Galvanised Steel (GI) Pipes are manufactured using mild steel strips of Low Carbon Galvanized Steel Coils. The strips are passed through a series of fin rolls to give them a circular shape. The slit ends of the strips are then welded together by continuously passing high frequency electric current across the edges. The welded steel pipes are then passed through sizing sections where any dimensiona...

We can provide one or two sampls for free.But if you need more than two samples, the samples will be charged.

Yes, we are factory.Our old factory established in 1997. And we have our own trading company which has export license.

Threaded type crosshole sonic logging pipeOne end welded with pipe fitting threaded outside,the other end welded with inside threading.The middle of the sonic pipes sealed with rubber gasket ring.This connection type applies for thick wall sonic tubes（wall thickness more than 1.8mm）. ...

Crosshole sonic logging pipe for bore pile is a tube solution invented to facilitate the integrity testing of foundations using the CSL(cross sonic logging) testing method. It has been designed for the purpose of facilitating the assembly and installation of long tube lengths in reinforcement cages. ...

Crosshole sonic logging pipe system is a crimping joint system with patented anti-pull step to ensure the connection strength (pull-out strength) is more than 300kgs,as well as high quality seal performance.Features:1. Double seal with anti-pull ring, high performance.2. Joint can be welded on the pipe when supplied,easier and faster operation on site.3. Easy operation with supplied manual hydraul...

Based on thin wall black steel pipes available in different diameters and thicknesses. Our standard length is 5.80 or meters.Then length we can supply is form 3m to 12m. A convenient enlarged bell-mouth allows the connection of 2 tubes seamlessly and strongly, thus greatly reducing labor cost and project schedule. Waterproof design up to 200 meters. The PUSH-FIT system connection between the...

Weldingtype (sleeved type) is the earliest type for crosshole sonic logging pipe. This type ispopular for good price and easier operation. Oneend of the sonic pipe is welded with one sleeve, the outside diameter is morethan that of bottom pipe.. Put the top pipe into the sleeve and weld them. Itbrings less workload and higher operation efficiency. At the same time,safetycan be ensured.
