The adaption part, which is the VARINLINE® housing represents the core component within the pocket-free in-line control and measurement system within piping systems.
Defined by the nominal size of the housings as well as by the towering dimension of the attached instruments, up to two instruments can be attached to one VARINLINE® housing.
Only the smaller nominal sizes like DN10 and DN15, as well as ISO 13,5 to ISO 21,3 offer only one instrument to be attached.
To modulate the housings according to different sizes of the tubings, four different sizes of process connections are offered within the range of our VARINLINE® system.
VARINLINE® housing are generally offered with weld ends, as an option different welded-on pipe unions can be delivered.
The nominal sizes of the weld ends are in accordance with the following norms:
- Metric: Outside diameter acc. to DIN 11850, series II; DIN 11866, series A
- Inch OD: Outside diameter based on ASME-BPE-a-2004, DIN 11866, series C
- Inch IPS: Outside diameter acc. to IPS Sch. 5
- ISO: Outside diameter acc. to DIN EN ISO 1127
The standard for surfaces in contact with the product depends on the particular nominal width standard:
- Metric, Inch OD, ISO: Ra ≤ 0.8 μm
- Inch IPS: Ra ≤ 1.2 μm
Higher-quality surfaces are an available option. Surfaces not in contact with the product (housing) are matte blasted as standard. Alternatively, a ground outer surface is available.
