FAQ: Technical Terms & Project Queries

Q1: What does PE100 mean for HDPE pipes?

A: PE100 is a high-performance grade of high-density polyethylene, with a minimum required strength (MRS) of 10 MPa. It offers exceptional chemical and crack resistance and is mandatory for high-pressure gas delivery lines (ISO 9080 reference).

Q2: What does SDR (Standard Dimension Ratio) indicate?

A: SDR is the ratio of pipe diameter to its wall thickness. Lower SDR means thicker walls, higher burst and pressure rating. DN150 HDPE gas pipes are typically SDR11 (PN16) or SDR17 (PN10).

Q3: What fusion methods are used for DN150 HDPE pipes for gas delivery?

A: Butt-fusion welding and electrofusion are standard joining techniques, providing homogenous, leak-proof seals in compliance with EN 1555-3 and ISO 21307.

Q4: Are your pipes compliant with international gas pipeline standards?

A: Yes, products are tested and marked according to ISO 4437 (Europe), EN 1555, ASTM D2513 (USA), and GOST R standards.

Q5: What is the maximum working pressure for DN150 HDPE pipes?

A: Up to 1.6 MPa for PE100 SDR11 grade; always validated by hydrostatic burst test (≥3x rated pressure).
