HISTORY OF SPIRAL WELDED STEEL PIPE AND SPIRALSTEEL PIPE INTRODUCTION

 HISTORY OF WELDED STEEL PIPE AND SPIRALSTEEL PIPE INTRODUCTION

 

pes for water provide began to become applied about 2500 B.C. The Chinese transported water by way of bamboo. In

Southern Europe and also the Near East, tile pipes had been crafted to provide water for the baths of kings and emperors. The

age of iron began about 1000 B.C. Classical historians don?ˉt spend their time investigating pipes; on the other hand, bits of

information and facts on pipe improvement have already been recorded by engineers. 1 such document is History of Steel Water

Pipe by Walter H. Cates, who spent his expert lifetime designing steel pipes with Consolidated Western Steel, a Division of U.S. Steel Corp. Components on the following are abstracted 

 

WELDED STEEL PIPE INTRODUCTION

 are made by steel strip forming to pipe shape and followed by automatic double-side submerged arc welding (S.A.W.)? are delivered in compliance with DIN, API, EN Standards respectively by other mutually agreed requirements or technical conditons? are manufactured within the range of outdoors nominal diameters from 406 to 1420 mm and also the wall thickness from five.0 to 12.five mm, in the lengths 8 to 18 m or in exact lengths with tolerances corresponding to appropriate requirements. Deliveries of cut-to-lengths pipes lengths from 1.5 to 8 m are also possible in accordance with particular agreements ? are produced from low carbon as well as microalloyed steels with guaranteed weldability ? are meticulously tested employing non-destructive procedures (X-ray, ultrasonic); premium quality and reliability of delivered pipes are guaranteed.

Future of Welded Steel Pipe

Through the 21st Century, demand for pipe will enhance. A worldwide demand for far more cost-effective transportation

will turn into urgent. The cost of trans- portation of fluids per unit weight perunit distance decreases roughly by an

order of magnitude for every single trans- portation mode: from air to surface to ship to pipe. In addition, durable pipe

with longer life will likely be in demand as a result of the too-short design life of many buried pipes now in service. For

pipelines on the 21st Century, design life must be elevated substantially beyond the historical 50-year life.
