HDPE Pipe Fittings Manufacturers

What’s HDPE Pipe Fittings?

HDPE pipe fittings, also called polyethylene pipe fittings or poly fittings, are used for the connection of HDPE piping systems.

Regularly, the HDPE pipe fittings are available in most common configurations of couplers, tees, reducers, elbows, stub flanges & saddles.,etc.

What’s the the major difference between the HDPE pipe fittings that are made by PE80 material & PE100 material?

The HDPE pipe fittings made by “PE80 material”, are also called PE80 fittings, while “PE100 fittings” means the HDPE pipe fittings made by PE100 material.

PE80 fittings & PE100 fittings are the most common HDPE pipe fittings in the markets.

The major difference between the PE80 fittings & PE100 fittings are density, MFR(melt-flow rate), viscous stress & quasi-static stress. The PE100 material has a higher strain hardening modulus than PE80 material, that makes the HDPE pipe fittings made by PE100 material can perform a better viscous stress and quasi-static stress, which allow the PE100 fittings has a thinner wall for the same pressure ratings.

 

For examples: for the HDPE pipe fittings with same diameter & same designed pressure rating, like: DN200-PN10 bars HDPE pipe, the wall thickness will be 11.9mm for PE100 fittings, while for PE80 fittings, the wall thickness will be 14.7mm.

 

Since PE100 material owes a higher strain hardening modulus & lower MFR, a higher moulding pressure & higher injection temperature shall be requested while producing HDPE pipe fittings made by PE100 material.

 

What kind of HDPE pipe fittings that SUNPLAST can provide?

SUNPLAST is integrated provider of HDPE piping systems，and we can provide the HDPE pipe fittings with various items & specifications.

Easy to assemble & disassemble, labor cost saving & reliable use are the major performances of PP compression fittings. No welding, no special tools need & fast installation allow the PP compression fittings be widely used for water plumbing & irrigation systems for agriculture and Gardening.

The PP compression fittings are the most frequently used unions. Its components are a plastic accessory (5) with the following elements in each side: one nut to close the system (2), one o-ring (4), one washer or insert (3) and one split ring or clearing (1). This last element, when the pipe is inserted and the nut is tight, makes a pressure on the pipe fixing it. The o-ring provides the perfect sealing of the union.

The PP compression fittings are available in various configurations, like couplers, tees, elbows, reducers, reducing tees, female thread or male thread couplers, female thread or male thread tees, female thread or male thread elbows, clamp saddles, tapping saddles.,etc.

 

HDPE Butt Fusion Fittings

The HDPE butt fusion fittings have become the most common & reliable fittings for HDPE pipe connection.

The HDPE butt fusion fittings allow to adopt a thermofusion process, by using HDPE pipe welding machine to fusion both the ends of HDPE pipe/HDPE pipe fittings simultaneously, then  two end surfaces are then brought together under controlled pressure for a specific cooling time and a homogeneous fusion joint is formed.

SUNPLAST HDPE butt fusion fittings can be provided in a diameter dn63mm to dn1200mm. The diameter DN63-800mm can be injection moulded in SDR17 & SDR11, while DN900-1200mm can be provided in FABRICATED TYPE only.

The HDPE butt fusion fittings made by PE100 material can offer a pressure rating of PN16 bars for SDR11 & PN10 bars for SDR17, while PE80 fittings are PN12.5 bars for SDR11 & PN8 bars for SDR17.

SUNPLAST HDPE butt fusion fittings can be offered in various items of reducer, elbows, tees, flanges...etc.

 

HDPE Electrofusion Fittings

HDPE electrofusion fittings are the more reliable & simple solution that are for HDPE pipe connection.

Like HDPE butt fusion fittings, HDPE electrofusion fittings also adopt a thermofusion process to joint to the HDPE pipe, by using HDPE pipe electrofusion machine, the electric power go through the brass wire that is coiled inside the surface of the both of ends of fittings, melting the outer surface of HDPE pipe & inside surface of the HDPE electrofusion fittings.

SUNPLAST can offer HDPE electrofusion fittings from dn20mm to dn630mm with pressure rating SDR11-PN16 bars.

HDPE butt fusion fittings & HDPE electrofusion fittings, which one is better?

HDPE butt fusion fittings & HDPE electrofusion fittings, both are the most common used HDPE pipe fittings.

The below is a comparison table between HDPE butt fusion fittings & HDPE electrofusion fittings:

It is difficult to distinguish which one is better, because both of them reputes excellent performances. The HDPE electrofusion fittings can save installation costs and provider a more reliable jointing while HDPE butt fusion fittings are much lower on material costs.

In addition, for the HDPE pipe with a diameter higher to 200mm, the HDPE butt fusion fittings are a more efficient and economical option.

Shall we use the HDPE pipe fittings in SDR17-PN10 to connect our HDPE pipe in SDR13.6-PN12.5?

No, to guarantee the stability of the pipeline, the HDPE pipe fittings with higher pressure rating or at least same pressure rating as pipeline shall be adopted.

For examples: the HDPE pipe is SDR17-PN10, then the HDPE pipe fittings SDR17-PN10 or higher pressure SDR11-PN16 shall be requested.

Shall we use the HDPE pipe fittings be made in PE100 material to weld our HDPE pipes made in PE80?

Yes, this is available to work. The heat fusion can be done between different generation of material grade.

But to assure the best welding, please try best to use the same generation of HDPE pipe fittings to weld the HDPE pipe.

What technology do HDPE pipe fittings be made? Is it same to HDPE pipe manufacturing?

The HDPE pipe fittings are made by injection moulded technology. The one-time injection moulded with out any jointing makes the HDPE pipe fittings the most reliable solution for HDPE piping systems.

HDPE pipe is made by extrusion moulding, which is different to HDPE pipe fittings. 

Can all HDPE pipe fittings be provided in stock?
