SM Fitting Copper


SM Fitting

Fittings manufactured to the Standard shall have an ambient bursting strength of at least four times the 100° F rated internal working pressure.

Fittings Rating ( rated internal working pressures for annealed temper ASTM B 88 type L copper
water tube are calculated as follows :
P = (2*S*t)/(D-0.8*t)


P = rated working pressure at
temperature (psi)

S = allowable stress at temperature
(psi) from ASME B31.1 or ASME

t = minimum wall thickness (in) from
annealed temper ASTM B 88 for
D = maximum outside diameter (in)
from annealed temper ASTM B 88

S values are found in ASME B 31


The insulation is a double layered structure made of cross linked foam polyethylene with closed cells. The insulation tube is extruded to ensure close tube contact to enhance dew point proofing properties.

The insulation is covered with embossed polyethylene film to prevent the foam creasing.
The insulation tube is good for Anti-UV, heat resistance, low water absorption. Insulated copper tube is mainly used for installation of Air Conditioner, available in standard with lengths of 3-30m.



Copper Tube
The copper tube is soft annealed and is to ASTM B 280 Standard, JIS H3300 Standard & AS/NZ 1571 Standard, suitable for R 22 – R 410 A – R 407 A – R 404 A – R 507 A Refrigerant gases. All tubes supplied with “Pink” capped ends.

The Insulation structure is double butted (layered).
Inner insulation is made from polyethylene (PE) nano composite material made up of  foamed closed cell insulation.

Because of the law hygroscopic and excellent weatherproof characteristics the product is widely applied as an insulation material in cooling/heating systems, frost prevention material for water pipes and anti condensation material for air conditioning systems.

The outer shield is an embossed PE film which http://www.viagrabelgiquefr.com/ provides excellent anti condensation, heat resistant 120oC, high durability and high installation.

Surrounding the inner pipe is another layer of high expansion cross linked PE with closed cell structure.

For annealed Coil

Pancake coils
Pancake coils are the standard soft annealed coils and available in 15 metre lengths and on request. They are particularly suitable for merchandising as they are individually  packed in polythene bags. Because of their shape they are easy to be stored and handled.

Straight lengths
Available in 5.8 metre lengths and on request usually in “hard” temper or if specified – “soft” temper. Streamline Mueller has the capacity to cut lengths as short as 1/2″ accurately. Mill tolerances achievable are to within ± 0,0625″ (1.59mm).

Level wound coils
Level wound coils are especially adapted to long production runs and can be supplied in lengths over 300 metres (1000ft). The chief advantage is the consistency of diameter which enables the coil to be played off a mandrel for long production runs.
