Purple copper tube parts standard? It has been mentioned that the standard can be divided into the United States standard purple copper tube parts, United Kingdom (Europe) standards and gb. We simply say that the standard of the next purple copper tube from these three systems.
1, the United States standard:
Standard: ANSI/ASMEB16.221995/1998 standard provides the material, size and tolerance, mechanical properties of the technical requirements and inspection methods.
Size range: 1/4 '- 12' (DN10_DN300mm)
Pipe wall thickness: only one series, suitable for K, L, M three types of brass.
State: hard state.
2, United Kingdom (Europe) standards:
Standard: EN1254 - 1998
Size range: 6 - 108 Phi Phi
Wall thickness: only one kind of thickness is suitable for many kinds of wall thickness copper tube.
3, gb:
Standard: GB/T11618 - 1999
Size range: Phi 6- Phi 219 (DN5-DN200mm)
Wall thickness: two kinds of PN1.0MPa and PN1.6MPa.
Purple copper parts standard know, we come back to say that the standard of copper:
1, the United States standard:
Standard: ASTMB88-1996 standard provides the material, size and tolerance, mechanical properties of the three aspects of technical requirements and inspection methods.
Size range: 1/4 '- 12' (DN10, DN300mm)
Wall thickness: K, M, L three types, M type for the thin walled economy, L and K suitable for higher pressure systems, such as steam or medical gas and other systems.
Status: soft or hard tube.
2, United Kingdom (Europe) standards:
Standard: EN1057 - 1996 (replace the original standard BS2871 - 1971)
Size range: Phi 6- Phi 267 (DN5-DN250mm)
Wall thickness: there are a variety of optional thickness, the details of the reference standard.
On the market more than two series of the original BS2871 standard recommended series:
X series a thin walled economy;
Y series a high pressure situation.
Status: R220 soft state (phi 6- Phi 54), R250 (semi hard for 6 - 159 R290, phi) (phi phi 6 hard - 267).
3, gb:
Standard: GB/T18033 - 2007
Size range: for 6 - 219 (DN5 - 200mm) 13
Wall thickness: there are a variety of optional thickness, but the standard recommended A, B, C three series.
C class is essentially equivalent to the BS2871-X series;
B class is essentially equivalent to the BS2871-Y series or ASTMB88M series;
Class a basically equivalent to ASTMB88L series and K series.
State: soft state (M), semi hard state (Y2), hard state (Y).
Outer diameter tolerance: general precision and high precision grade two, which according to the requirements of the ASTMB88 or EN1057.
Comparison of standard material for copper tube:

The standard name American Standard European standard GB
Brass brass and copper fittings with NSF quality certification must be deoxidized copper. Components meet: Cu and Ag content of not less than 99.90%, the phosphorus content in 0.015%-0.040% T2 or TP2, wherein TP2 is deoxidized copper
T2, T3 or TP2, wherein TP2 is deoxidized copper
Copper fittings without NSF water quality certification requirements of the tube can be used in bronze, zinc shall not exceed 16%, generally B584C84400 ASTM. Ingredients: 81% copper, 9% zinc, 3% tin, 7% lead free NSF water quality certification requirements of the tube can be used in the use of alloy copper, but is not more than 10%, for the pipe containing zinc more than 10% of the test of its ability to resist zinc, and the pipe pieces of its anti B level: A or
Remarks
1, American Standard and oubiao require copper tube or pipe fittings made of copper and oxygen without making clear that gb.
2, with the European standard for American Standard have restricted the content of zinc and copper alloy pipe fittings GB did not make clear regulation.
The copper pipe specifications?

The average diameter of the project of the project of the project allows the deviation of the pipe diameter to allow the deviation of copper pipe and fittings to allow the clearance range.
