BS1387 Steel Pipe: How to Choose the Right Carbon Steel Welded Pipe for Your Project
BS1387 Steel Pipe remains a familiar specification in international steel pipe purchasing, especially for customers looking for welded carbon steel pipes for water, air, gas, construction and general engineering applications. For importers and project contractors, however, choosing the right pipe is not simply about matching a standard number. Pipe size, wall thickness, surface treatment, application and current project requirements all need to be considered.

As a professional carbon steel welded pipe supplier, we provide three practical options: black steel pipe, pre-galvanized steel pipe and hot-dip galvanized steel pipe, helping customers select the most suitable solution for different working environments.
What Should Buyers Know About BS1387 Steel Pipe?
The BS 1387: 1985 pertains to the plain ended welded mild steel tubes suitable for welding or threading, plain ended steel tubes and screwed and socketed tubes, with nominal sizes from DN 8 to DN 150, and three grades of thickness i.e. light, medium and heavy. Nonetheless, it is confirmed by BSI records that BS 1387:1985 was withdrawn and replaced by BS EN 10255:2004.
So when a customer is provided with a project specification that calls for “BS1387 Steel Pipe,” the first thing they need to do is verify the precise applicable specification with the project owner or engineer. This can save a lot of headaches due to ordering a material only by an old commercial designation.
Black, Pre-Galvanized or Hot-Dip Galvanized: Which Pipe Is Right for You?
Different customers have different requirements for corrosion protection and cost.
Black Steel Pipe is a cost-effective option when the pipe is to be utilized indoors, for general fabrication, or structural purposes, or if additional painting or coating will be applied after delivery.
Pre-Galvanized Steel Pipe is processed from zinc coated steel strip and offers a consistent galvanized finish. It is for use in applications where moderate corrosion resistance, good appearance and economical prices are required.
Hot-Dip Galvanized Steel Pipe receives a zinc coating after pipe fabrication. It is generally preferred for outdoor or humid environments where stronger corrosion protection and longer service life are required.
Choosing the correct surface treatment at the purchasing stage can help customers avoid unnecessary coating costs and reduce maintenance requirements later.
How Can Buyers Avoid Common Purchasing Problems?
Before requesting a quotation, we recommend confirming five key points:
1. Pipe size and outside diameter
2. Required wall thickness or pipe class
3. Black, pre-galvanized or hot-dip galvanized surface
4. Plain end, threaded or other end treatment
5. Required length, quantity and inspection documents
For galvanized products, buyers should also confirm the required zinc coating and applicable coating specification. For example, BS EN 10255 provides options concerning tube ends and coatings.
Providing these details at the beginning allows the supplier to quote accurately and reduces the risk of specification differences after the order is placed.
A Reliable BS1387 Steel Pipe Supply Solution
For overseas customers, product quality is only part of the purchasing decision. Stable production, dimensional consistency, surface quality, packaging and delivery are equally important.
As a carbon steel welded pipe manufacturer, we focus on supplying black steel pipe, pre-galvanized steel pipe and hot-dip galvanized steel pipe for distributors, wholesalers, contractors and project customers.
Our goal is to help customers choose the right pipe according to their actual application rather than simply selling a standard specification.
If you are sourcing BS1387 Steel Pipe or its current equivalent for your project, send us your required size, wall thickness, surface treatment, quantity and destination. Our team can check the requirements and recommend a suitable carbon steel welded pipe solution.
