Temperature-Resistant PVC Suction Hose — High- and Low-Temperature Variants

Home / Temperature-Resistant PVC Suction Hose

Two named variants, one published range

Among the sub-variants named on the suction family's product page, two are temperature builds: high-temperature resistant PVC suction hose and low-temperature resistant PVC suction hose. They are listed as variants of the family's corrugated-wall construction — a smooth flexible PVC inner wall inside a corrugated PVC outer wall — and, as with the family's other variants, they are to be specified explicitly in an enquiry rather than assumed from the base product. The variants' names are published; their individual temperature ratings are not.

The family's published specification

The temperature line is the crux here: -5 °C to +65 °C is the suction family's published service range (suction family range; the figure for your bore and build is confirmed in the quotation), and no wider or narrower figure for either temperature variant appears in the company's data. It would be easy — and wrong — to print a hotter ceiling for the high-temperature build or a colder floor for the low-temperature one. If your duty runs at or beyond the edges of the family range, state the actual service temperature — of the medium and of the environment, which are not always the same — in the enquiry, name the variant you are asking about, and have its rating for your bore confirmed in the written quotation.

The family page, PVC suction hose, carries the family's full context — its recorded applications across construction, municipal and agricultural duties and its thin-wall and thick-wall distinction — against which a temperature variant is specified. A quotation for a hot or cold duty should state the temperature it was written against: state the service temperature in the enquiry, of the medium and of the environment, and ask for the named variant's rating at your bore to be confirmed against it.

Variant questions also combine. A duty can be hot and abrasive, or cold and food-contact, and the family's named variants are not mutually exclusive as enquiry subjects: if your line is, for example, a warm foodstuff transfer, raise the temperature variant and the food-grade variant in the same enquiry, each at its name, and have the single build you are quoted answer both sets of facts in writing.

How hot can the high-temperature variant run?

No separate temperature rating for the variant is published in the company's data; the family's published range is -5 °C to +65 °C (suction family range; the figure for your bore and build is confirmed in the quotation). State your service temperature in the enquiry and ask for the named variant's rating at your bore to be confirmed in writing.

And the low-temperature variant in winter service?

The same position: the family's published floor is -5 °C (suction family range; the figure for your bore and build is confirmed in the quotation), and no colder figure for the low-temperature build is published. State the lowest temperature the hose will see — including overnight storage — and have the variant's position confirmed in the quotation.

Do the variants change the size range?

The family's published bore range is 3/4 in to 8 in (suction family range; the rating at your bore is confirmed in the quotation). Which bores each temperature variant is offered in is confirmed per enquiry, at the variant's name.
