Pup Joints are used to adjust the height of full length TUBING or CASING strings. They are also used to adjust the depth of downhole tools.
EASTSUN can customize any length of the pup joint as our customer required. we could offer the sample for free charge but do not pay the cost of freight.
With the subsidiaries of Wuxi Eastsun Trade Co. Ltd and Taizhou Guangfung Oil EquIpment Manufactoty. Established from 2003 Esastsun always focus on OCTG products. The main products of EASTSUN are API 5CT tubing casing pup joint coupling nipple crossover geological drill pipe and line pipe as well as their materials which with different kinds of steel grades and threads.
Our annual production stands at 3,0000 metric tons. We follow quality control system of API5CT and API5L strictly to ensure quality.

1. INTRODUCTION:
This is Powder Test Whiteness Machine/Brightness Tester
The brightness meter is mainly used to test the whiteness of diversified objects such as paper and board, pulps and chemical fiber, textile, plastic, ceramic, enamel, fecula, salt, white cerement, porcelain clay and French chalk, etc. It can also be used to test the optical performance of sheet materials, for example, opacity test.
2. APPLICATIONS:
Paper, Board, Pulps, Chemical fiber, Textile, Plastic, Ceramic, Enamel, Fecula, Salt, White cerement, Porcelain clay and French chalk etc.
3. STANDARDS:
ISO 2469, ISO 2470, ISO 2471, GB/T 7933, GB/T 7974, GB/T 8940.2, GB/T 1840, GB/T 2913, GB/T 13025.2, GB/T, 1543, ISO 2471, GB/T 10339, GB/T 5950 etc.
4. FEATURES:
1). Measure the Blue Reflectance Factor (R457) of samples. Blue Reflectance Factor is so called "Blue Whiteness" or "ISO Brightness".
2). Analyze the sample to find out whether it contains any fluorescent brightener. If so, measure the fluorescent whiteness further, namely whitening rate.
3). Measure the opacity, transparency, light scattering coefficient and light absorbing coefficient.
NO.
