Specification sheets for plastic pipes and tubes are full of abbreviations. This guide translates the dimensions, grades and tolerance classes into decisions you can actually make.
Use it as a working checklist when you write your next enquiry.
This category covers a family of products rather than a single item. In practice a buyer defines plastic pipes and tubes by three things: the base resin, the format or dimension, and the performance or certification level it has to meet. Typical options in this category include OD 16 mm to 630 mm; PN10 / PN16 pressure ratings; coils and straight lengths. Materials most often specified are Polycarbonate, Polyvinyl Chloride, Polyvinylidene Fluoride, Acrylonitrile Butadiene Styrene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the home appliance sector the decision is usually driven by heat resistance and noise control, with colour consistency as a secondary requirement. Typical end uses include kettle bodies, washer tubs, vacuum housings.
The table below summarises the values that usually decide the material choice.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polyvinylidene Fluoride | 1.78 g/cm³ | 35-55 MPa | -40°C to 150°C |
| Polyvinyl Chloride | 1.38-1.45 g/cm³ | 40-55 MPa | -10°C to 60°C |
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
Polyvinyl Chloride is frequently the default selection here: PVC can be formulated from rigid pipe compound to soft medical grade by changing plasticiser content.
The table below summarises the values that usually decide the material choice.
When you read a supplier quotation, check that the dimension, the resin grade, the colour reference and the tolerance class are all stated. A quotation that only gives a price per piece is not comparable between suppliers.
Beyond the base resin, most suppliers offer UV stabilised, food contact, flame retardant, anti-static and recycled content versions of the same product. Ask which additive package is included, because it is often the difference between a part that lasts three years and one that lasts ten.
Each step below has its own control points, and skipping one of them is where most defects start.
Secondary operations such as printing, welding, machining and assembly are often cheaper to do in the same factory, and they reduce the risk of mismatch between components.
Work through these points in order and most specification mistakes disappear.
Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
Yes. Standard samples are normally free of charge and shipped within three working days; custom samples are charged at cost and credited against the first production order.
We can provide ISO 9001 quality system documentation, material certificates, RoHS and REACH statements, and where applicable food contact, flame retardancy or drinking water approvals. Tell us your target market and we will match the document set.
Yes. {mat1} is one of our regular materials for this item, and we can supply virgin, modified and certified grades with full traceability. Material certificates and test reports are issued per batch.
A new tool typically takes 25 to 45 days depending on cavity count and complexity, followed by T1 samples within one week. Existing tools can usually start production within 10 to 15 days of order confirmation.
Colour is controlled with a masterbatch reference approved by the customer, and every production lot is checked against the approved sample under standard lighting before shipment.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
