COPPER TUBES


 

Long lasting copper tube is a favorite choice for plumbing, heating, cooling and other systems. In the United States, it is manufactured to meet the requirements of specifications established by the American Society for Testing and Materials (ASTM). Copper Tubes is specially manufactured to meet the ASTM standard. All tubes supplied with the ASTM Standard are absolutely 99.9% pure copper. There are two types of Copper Tubes sub products, which are Seamless Copper ACR Tube that meets ASTM B280 and Seamless Copper Water Tube that meets the ASTM B88. Below are the detailed explanations regarding the ASTM B280 and ASTM B88.

 

 

ASTM B88 (Seamless Copper Water Tube)

 

This specification covers seamless water tube suitable for General Plumbing applications such as underground water service, portable water distribution, gas distribution, and fire sprinkler installation. ASTM B88 Tube is available in three ranges of wall thickness, which are K, L, and M. Types K, L, M, are designated by ASTM standard sizes with the actual outside diameter always 1/8-inch larger than the standard size designation. Each type represents a series of sizes with different wall thicknesses. All inside diameters depend on tube size and wall thickness.  For detail specifications and data about ASTM B88 tubes please click the selections below.

 

ASTM B280 (Seamless Copper ACR Tube)

 

This tube specification is suitable for air conditioning and refrigeration field service. There are two varieties of tubes available with the ASTM B280, which are pancake coil tube and straight lengths.

AEROFLEX closed cell tube and sheet insulation is a flexible, closed cell and lightweight elastomeric material designed for insulating liquid cooling and heating lines. The closed cell structure of AEROFLEX provides many advantages over most rigid insulations for cooling and heating lines, such as :

moisture & vapor resistance without using additional
.....vapor barriers.

stable thermal conductivity ( K. value ) during service, ....due to its dense surface skin and closed cell
....characteristics.

flexibility which makes installation work easy and neat.

outstanding ultraviolet and weather resistance.

AEROFLEX is an ideal insulation for frost control on cold water plumbing. It prevents heat gain and condensation problems on chilled water and refrigerant piplines, and it also prevents heat loss from hot water plumbing, liquid, and dual temperature piping.
 AEROFLEX  closed cell tube insulation is easily installed to pipes or tubing. The factory-applied coating of talcum powder on the thick and smooth inner skin helps speed up preassembly lines. When applied to existing lines tubing should be slit length-wise and snapped into place. Slitting can be done on the job easily with razors, blades, knives ,or shears. Cut edges and joints can be sealed with Aeroseal Adhesive (neoprene base contact cement).
The standard sheet is availible in size of 36" x 48" with a wall thickness from 1/8" to 2" and 0.5mx2m with a wall thickness from 3mm upto 50mm. It prevents heat loss and condensation on large pipelines, tanks, chillers, air ducts, and other irregular shaped vessels.
The pre-cut sheets are ready-cut in sizes to suit large pipe sizes ranging from 4" IPS upwards (1/2" to 2" wall thickness are available in 48" length). The pre-cut series makes fabrication easier and more economical because wastage is eliminated. Moreover, AEROFLEX precut sheet is manufactured to nominal thickness with smooth and dense skins on both surfaces. In addition to excellent insulating properties, the pre-cut sheet also has greater resistance to water vapor penetration and water absorption.
AEROFLEX sheet insulations are also available in continuous roll form. Aeroflex continuous sheet rolls are available from 1/8" (3 mm) to 2" (50 mm) thickness, 48" (1, 220 mm) width x 13' to 100' length or 1,000mm width x 3 m to 30 m length. All insulating sheets are made from the same materials as Aeroflex tubing.
 
AEROFLEX tubes and sheets insulate and prevent condensation when used in operating temperatures down to -57 °C (- 70 °F) and insulate against heat loss up to 125° C ( 257 °F), Within these recommended operating temperatures, it will not affect the thermal efficiency and water vapor permeability of AEROFLEX is unaffected.  
   
   The Closed Cell Structure protects against moisture, and eliminates the need for a vapor barrier in most applications. However, under severe condition of high humidity (90% RH up), high temperature (32 °C up) and low ventilation such as underground piping, "AEROCOAT" (Acrylic Emulsion Paint) is recomended an additional vapor barrier coating.  
   
   AEROFLEX insulation, made from high quality synthetic eiastomers, has low density and closed cell structure. The products, therefore, have a stable low K factor of 0.25-0.27 (at 50-90 °F mean temperature) which can save energy consumption on any heating and cooling lines.  
   
   AEROFLEX tube and sheet insulation has been specially compounded to meet the ASTM Standard No. D 635. U L- 94 V, JIS Standard No. K 6911 and other standards. The products have low smoke density while burning, and unlike other thermoplastic materials, AEROFLEX will not melt nor drip flaming balls; therefore, it will not cause flame transfer.  
   
 

The high elasticity of AEROFLEX insulation minimizes vibrations and resonance inchilled water and hot water pipelines during operation.

 
   
   The flexibility and smooth surface of AEROFLEX offer a neat-finished appearance even at jonts,tees,elbows,and crosses. No decorative or protective coating is required for indoor and outdoor installations.  
   
  The flexibility of AEROFLEX enables quick and easy installation on bent or irregular piping. Due to its low and stable thermal conductivity, AEROFLEX requires a thinner wall than other rigid insulations. Therefore, lesser space is needed for installing AEROFLEX.  
   
  AEROFLEX can be safely handled without causing skin irritation and health hazards. It has superior resistance to fungus growth, vermin or rodent attack, and other chemicals such as acids and alkalies. These make AEROFLEX ideal for protecting pipings from corrosion caused by atmospheric agents and industrial arnbience.

PE. Foam : this plastic insulation is manufactured from polyethylene plastic with a density of approximately 2 Ibs/ft³. Most PE insulation is highly combustible and drops flaming balls (fire balls, causing flame transfer to other materials in buildings such as ceilings, carpets, and furniture.

 

 

 

 

 

 

 

 

 

 

PU.Foam : a polyurethane foam insulation made of polyols mixed with polyisocyanates. Although there may be some self-extinguishing grades,it burns releasing hydrogencyanide gas (HCN), It is one of the most noxious gases which is fatal to victims within a short time (HCN 300 ppm only will be fatally noxious within 2-3 minutes).

 

 

 

 

 

 

 

 

 

AEROFLEX : AEROFLEX is made from high quality synthetic elastomers which are nonhaloginated materials mixed with an optimum quantity of fire extinguishing and smoke suppressing chemicals. It will not melt nor drop flaming balls ( fire balls).It produces low smoke density. The main gases released when burned are hydrogencyanide gas. AEROFLEX is self extingguishing within a short time when the flame is removed .The main flame retardant chemical used in AEROFLEX is aluminium trihydrate (ATH) which when decomposed will give out water serving as a flame retarder under the following equation :

AEROFLEX can be classified as a fire safety insulating material.
