Steel Wire Hose Sizes — Every Row of the Published Table

Home / Steel Wire Hose Sizes

The full table — diameters, rolls and weight

Three ranges meet on this page and must not be merged. The source table's headline range runs from 1/4 in to 12 in. The per-size rows — all twenty-seven reproduced above — run to 10 in. And the product page on this site, PVC steel wire hose, prints an eighteen-row excerpt of the same table, with the burst-pressure column. Sizes above 10 in appear in the headline range only: for those sizes, the per-size data for your order is confirmed in writing in the quotation rather than read from rows that do not exist.

Pressure data for this family

The source table's pressure notation expresses some values as ranges that include negative figures — a vacuum-rating notation. The product page publishes the unambiguous burst column in its excerpt of the same table. For the rows above, the four unambiguous columns state which bores exist, what they measure outside, how they are rolled and what they weigh; working pressure at your bore is confirmed in the written quotation.

Reading the table like a buyer

Two patterns in the rows reward attention. Roll length shortens as bore grows — 100 m coils at the small end, 50 m through the middle bores, 10 m at the top — which shapes freight and minimums per size; the family's published minimums, set out on the product page, are 500 m on the company's Alibaba storefront with a reference band of about US$0.20 to 0.40 per metre, against a usual MOQ of 3,000 m in the product page's FAQ, both shown with their sources and settled in the quotation. The difference between the O.D. and I.D. columns is the combined thickness of the two walls at any row — 5 mm at the smallest row, 20 mm at the largest — and it is not a vacuum rating for any size; no vacuum figure for this family is published in a form carried on this site. The weight column is reproduced as published in the source table, in grams per metre of hose.

An enquiry for this family names the row — bore in inches or millimetres — the medium from the family's recorded list (water, oil, powder, sand and gravel), and whether the run sucks, delivers or both. The quotation then answers the two things the table deliberately does not: the working pressure at that bore, and the food-grade material option's position if your medium is a foodstuff.

Why does the table stop at 10 in when the range says 12 in?

The headline range and the per-size rows are two different statements in the source data: the headline runs to 12 in, the rows to 10 in. The rows above are the per-size rows; sizes above 10 in are confirmed per order in the quotation.

Two rows are both marked 3/8 in — is that an error?

The source table lists two 3/8 in rows at different millimetre bores — 9 mm and 10 mm inside diameter. Both are reproduced as published; when you enquire at 3/8 in, state the millimetre bore you mean.

Where is the working pressure for my size?

It is confirmed in the written quotation, at your named bore — the position taken for this family's pressure data throughout, explained on the product page.
