What is upvc Elbow 6″ 45* GM Local ?
Description & Purpose
-
A 45° elbow is a pipe fitting used to change the direction of flow by 45 degrees in a piping system.
-
In this case, it is for 6‑inch nominal diameter, Schedule 40 (SCH 40), and intended for pressure / water service (rather than just drainage) — sometimes called “pressure elbow” or “pressure fitting.”
-
The “GM” in your query likely refers to a local brand (for example, “GM uPVC”) used in Pakistan (as per listings of GM in local catalogs).
-
These elbows typically have socket (slip) ends (i.e. plain ends into which the pipe is inserted) and are joined using solvent cement (glue / adhesive jointing).
2. Material & Standards upvc Elbow 6″ 45* GM Local
Typical features and standards:
| Property | Typical Value / Range |
|---|---|
| Material | uPVC (un plasticized PVC), rigid, no plasticizer |
| Operating temperature | Up to ~ 60 °C (often lower for pressure service) |
| Pressure rating | Depends on size, wall thickness, and standard — may be given as e.g. PN10 or PN16 in metric systems, or a pressure class in psi in imperial systems. |
| Standardization / Norms | May conform to ASTM D 2466, ISO 4422, DIN 8063, or local standards used by the manufacturer. |
| Socket dimensions (inner socket, depth, wall thickness) | For SCH40, manufacturers publish tables of outer diameter, socket diameter, insertion depth, wall thickness etc. E.g. uPVC 45° elbow SCH40 data: for 6″ size, outer diameter ≈ 168 mm, socket internal dimensions, insertion length, etc. |
| Corrosion / chemical resistance | Good resistance to many chemicals, noncorrosive, smooth internal surface, low friction. |
| UV resistance | Many fittings include UV‑stabilizers (if exposed outdoors). |
-
For 6″, SCH40, outer diameter D₀ = 168.00 mm, socket dimensions (d1, d2) etc.
-
The insertion (socket) depth, wall dimension (d) and “J” value (maybe joint dimension) are also given in that table.
Thus, a GM 6″ 45° SCH40 elbow will likely have socket dimensions conforming to standard SCH40 (or a local equivalent) so as to match 6″ pressure pipes of the same class.
3. Local Brand (GM / GM‑Fit) Specifics
-
GM is a brand name in Pakistan for uPVC fittings. In catalogs, “Elbow 45° 6″” is listed under GM
-
They produce a range of pipe and fittings (1/2″ to 8″) for drainage, sewer, cold water, etc.
-
The local distributor or catalog may list number of pieces per carton, catalog numbers etc.
-
However, the manufacturer should provide a detailed datasheet with exact socket diameters, insertion depth, pressure rating, tolerance, etc. If you get that, you should rely on that for design and installation.
4. Installation Procedure & Best Practices
When installing a uPVC 6″ 45° SCH40 pressure elbow, follow good practices to ensure a leak‑free and durable joint. Below is a stepwise procedure and tips.
4.1 Preparations & Tools Needed
-
uPVC pressure pipe (6″, compatible SCH40 class)
-
6″ 45° uPVC elbow (same class)
-
Solvent cement (pipe adhesive) suitable for uPVC pressure service
-
Cleaner / primer (if recommended)
-
Measuring tape, marker
-
Pipe cutter or saw (with fine blade)
-
Deburring tool or file
-
Clean cloth, rag (for cleaning)
-
Lubricant (if required by manufacturer)
-
Scraper (for removing burrs)
-
Supports, clamps for piping
-
Safety gear (gloves, goggles, etc.)
