What material do you often use for HDPE pipes?
Q:What material do you often use for HDPE pipes?
A: We use 100% virgin raw material for HDPE pipes production. The raw material we mainly use is from SINOPEC Chinese companies.
The Borealis Barsafe HE3490LSH, ELTEX, and SABIC are also available for customization.
What is the difference between HDPE floating pipeline and self floating hose?
Q:What is the difference between HDPE floating pipeline and self floating hose?
A: The HDPE floating pipeline consists of HDPE dredge pipes, floaters and rubber hoses, the floaters need to be installed on the HDPE pipelines to provide sufficient buoyancy to float the pipeline, and the rubber hose will be used to ease the stretching and tearing from waves and winds in the water.
The self-floating hose integrates the function of the floaters and rubber hoses, the hose can float by itself, as there are polyethylene foam plates to supply high buoyancy.
As for the costs themselves, the self-floating hose is expensive due to the raw material and workmanship. But the installation and maintenance will be much less costs.
The costs for HDPE floating pipeline are much cheaper, it is a traditional and cost-effective dredging pipeline in the water. But the installation and maintenance will have more labor costs than a self-floating hose.
Do you have stock pipes with fast delivery?
Q:Do you have stock pipes with fast delivery?
A: We have large stock pipes of regular sizes, ranging from 6inch to 20inch, pressure rate is SDR17/PN10, which can supply distributors and wholesalers immediately for fast delivery.
The HDPE stub end is separate or integrated?
Q:The HDPE stub end is separate or integrated?
A: The traditional HDPE stub end is separately butt welded by butt fusion welding, we also invented the integrated HDPE stub end, which is part of the HDPE pipes, by heating to make the stubs.
What is the time frame for HDPE pipe production?
Q:What is the time frame for HDPE pipe production?
A: Usually, the production of HDPE pipes will be within one week, the HDPE stub end welding will need about one week to finish.
What is the marking on HDPE pipes?
Q:What is the marking on HDPE pipes?
A: The standard markings printed on pipes generally consist of nominal size and OD base, pressure class, and production date (day, month, & year).
What is the standard for HDPE dredge pipes?
Q:What is the standard for HDPE dredge pipes?
A: 1. ISO4427 Plastic Piping Systems-Polyethylene(PE) pipes and fittings for water supply
2. IPS/DIPS
What is the flange standard for HDPE dredge pipes
Q:What is the flange standard for HDPE dredge pipes
A: 1. National standard:
2. ANSI B16.9 Class 150 standard/Class 300 standard.
How to connect the HDPE pipes?
Q:How to connect the HDPE pipes?
A: A: By butt fusion welding, usually for underground projects, securing the non-leakage with long service life;
B: By steel flanges, usually for dredging projects, need to move or dismantle
C. By quick connects coupling, which is more popular in the US.
What about the length of the rubber hose?
Q:What about the length of the rubber hose?
A: For discharging rubber hose, the regular length is usually, 1.5m, 2.0m,2.5m,3.0m, etc, and the maximum length we can do is 10m.
