Fiberglass Well Casing RFQ — Casing + Screens Duty, Published Spec Windows, and Quote Fields
Buyers search fiberglass well casing, fiberglass casing, or fiberglass well casing and screens when a well program needs a corrosion-resistant casing path that may include screens — and the request often collapses to one vague line: "send fiberglass casing." That hides whether the quote is a casing-only GRE string, a screen-only sand-control line, a combined casing + screens package, or high-pressure line pipe that does not belong in the wellbore RFQ.
This page is not a rewrite of soft fiberglass casing vs traditional API pipes, corrosion-resistance primer, or composite tubular / zonal isolation education — use those as primers only. It is also not a rewrite of live fiberglass casing selection (GRE casing-string RFQ → fiberglass casing PDP) or GRE screen tube selection (screens-only RFQ). This page turns combined well casing + screens duty → RFQ fields into a checklist that feeds Fiberglass Well Casing Pipes And Screens, then request a quote.
Start with duty, not with a label
Name what the string must achieve before you ask for a diameter — otherwise the quote mixes casing-string GRE, screen-only sand control, and surface line pipe:
| Duty | Question the RFQ must answer |
|---|---|
| Well / application class | Water well, coalbed methane, oilfield reinjection / casing repair, deep well, or other (confirm suitability)? |
| Package identity | Combined casing + screens package, casing-string only, or screens only? |
| Plain vs screen share | Are both plain casing and screen intervals required (live combined PDP publishes 80% plain / 20% screen as a composition window to confirm)? |
| Collapse / depth intent | What setting-depth / external-pressure picture must the offer check (live page cites collapse suitability for depths up to 950 m as published)? |
| Pressure / temperature | Which published pressure and temperature envelopes must the formal offer confirm against your fluid? |
| Diameter / length / connection | Which diameter class, joint length, and coupling intent keep quotes comparable? |
| Documents / commercial | Quantity, destination, need-by, and which on-page published standards to confirm — not invent as seals? |
If the open question is casing-string-only vs steel, start from fiberglass casing selection. If it is sand-control screens alone, start from GRE screen tube selection.
Equipment / path map — map to published CNPS pages
Combined commercial path — Fiberglass Well Casing Pipes And Screens — Category: Non-metallic Pipes. Live applications include water wells, coalbed methane, oilfield reinjection / casing repair in corrosive conditions, groundwater, and mining dewatering / slurry injection where corrosion resistance is required. Features published there include collapse resistance for deep wells up to 950 m, corrosion-free construction, screens with 1 mm slots and 10% open area, smooth bore roughness <0.01 mm, and lightweight handling. Technical windows on the same page: diameter ranges DN100–DN250 and DN80–DN400; length 11.6 m per pipe with TAC coupling; composition 80% plain fiberglass casing / 20% screen; pressure windows listed as 10–25 MPa and 0–20 MPa (published windows to confirm — do not invent which applies); temperature Acid ≤65.5°C, Amine ≤93.3°C; material filament-wound fiberglass roving + epoxy; standards listed as API Spec 15HR-2016, ISO 14692-2017, SY/T 6267-2018, SY/T 7043-2016 — cite as published specs to confirm, not as monogram/seal claims. CTA: request a quote.
Casing-string-only (adjacent — do not rewrite) — fiberglass casing selection · fiberglass casing PDP — GRE casing string for casing-damage repair, water-source, and CBM straight wells; published range notes DN100–DN250 and 10–25 MPa as starting points when screens are out of scope.
Screens-only (adjacent — do not rewrite) — GRE screen tube selection — sand-control RFQ when the commercial object is screens, not the combined package.
Line-pipe adjacent (different product) — high-pressure fiberglass line pipe — surface / gathering line pipe, not well casing + screens. Keep that RFQ separate.
Soft primers (cross-link only) — durable alternative to API pipes, corrosion resistance in drilling, composite innovation / zonal isolation education. Soft posts are educational — not Selection & RFQ Fields for the combined PDP.
Steel vs fiberglass (optional) — OCTG hub only when clarifying that steel casing/tubing stays on the metallic path; do not rewrite OCTG selection packs.
Scope stack — well class, package, screens, windows, commercial
- Duty split — combined casing + screens vs casing-string-only vs screens-only vs line pipe; do not merge into one unlabeled "fiberglass casing" ask.
- Application class — water well, CBM, oilfield reinjection / repair, deep well, or other — match names on the combined PDP and confirm anything unlisted.
- Plain vs screen intervals — state whether both are required; use the published 80% / 20% composition window as a starting point to confirm, not a free redesign.
- Screen filtration — slot / open-area needs against published 1 mm slots and 10% open area (confirm in the formal offer).
- Collapse / pressure / temperature — depth and load picture; pressure windows 10–25 MPa and 0–20 MPa as published; Acid ≤65.5°C / Amine ≤93.3°C as published — engineering review owns the well rating.
- Geometry / connection — diameter class (DN100–DN250 and DN80–DN400 as published), 11.6 m length with TAC coupling as published, quantity by plain vs screen line items.
- Standards / documents / commercial — list on-page published specs to confirm; destination; need-by; feed request a quote.
No invented SKUs, model numbers, prices, plants, case studies, or certificate seals/monograms. No inventing which pressure window applies to a specific well.
Fiberglass well casing RFQ checklist
- Duty — combined casing + screens package, casing-string only, screens only, or line-pipe (separate).
- Application class — water well, CBM, oilfield reinjection / repair, deep well, other (combined PDP).
- Package identity — feed combined PDP vs fiberglass casing selection vs GRE screen tube selection.
- Plain vs screen share — intervals required; confirm against published 80% plain / 20% screen window.
- Screen filtration — slot / open-area intent vs published 1 mm / 10% open area.
- Collapse / depth — setting-depth / external-pressure picture (published suitability up to 950 m — confirm in offer).
- Pressure / temperature — which published windows to confirm (10–25 MPa and 0–20 MPa; Acid ≤65.5°C, Amine ≤93.3°C).
- Geometry / connection — diameter class, 11.6 m / TAC coupling intent, plain vs screen quantities.
- Documents / standards — project document list; on-page published specs to confirm (API Spec 15HR-2016, ISO 14692-2017, SY/T 6267-2018, SY/T 7043-2016 — no invented seals).
- Qty / date / related scope — quantities, ship-to, need-by; flag casing-string-only, screens-only, or high-pressure line-pipe lines separately.
Send one brief
A useful fiberglass well casing request fits on one page: duty split, application class, plain vs screen share, filtration intent, collapse/pressure/temperature windows to confirm, geometry/connection, documents, and commercial fields. Keep soft encyclopedia comparisons out of the commercial line items. Missing fields get flagged in review.
