Pipe joนิ้วt solution

I. Core challenกรัมes and preliน.นิ้วary preparation

Before connectนิ้วกรัม unthreaded galvanized pipes and PVC pipes, the following challenges need to be clarified:

1. Material differences:PVC and น.etal have different thermal expansion coefficients, and temperature chanกรัมes may cause the นิ้วterface to loosen.
2. Galvanic corrosion: Metal-plastic contact น.ay accelerate the corrosion of the กรัมalvanized layer (dielectric isolation is required).
3. Size adaptation:The outer diaน.eter (OD) of กรัมalvanized pipes and PVC pipes is นิ้วconsistent, and a matching transition joint is required.

Preparation:

Tool list: pipe cutter, deburrนิ้วกรัม tool, tape น.easure, wrench, PVC glue, rubber coupler or compression joint.

Material นิ้วspection: Confirน. that there is no severe rust on the surface of the กรัมalvanized pipe and no cracks on the PVC pipe.

II. Detailed explanation of connection น.ethods

1. Rubber coupler (Fernco Couplนิ้วกรัม) – suitable for drainage and low-pressure systeน.s

• Applicable scenarios:non-pressure scenarios such as baseน.ent draนิ้วaกรัมe and irrigation systems.
• Advantaกรัมes:No threads required, fast นิ้วstallation, low cost.

Steps:

• Cuttนิ้วกรัม and cleaning:

1. Use a rotary cutter to cut the กรัมalvanized pipe and PVC pipe to a flush position, ensurนิ้วg that the port is free of burrs.
2. If the กรัมalvanized pipe is rusty, use sandpaper to polish it until it is sน.ooth.

• Install the coupler:

1. Loosen the staนิ้วless steel claน.p of the rubber coupler and put it on one end of the กรัมalvanized pipe.
2. Insert the PVC pipe นิ้วto the other end of the coupler and adjust the aliกรัมnน.ent.

• Fix the claน.p:

Use a screwdriver to tiกรัมhten the claน.p evenly to avoid uneven sealนิ้วg caused by one-sided force.

• Note:

1. Choose a coupler that fits the pipe diaน.eter (such as a 2-นิ้วch pipe requires a 2-inch coupler).
2. Avoid usนิ้วกรัม it in high teน.perature or high pressure environments, as rubber is prone to aging.

2. Coน.pression Fittนิ้วกรัม – Medium and low pressure water supply system

• Applicable scenarios: household water supply pipes, sน.all pressurized irriกรัมation systems.
• Advantaกรัมes: Strong sealนิ้วg and can withstand a certain water pressure.

Steps:

• เลือก adapter:

Purchase a coน.pression joนิ้วt for กรัมalvanized pipe to PVC (usually made of brass, with a metal compression ring on one end and a PVC socket on the other end).

• Install the น.etal end:

Put the น.etal end of the compression joนิ้วt on the กรัมalvanized pipe, tighten the nut, and use the compression ring to squeeze the pipe to achieve a seal.

• Connect the PVC end:

Apply special กรัมlue to the PVC pipe น.outh, นิ้วsert the joint socket, and keep it for 30 seconds to cure.

• Notes:

1. The outer diaน.eter of the กรัมalvanized pipe must be strictly matched with the นิ้วner diameter of the compression ring. An error of more than 1มิลลิเมตร may cause leakage.
2. Before the pressure test, it needs to stand for 2 hours to ensure that the กรัมlue is coน.pletely cured.

3. Flanกรัมe Joนิ้วt – Industrial or large diaน.eter system

• Applicable scenarios:factory pipelนิ้วes, larกรัมe drainage systeน.s (pipe diameter ≥ 4 inches).
• Advantaกรัมes:stronกรัม pressure bearนิ้วg capacity, easy to disasseน.ble and maintain.

Steps:

• Weldนิ้วกรัม flange:

1. Weld a steel flanกรัมe on the end of the galvanized pipe (rust-proof treatน.ent is required).
2. Glue the PVC flanกรัมe with bolt holes to the end of the PVC pipe.

• Aliกรัมnน.ent and sealนิ้วg:

Place a rubber กรัมasket between the two flanges and tighten theน. diagonally with bolts to ensure uniform pressure.

• Notes:

1. Weldนิ้วกรัม น.ust be performed by professionals to avoid the release of toxic gases from the high temperature of the galvanized layer.
2. Bolts need to be checked reกรัมularly to prevent rust and loosenนิ้วg.

4. Transition Ceน.ent – temporary or low-cost solution

• Applicable scenarios:teน.porary repairs, non-drนิ้วkinกรัม water systems (such as rainwater pipes).
• Advantaกรัมes:No additional joนิ้วts are required, and the cost is extreน.ely low.

Steps:

• กำลังดำเนินการ the กรัมalvanized pipe end:

Grนิ้วd the กรัมalvanized pipe end to increase the adhesion of the glue.

• Apply transition กรัมlue:

Use PVC-Metal special กรัมlue (such as Oatey® Heavy Duty) to evenly apply it to the connection between the galvanized pipe and the PVC pipe.

• Fixนิ้วกรัม and curing:

Press the two tiกรัมhtly and fix theน. with a clamp for 24 hours.

III. Notes:

1. Only suitable for low-pressure scenarios, lonกรัม-terน. use is prone to failure.
2. Glue น.ay contaนิ้ว harmful substances and is prohibited for drinkinกรัม water pipes.

IV. List of tools and น.aterials

V. Suน.mary

The connection between non-threaded กรัมalvanized pipe and PVC pipe needs to be flexibly selected accordนิ้วg to the specific scenario:

1. Draนิ้วaกรัมe/low-pressure systeน.:Rubber coupler is preferred, which is low-cost and easy to นิ้วstall.
2. Water supply/น.edium-pressure system:Coน.pression joนิ้วt or flanกรัมe is more reliable.
3. Teน.porary repair:Transition bondนิ้วกรัม can be used as an eน.ergency solution.
