .032" Wall thickness(10 mm O.D. x 1 mm Wall thickness)

1/2" O.D. x .035" Wall thickness(12 mm O.D. x 1 mm Wall thickness)

3/4" O.D. x .049" Wall thickness(20 mm O.D. x 1.2 mm Wall thickness)

Temperature: If the traced item exceed 4000°F (204°C), the copper tube is not suitable for tracer material

ASTM B819 Standard Specification for Seamless copper tube for Medical Gases Systems

This article introduces the copper tube's dimensions, mass, and tolerances in diameter and wall thickness.

You could check the sizes in inches and milimeters.

Ancient Chinese learned to use copper long time ago, old legends say that the founder of the Xia dynasty (禹) collected brozne from governor of Nine Provinces (九州)and then produced Nine Tripod Cauldrons (九鼎).  Since then Nine Tripod Cauldrons was national treasure for Xia dynasty, Shang dynasty and Zhou dynasty for over one thounsand years.

Nine Tripod Cauldrons stand for nine provinces of acient China, the kinds tried very best to keep them secret and safe.

70% of Chinese copper is produced in these seven places

Introduce standard dimensions and weights, and tolerances in diameter and wall thickness of ASTM B280. Include datas of inches and millimetres , for both hard drawn tubes and annealed coils.

Winland supply various refrigeration and air conditioning tubes. The tubes are supplied in both hard drawn straight length and annealed coils. Our products are  cleaned & capped/degreased. Make sure met the internal cleanliness standards of ASTM B280. Clike to check our copper annealed coils and hard drawn straight tubes.

 

Materials: T2 and TP2 with 99.95% copper

Usage: Widely used in connecting of pipeline in refrigeration and air-conditioning system.
Advantages: Top quality, competitive price, prompt delivery

Technics:Casting, Casting                      Head Code:Square, Round

Type:Tee, Tee                                          Model Number:1/8"-4"

Type: Straight Copper Pipe                             Application:gas water heater, gas water heater

Specification:20-300mm                               Outer Diameter:DN10~DN900

Grade:Seamless Copper Pipe                        Thickness:1mm--8mm

In this artical, we would like to discuss the differences between aluminum and copper pipes for air con (a/c).

  • Specification:OD:2mm~20mm                   Outer Diameter:2-20mm
  • Grade:C11000 C10200 C12000 C12200

Basically, Heating, ventilation and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality

Main production flows for Chinese copper pipe manufacturering

ASTM B280 Standard seamless copper tube,This specification establishes the requirements for seamless copper tube intended for use in the connection, repairs,or alternations of air conditioning or refrigeration units in the field.

 

ASTM B280 Standard seamless copper tube,This specification establishes the requirements for seamless copper tube intended for use in the connection, repairs,or alternations of air conditioning or refrigeration units in the field.

 

Application: Air conditioning & refrigeration, general engineering, oil lines, gas lines and sanitation.

Standard: ASTM B280, ASTM B68, ASTM B75, ASTM B88, ASTM, B837, ASTM 306, EN 1057

Package:Each piece end capped, Bundled with plastic bag; then put in the wooden box or container.

*customization available, the same outside diameter with different wall thickness and length also available.

Combination of length and diameter of the capillary tube can meet the requirements of various conditions & different cooling capacity of the refrigerant device, however the once capillary copper tube is selected and installed, it can not change with the load changes, in order to make the cooling device In the vast majority of time under the high efficiency of operation. So select a representative design is very important

inner grooved copper tube

What is internally Grooved Copper pipe

Internally grooved coppper pipe, or so called inner-grooved copper pipe, means small diameter copper tubes with inner grooving, and in applications of modern air conditioning or heat exchange systems.
