FYPress HDPE Pipes
Product Standard : MS 1058-2: 2005
HDPE or PE is a versatile and commonly used thermoplastic material in cold water piping applications. Today’s modern PE resins are highly engineered for more rigorous applications such as pressure-rated water and gas pipes, landfill membranes, automotive fuel tanks and other demanding applications.
TYPE OF PE MATERIALS
The physical properties of PE materials are specific to each grade or type, and can be modified by both variations in density, and molecular weight distribution. Many grades of PE materials are used in pipe and fitting systems and the specific properties are tailored for the application.
High Density PE (HDPE) types of PE material has been used in our applications. HDPE base resins are manufactured in a low-pressure process, resulting in a chain structure with small side branches and a material density range of 0.9300960 g/cm3. HDPE materials qualify as PE80 and PE100 in accordance with their relative product standard.
STRAIGHT AND ROLLED FORMS
HDPE pipes are supplied in both straight and rolled form (for sizes DN20-DN40). It is highly recommended to use straight pipes for jointing with fittings as the ovality of the pipe diameter is being maintained well compared to rolled pipes.
Rolled pipes cannot restore the pipe diameter ovality completely after uncoiling due to the pipe’s flexural modulus properties. However, rolled pipes can provide connection continuity with less fittings used and less joints being made.
PIPE HARDNESS: PE100 VS PE80 VS PE63
PE100 has higher density than PE80 and PE63, hence offers a higher operating pressure rating and long-term creep resistance at similar wall thickness. PE100 also has a higher surface hardness and deformation resistance. Hard- ness is the ability of a material to resist deformation, which can be determined by a standard test where the surface resistance to indentation is measured.

***The Shore D Hardness test (also called Durometer Hardness Test) is a standardized test used indus- try-wide, the hardness is determined by the penetration of the Durometer indenter foot into the sample. Shore Hardness measures are dimensionless. It goes between 0 and 100. The higher number represents the harder material.
As far as plastic mechanical compression fittings joined with PE100 pipe is concerned, it requires technical know-how and expertise to produce a more reliable mechanical joint.

PE pipe in nature has a characteristic of wide dimensional tolerances. The wide tolerances of pipe Outer Diameter (OD) and Thickness may result in a wide variation of pipe Internal Diameter (ID). The minimum and maximum pipe ID that can be derived over four pipe sizes and two PN ratings are as follows:
For one particular pipe size (DN) of similar PN rating, the difference of minimum and maximum pipe ID is as large as 0.9mm – 1.4mm. However, the minimum ID of lower PN can overlap or be very close to the maximum ID of higher PN.
Inspired by the challenges faced in HDPE pipes with naturally wide variation of dimensional tolerances as well as the increased hardness of PE100 material, the design of our mechanical fittings, ease of installation and reliability of our entire system are based on intensive research, studies and considerations.
FY PRESS utilizes “Crimp” style fittings which are a common and proven type of poly fittings joined by pressing on a metal compression/clinching ring using a pressing tool. The joints formed by this method is very simple and reliable.
SOLUTION FOR PIPES WITH WIDE DIMENSIONAL TOLERANCES
Our proprietary crimp profile employs sub-1/10mm incremental ridges/grooves along an extended fitting insert body length that fits and supports the minimum ID of one higher PN rating of pipe to maximum ID of another lower PN rating of pipes. Pipe insertion for both pressure ratings of pipes will always be easy and the end stop point of pipe insertion will always create firm and secure joints.
SOLUTION FOR CRIMPING HARDER PE PIPES
PE100 pipe has a higher density and hardness compared to PE80 and PE63 pipes. It requires more effort to crimp, which in turn produces a more effective seal than softer pipes. Therefore we utilized metal compression/clinching rings which has double the material density than engineering plastics to provide a higher compressive force that forms more effective seals.
MGA RING
Our MGA Rings have excellent finishing characteristics, high harness, corrosion resistance, and tensile properties that is prominently used for structural purposes and marine applications. The rings are specifically produced using CNC machining process to achieve the highest accuracy of +/-0.1mm.
Our new lineup of fittings are designed for flexibility to handle pipes with natural wide dimensional tolerance, PE100 with increased hardness, easy and less error-prone installation, permanent but replaceable joints, and achieving higher cost effectiveness.
HIGH-PERFORMANCE POLYMER
Our thermoplastic fittings are made of high-performance polymer which offers a strong and sturdy fitting body, which includes precise male and female threads. Both types of threads are designed with a cut-in notch in order to offer smooth and precise thread engagements.
REWORKABLE JOINT
Crimped joints are reworkable by removing the
ring with a cutter and replacing with a new ring.
TOTAL UPGRADE, TOTAL PROTECTION BY FY SHIELD
Our FY SHIELD comes in 4 sizes of DN20, DN25, DN32 and DN40. It is designed to offer complete upgrade and protection for the entire system. This proprietary design’s ideas and innovations features 5 key benefits which are as follows:
- Pipe OD Checker – when the FY SHIELD slips through the pipe, it functions as a gauge checker that can verify pipe ovality and outer diameter consistency.
- Ring Crimp/No Crimp Checker – if the MGA ring has not been crimped, FY SHIELD will not be slotted over the MGA ring. Only when the ring is crimped can FY SHIELD be slotted into place.
- Crimping Zone Checker – in the situation whereby the pipe is not inserted sufficiently or encountered out-of-spec pipes whereby the crimping falls outside of the crimping zone, the FY SHIELD will not be able to reach the Sleeve Retainer, thus notifying that joint is not proper.
- Joint Protector – when the FY SHIELD ‘Clips Onto’ the Shield Retainer properly, it can completely cover up the joint area. This is proven to be the most effective way to protect against severe environments.
- Aesthetic Enhancer – Every joint completed with FY SHIELD enhances its aesthetics and provides a more consistent outlook.
The application of FY SHIELD is very simple and convenient. It only requires sliding on the pipes beforehand and pulled back to be clipped onto the Shield Retainers once jointing is finished.
FY SHIELD is specifically made of translucent materials, hence it can be inspected with a torchlight on their internal condition without having to remove the FY SHIELD in position.
