TPU Steel Wire Hose — The TPU Build in the Steel-Wire Family

Home / TPU Steel Wire Hose

The listing, and the family it stands in

The company's catalogue organises its steel-wire hoses as a family with two material builds: the PVC steel wire hose, whose published specification stands on the PVC steel wire hose page, and TPU steel wire hose. The PVC build's published construction — a spiral of steel wire carried in the hose wall — is a fact of the PVC build's record; it is not restated here as the TPU build's construction. For the PVC build, the company publishes a full per-size table. For the TPU build, it publishes the listing. Every figure a buyer needs for the TPU build is settled in the written quotation.

General material background, stated as general knowledge rather than company data: TPU — thermoplastic polyurethane — is the elastomer class generally selected where a hose wall meets abrasive media or repeated flexing, and it generally costs more than PVC in the same construction. They do not rate this build. Abrasion life in a specific duty depends on the wall build, the wire pitch and the medium, and none of those is published for the TPU construction in the company's data.

Figures: the PVC table is not the TPU build's table

The steel-wire family's published data — the per-size table of bores, outside diameters, roll lengths and burst pressures — is reproduced on the PVC build's page and belongs to the PVC construction. The steel wire hose sizes guide carries four columns of the same table — bore, outside diameter, roll length and weight — without its pressure columns. It is not restated here as TPU data, and the two builds should not be quoted against each other from one table. For the TPU build, an enquiry confirms: the bore range offered, the wall build and wire format, working and burst pressure at your bore, the temperature range, roll lengths, and the minimum order. State the medium — in particular if it is an abrasive powder, granule or slurry — the vacuum or pressure the hose will see, and the bend the route imposes, so the quotation answers for the TPU construction and not for the family in general.

Where the duty is the one the PVC build's published data already covers — water, oil, powder, sand and gravel across industry, agriculture and engineering, in the applications the company lists for the PVC build — the comparison between the two builds is a legitimate enquiry to raise: ask for both constructions to be quoted against the same duty statement, each on its own figures, and let the written answers carry the comparison. Compare the two written answers, each on its own figures, rather than the PVC table on one side and general material tendencies on the other.

What sizes does TPU steel wire hose come in?

No size table for the TPU build is published in the company's data, and the PVC build's table is not transferred to it. State your bore in the enquiry and ask for the offered range to be confirmed in the written quotation.

Is it transparent like the PVC build?

Transparency is published for the PVC build's wall. Whether the TPU build is offered in a transparent or translucent wall is a construction fact to confirm in the enquiry — ask it at the build's name, with your bore.

What should an enquiry for the TPU build state?

State the medium and the flexing the route imposes in the duty statement, and ask for the TPU build's figures — and the PVC build's, where both are candidates — each confirmed in writing.
