Inflatable Yokohama Type Floating Rubber Fender Pneumatic Rubber Fender 

1. General introduction

ISO17357:2014 Floating pneumatic rubber fender is an anti-clossion device for marine application in the world. It is made of synthetic-cord-reinforced rubber sheet with compressed air inside to enable it to float on the sea surface and work as a shock absorber when ship to ship transfer operation and ship to dock berthing and mooring operations.

Evergreen floating pneumatic rubber fenders fully company with all requirements on ISO17357:2002 Sstandard. Our products are certificated by CCS, DNV, GL, LR and BV.

 2.  Construction  features
Fast Delivery Marine Pneumatic Rubber Yokohama Fender

The basic body construction of  Floating pneumatic rubber fender consists of outer rubber layers, synthetic-tire-cord layers and inner layers. Please take the picture for reference.

All of these layers are vulcanized together ,and then compress air  inside to enable the fender to float on the sea surface.

Reverse Circulation Water Well Drilling Rig

Reverse circulation (or RC as it`s more commonly known) drilling is an essential tool in the mining industry. In addition to other oil rigs and drill rigs, reverse circulation drills assist in the productivity and accuracy in mining jobs.

RC drilling is a drilling method involving a large rotary drill and Air Compressor that yields high quality mineral and rock samples, free from contamination and material interference.

It is the preferred method of mineral exploration, drilling and in-pit grade control because it is fast and cost-effective.


What is RC Drilling?
Much like air core drilling, RC drilling returns cutting to the surface through an inner tube inside the rod. This is achieved by blowing air down the rods at a rate up to 1500 Pascals. This creates a pressure differential that pushes cuttings and water up via air lift.

The drilling component is powered by a pneumatic reciprocating piston (also known as the hammer), which drives a steel drill bit.

The two most commonly used drilling bits in RC systems are the fixed cutter and roller cone, both of which are advantageous depending on the project and geographical location of the site.

RC drilling is primarily used on large machinery and drill rigs and often goes to depths of 500 metres.

High quality RC equipment also has the ability to dry out the rock with large air compressors before the drill hits, which provides dry rock chips and, in turn, better samples.


Reverse circulation drilling is the predominant technique based on a number of advantages.
.A higher percentage of uncontaminated cuttings
.Drilling rate similar to open hole drilling, but can often be faster and penetrate greater depths
.One of the most accurate drilling methods
.Quick retrieval of sample rates
.Dry samples allow for easier analysis
