HDPE Pipe Fittings Manufacturers

Whats 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.


Whats 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.

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.

PP compression fittings Specification

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

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.

HDPE Electrofusion fittings

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:

Characteristic

Comparison Between HDPE butt fusion fittings & HDPE electrofusion fittings

Material Costs

The HDPE butt fusion fittings are regular much cheaper prices than HDPE electrofusion fittings. No like electrofusion, the HDPE pipes can be connected by a butt fusion methods, no need special coupler fittings , so less fittings will be requested, and much lower on material costs.

Installation Costs

The HDPE electrofusion fittings can be welded in much simpler way, which can be used for the certain circumstances where butt fusion is not practicable, such as where valves, elbows, and tees must be added. The HDPE pipe electrofusion machine will be much lower on prices. So, HDPE electrofusion fittings will have less installation costs than HDPE butt fusion fittings

Reliability of Jointing

HDPE electrofusion fittings has a more reliable jointing than HDPE butt fusion fittings. The HDPE electrofusion fittings can weld in second times when a leak happens.


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?

To satisfy our customers’ prompt delivery request, SUNPLAST stacks large inventory of HDPE pipe fittings.


Most of HDPE pipe fittings with regular sizes & items are all available in stock, like 63/75/90/110/160/200/250/315/400/450..etc
