Hot Dipped Galvanized Steel Pipe according to BS 1387
Hot-dip galvanized (galvanizing), also known as hot-dip galvanized, it is an effective anti-corrosion of the metal, mainly used in various sectors of the metal structure facilities.
The rust steel immersed in liquid zinc melt around 500 ℃, steel members attached to the surface of the zinc layer, which play the purpose of anti-corrosion.

Galvanized pipe27.jpgHot-galvanized advantages

·         low-cost processing: hot-dip galvanized anti-rust lower cost than the cost of other paint coating;

·         Durable: standard hot dip galvanized rust thickness can be kept for 50 years or more in the rural environment, without having to patch; standard hot dip galvanized rust layer can be maintained for 20 years in the urban areas or offshore area, without having to patch;

·         good reliability: galvanized layer with steel is metallurgically bonded to become a part of the surface of the steel, and therefore more reliable coating persistent;

·         the toughness of the coating: zinc coating to form a special metallurgical structure, this structure can withstand transportation and use of mechanical damage;

·         full protective: plated parts each part can be plated with zinc, even in the recesses, sharp corners and hiding places can be fully protected;

·         saving time and effort: the the galvanizing process faster than other coating construction method, and can avoid the the brushing time required on site after installation.

BS 1387 : 1985 Screwed and socketed steel tubes and tubulars and for plain end steel tubes suitable for welding or for screwing to BS 21 pipe threads 


 The tolerances on the outside diameter, thickness, mass and length shall be as follows. 

(a) Outside diameter. Medium and heavy tubes as given in tables 4 and 5 respectively

 (b) Thickness Medium and heavy tubes - 10%

 (c) Mass The mean consignment mass for quantities of 150 m and over of one size shall not deviate by more than + 4% from the mass of the consignment calculated from the masses given in tables 3,4 and 5 as appropriate. No single tube shall deviate by more than +10% from the mass given in tables 3,4 and 5 as appropriate. 

(d) Length Random lengths. 

When random lengths are ordered, tubes shall be supplied in one of the following ways:

 (a) in random lengths from 4 m to 7 m ; 

(b) (for orders of over 150 m of any one size of tube) in random lengths from 1.8 m to 4 m provided that the number of such lengths does not exceed 7.5% of the total number of lengths for DN 65 to DN 100 inclusive, and 5% for all other sizes. 

 (c) as for (B) but including tubes with two lengths joined together to make a random length, provided that the number of such jointed lengths does not exceed 7.5% of the total number of lengths for DN 65 to DN 100 inclusive and 5% for all other sizes. 

(2) Mill lengths. When mill lengths are required tubes shall be supplied in lengths of 6.4 m minimum. No tube shall exceed this length by more than 150 mm. 

(3) Approximate lengths. Where approximate lengths are required, either for screwed and socketed tunes or for plain end tubes, each tube shall be within + 150 mm of the specified length. (4) Exact lengths. Where exact lengths are required, either for screwed and socketed tunes or for plain end tubes, each tube shall be within +6 mm of the specified length. NOTE. The purchaser should state in the enquiry or order which lengths he requires
