Hdpe Pipe Fusion Sdr 11 Fittings

Buying fittings by the container means buying a range, not a part number. This SDR11 electrofusion fitting range page sets out what Qingfa moulds in house, how the sizes run, and where the practical limits are - so a project can be priced and specified in one enquiry instead of ten. Because the tooling is in house, a non-standard diameter or a private-label marking is a normal order rather than a special, and the lead time does not change.

The reason to specify this rather than a stock equivalent: Clear SDR11 high-pressure grade range for PN16 gas or water high-pressure service conditions. Larger wall thickness and higher pressure rating than the SDR17.6 general-purpose range.

Specification at a glance

Sdr11 electrofusion fitting range dimensions

Equal tee, electrofusion

Every figure is a finished dimension in mm. A one-sided tolerance such as +3 or +5 is lower-limit zero, upper limit +3 or +5 mm.

Send the pipe schedule with your enquiry and the socket depth and weld parameters are confirmed for you rather than read off the chart. Non-chart sizes are made to order.

Dimensions are reproduced from the factory dimensional drawing for this range. Confirm the current issue against your project specification, or ask us to re-verify a size in writing, before bulk ordering.

What to confirm at enquiry

Send us the pipe schedule rather than a part number. Diameter, SDR and design pressure between them fix every dimension that matters on this fitting and remove the sizing errors that come from matching catalogues across different standards.

Service conditions

Put simply, it is bought for sdr11 system connection for high-pressure gas and water networks. That covers installations such as:

• Tender pricing, where the quantities are known and the sizes are not yet fixed

• Complete project packages quoted from a pipe schedule

• Distributor ranges that need the full size span from one supplier

• Contractor stock programmes covering several fitting types

Material and standards

It is moulded as one piece from prime PE100 compound; regrind never goes into the pressure-bearing wall. The reference standard is PE100 SDR11; ISO 4427 / EN 12201 / GB/T 13663 / DIN 8074-8075, and because the tooling is in house the same fit is supplied whichever of those standards your specification is written to. The factory holds ISO 9001:2015, CE, SGS, DVGW; documentation is released with the shipping papers rather than held back for a separate request.

Order terms: MOQ and lead time negotiable per size and order quantity, confirm on inquiry

What it is welded to

Works with PE100 SDR11 HDPE pipe, electrofusion/butt fusion welding machine, pipe peeler or cleaning fluid.
